Abstract We report the discovery of a new quasar: This object was discovered while reducing spectra of a sample of stars being considered as spectrophotometric standards for the Dark Energy Survey.

The flux and wavelength calibrated spectrum is presented with four spectral lines identified. From these lines, the redshift is determined to be z is approximately equal to 0.

In addition, the rest-frame u-, g-, and r-band luminosity, determined using a k-correction obtained with synthetic photometry of a proxy QSO, are reported as 7.

The finding is detailed in a paper published The newly discovered quasi-stellar object received designation The discovery could be very important for understanding of the early universe, as such high-redshift, quasi-stellar Scientists have created the soundtrack of the 5,th Mars sunrise captured by the robotic exploration rover, Opportunity, using data sonification techniques to create a two-minute piece of music.

Do star clusters harbor many generations of stars or just one? Scientists have long searched for an answer and, thanks to the University of Arizona's MMT telescope, found one in the Wild Duck Cluster, where stars spin at Astronomers have witnessed, in the finest detail yet, a brutal David-vs-Goliath fight between two nearby galaxies that are tearing chunks from each other and flinging them into the gaseous Magellanic Stream, a cosmic river The term "quasar" originated as a contraction of quasi-stellar [star-like] radio source , because quasars were first identified during the s as sources of radio-wave emission of unknown physical origin, and when identified in photographic images at visible wavelengths they resembled faint star-like points of light.

High-resolution images of quasars, particularly from the Hubble Space Telescope , have demonstrated that quasars occur in the centers of galaxies, and that some host galaxies are strongly interacting or merging galaxies.

Quasars are found over a very broad range of distances, and quasar discovery surveys have demonstrated that quasar activity was more common in the distant past.

The peak epoch of quasar activity was approximately 10 billion years ago. The supermassive black hole in this quasar, estimated at million solar masses , is the most distant black hole identified to date.

The term "quasar" was first used in a paper by Chinese-born U. So far, the clumsily long name 'quasi-stellar radio sources' is used to describe these objects.

Because the nature of these objects is entirely unknown, it is hard to prepare a short, appropriate nomenclature for them so that their essential properties are obvious from their name.

For convenience, the abbreviated form 'quasar' will be used throughout this paper. Between and , it became clear from work by Heber Curtis , Ernst Öpik and others, that some objects " nebulae " seen by astronomers were in fact distant galaxies like our own.

But when radio astronomy commenced in the s, astronomers detected, among the galaxies, a small number of anomalous objects with properties that defied explanation.

The objects emitted large amounts of radiation of many frequencies, but no source could be located optically, or in some cases only a faint and point-like object somewhat like a distant star.

The spectral lines of these objects, which identify the chemical elements of which the object is composed, were also extremely strange and defied explanation.

Some of them changed their luminosity very rapidly in the optical range and even more rapidly in the X-ray range, suggesting an upper limit on their size, perhaps no larger than our own Solar System.

They were described as "quasi-stellar [meaning: The first quasars 3C 48 and 3C were discovered in the late s, as radio sources in all-sky radio surveys.

Using small telescopes and the Lovell Telescope as an interferometer, they were shown to have a very small angular size.

In , a definite identification of the radio source 3C 48 with an optical object was published by Allan Sandage and Thomas A. Astronomers had detected what appeared to be a faint blue star at the location of the radio source and obtained its spectrum, which contained many unknown broad emission lines.

The anomalous spectrum defied interpretation. British-Australian astronomer John Bolton made many early observations of quasars, including a breakthrough in Another radio source, 3C , was predicted to undergo five occultations by the Moon.

Measurements taken by Cyril Hazard and John Bolton during one of the occultations using the Parkes Radio Telescope allowed Maarten Schmidt to find a visible counterpart to the radio source and obtain an optical spectrum using the inch Hale Telescope on Mount Palomar.

This spectrum revealed the same strange emission lines. Schmidt was able to demonstrate that these were likely to be the ordinary spectral lines of hydrogen redshifted by Although it raised many questions, Schmidt's discovery quickly revolutionized quasar observation.

Shortly afterwards, two more quasar spectra in and five more in , were also confirmed as ordinary light that had been redshifted to an extreme degree.

Although the observations and redshifts themselves were not doubted, their correct interpretation was heavily debated, and Bolton's suggestion that the radiation detected from quasars were ordinary spectral lines from distant highly redshifted sources with extreme velocity was not widely accepted at the time.

An extreme redshift could imply great distance and velocity, but could also be due to extreme mass, or perhaps some other unknown laws of nature.

Extreme velocity and distance would also imply immense power output, which lacked explanation, and conflicted with the traditional and predominant Steady State theory of the universe.

