In a discovery that astronomers are calling a \u201ctruly extraordinary\u201d find, a powerful \u201cspace laser\u201d mega-beam has been detected from across the cosmos<\/a>.<\/p>\n

The remarkable discovery was made by astronomers using the MeerKAT radio telescope<\/a> in South Africa, by a team led by researchers from the University of Pretoria.<\/p>\n

The team says it has detected a distant hydroxyl megamaser with the aid of MeerKAT\u2019s powerful capabilities, along with powerful gravitational lensing<\/a>, within a merging galaxy<\/a> located an astounding 8 billion light-years from Earth. The discovery, the team says, marks astronomers\u2019 entry into a new and exciting frontier in radio astronomy.<\/p>\n

\u201cThis system is truly extraordinary,\u201d said Dr. Thato Manamela, a postdoctoral researcher with the University of Pretoria and first author of a recent study detailing the findings.<\/p>\n

A Hydroxyl \u201cSpace Laser\u201d is Spotted <\/p>\n

These novel \u201cspace lasers\u201d are actually a very bright variety of radio emissions<\/a> that are generated when hydroxyl molecules present in gassy merging galaxies collide. The resulting hydroxyl megamasers produced by these powerful events stimulate hydroxyl molecules, which<\/p>\n

Significantly boosts the radio emissions these cosmic regions produce.<\/p>\n

Astronomers liken them to \u201cspace lasers\u201d because the conditions that give rise to such phenomena are very similar to how scientists produce lasers on Earth, although carried across much greater light wavelengths\u2014clocking in at around 18 centimeters\u2014than those detectable by the human eye.<\/p>\n

The resulting light is extremely bright, giving rise to what astronomers call