The small sizes were confirmed by interferometry and by observing the speed with which the quasar as a whole varied in output, and by their inability to be seen in even the most powerful visible light telescopes as anything more than faint starlike points of light.

But if they were small and far away in space, their power output would have to be immense, and difficult to explain. Equally if they were very small and much closer to our galaxy, it would be easy to explain their apparent power output, but less easy to explain their redshifts and lack of detectable movement against the background of the universe.

Schmidt noted that redshift is also associated with the expansion of the universe, as codified in Hubble's law.

If the measured redshift was due to expansion, then this would support an interpretation of very distant objects with extraordinarily high luminosity and power output, far beyond any object seen to date.

This extreme luminosity would also explain the large radio signal. Schmidt concluded that 3C could either be an individual star around 10km wide within or near to our galaxy, or a distant active galactic nucleus.

He stated that a distant and extremely powerful object seemed more likely to be correct. Schmidt's explanation for the high redshift was not widely accepted at the time.

A major concern was the enormous amount of energy these objects would have to be radiating, if they were distant.

In the s no commonly-accepted mechanism could account for this. The currently accepted explanation, that it was due to matter in an accretion disc falling into an supermassive black hole, was only suggested in by Salpeter and Yakov Zel'dovich , [18] and even then it was rejected by many astronomers, because the existence of black holes was still widely seen as theoretical and too exotic, in the s, and because it was not yet confirmed that many galaxies including our own have supermassive black holes at their center.

The strange spectral lines in their radiation, and the speed of change seen in some quasars, also suggested to many astronomers and cosmologists that the objects were comparatively small and therefore perhaps bright, massive and not far away; accordingly that their redshifts were not due to distance or velocity, and must be due to some other reason or an unknown process, meaning that the quasars were not really powerful objects nor at extreme distances, as their redshifted light implied.

A common alternative explanation was that the redshifts were caused by extreme mass gravitational redshifting explained by general relativity and not by extreme velocity explained by special relativity.

Various explanations were proposed during the s and s, each with their own problems. It was suggested that quasars were nearby objects, and that their redshift was not due to the expansion of space general relativity but rather to light escaping a deep gravitational well special relativity.

This would require a massive object, which would also explain the high luminosities. However a star of sufficient mass to produce the measured redshift would be unstable and in excess of the Hayashi limit.

One strong argument against them was that they implied energies that were far in excess of known energy conversion processes, including nuclear fusion.

There were some suggestions that quasars were made of some hitherto unknown form of stable antimatter regions and that this might account for their brightness.

The uncertainty was such that even as late as , it was stated that "one of the few statements [about Active Galactic Nuclei] to command general agreement has been that the power supply is primarily gravitational", [25] with the cosmological origin of the redshift being taken as given.

Eventually, starting from about the s, many lines of evidence including the first X-Ray space observatories , knowledge of black holes and modern models of cosmology gradually demonstrated that the quasar redshifts are genuine, and due to the expansion of space , that quasars are in fact as powerful and as distant as Schmidt and some other astronomers had suggested, and that their energy source is matter from an accretion disc falling onto a supermassive black hole.

This model also fits well with other observations that suggest many or even most galaxies have a massive central black hole.

It would also explain why quasars are more common in the early universe: The accretion disc energy-production mechanism was finally modeled in the s, and black holes were also directly detected including evidence showing that supermassive black holes could be found at the centers of our own and many other galaxies , which resolved the concern that quasars were too luminous to be a result of very distant objects or that a suitable mechanism could not be confirmed to exist in nature.

By it was "well accepted" that this was the correct explanation for quasars, [27] and the cosmological distance and energy output of quasars was accepted by almost all researchers.

Hence the name 'QSO' quasi-stellar object is used in addition to "quasar" to refer to these objects, including the 'radio-loud' and the 'radio-quiet' classes.

The discovery of the quasar had large implications for the field of astronomy in the s, including drawing physics and astronomy closer together.

It is now known that quasars are distant but extremely luminous objects, so any light which reaches the Earth is redshifted due to the metric expansion of space.

Quasars inhabit the center of active galaxies, and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way , which contains — billion stars.

This radiation is emitted across the electromagnetic spectrum, almost uniformly, from X-rays to the far-infrared with a peak in the ultraviolet-optical bands, with some quasars also being strong sources of radio emission and of gamma-rays.

With high-resolution imaging from ground-based telescopes and the Hubble Space Telescope , the "host galaxies" surrounding the quasars have been detected in some cases.

Most quasars, with the exception of 3C whose average apparent magnitude is Quasars are believed - and in many cases confirmed - to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, as suggested in by Edwin Salpeter and Yakov Zel'dovich [10].

The timing and specifics of this cosmic reionization are still an open question. The newly discovered quasar adds a crucial data point: Its light shows that a significant fraction of hydrogen was still neutral million years after the Big Bang.

This favours models which predict that reionization happened comparatively late in the history of the universe. Quasars as young as this one also yield valuable information about galaxy evolution.

For instance, at almost a billion solar masses, the quasar's central black hole is comparatively massive. Explaining how such a massive black hole could have formed in such a comparatively short amount of available time is a challenge for models of supermassive black hole formation, and effectively rules out some of those models.

With those observations, the astronomers were able to identify and examine the quasar's host galaxy. Although the galaxy can be no more than million years old, it has already formed an enormous amount of dust, and heavy chemical elements.

This means it must already have formed a large amount of stars. Again, this is a challenge for models, this time for models of galaxy evolution.

Reionization, black hole evolution, galaxy evolution — even with these first observations, the newly discovered quasar has given astronomers key information about cosmic history.

Follow-up observations, as well as a search for similar quasars, are on track to put our picture of early cosmic history onto a solid footing. An in-depth description of the results can be found here.

It is regarded as one of the most successful astronomical surveys, having produced the most detailed three-dimensional maps of the universe ever made.

Now, a group of researchers led by Robertson reports the discovery of another quasar from the SDSS data. The true nature of this object was uncovered by reducing its spectrum, which was part of the program supporting photometric calibrations for the Dark Energy Survey DES.

DES is an international near-infrared survey. Its main goal is to probe the dynamics of the expansion of the universe and the growth of large-scale structures in search of important information about the mysterious phenomenon of dark energy.

This object was discovered while reducing spectra of a sample of stars being considered as spectrophotometric standards for the Dark Energy Survey," the astronomers wrote in the paper.

The quasar's absolute magnitude was found to be about 28 and its luminosity distance was estimated to be approximately This comparison allowed them to conclude that the newly confirmed QSO does not differ much from other typical quasars reported in DR 7.

Light and other radiation cannot escape from within the event horizon of a black hole, but the energy produced by a quasar is generated outside the black hole, by gravitational stresses and immense friction within the material nearest to the black hole, as it orbits and falls inward.

Central masses of 10 5 to 10 9 solar masses have been measured in quasars by using reverberation mapping. Several dozen nearby large galaxies, including our own Milky Way galaxy, that do not have an active center and do not show any activity similar to a quasar, are confirmed to contain a similar supermassive black hole in their nuclei galactic center.

Thus it is now thought that all large galaxies have a black hole of this kind, but only a small fraction have sufficient matter in the right kind of orbit at their center to become active and power radiation in such a way to be seen as quasars.

This also explains why quasars were more common in the early universe, as this energy production ends when the supermassive black hole consumes all of the gas and dust near it.

This means that it is possible that most galaxies, including the Milky Way, have gone through an active stage, appearing as a quasar or some other class of active galaxy that depended on the black hole mass and the accretion rate, and are now quiescent because they lack a supply of matter to feed into their central black holes to generate radiation.

The matter accreting onto the black hole is unlikely to fall directly in, but will have some angular momentum around the black hole that will cause the matter to collect into an accretion disc.

Quasars may also be ignited or re-ignited when normal galaxies merge and the black hole is infused with a fresh source of matter.

In fact, it has been suggested that a quasar could form when the Andromeda Galaxy collides with our own Milky Way galaxy in approximately 3—5 billion years.

In the s, unified models were developed in which quasars were classified as a particular kind of active galaxy , and a consensus emerged that in many cases it is simply the viewing angle that distinguishes them from other active galaxies, such as blazars and radio galaxies.

More than , quasars are known, most from the Sloan Digital Sky Survey. All observed quasar spectra have redshifts between 0. Applying Hubble's law to these redshifts, it can be shown that they are between million [39] and Because of the great distances to the farthest quasars and the finite velocity of light, they and their surrounding space appear as they existed in the very early universe.

The power of quasars originates from supermassive black holes that are believed to exist at the core of most galaxies. The Doppler shifts of stars near the cores of galaxies indicate that they are rotating around tremendous masses with very steep gravity gradients, suggesting black holes.

Quasars as young as this one also yield valuable information about galaxy evolution. For instance, at almost a billion solar masses, the quasar's central black hole is comparatively massive.

Explaining how such a massive black hole could have formed in such a comparatively short amount of available time is a challenge for models of supermassive black hole formation, and effectively rules out some of those models.
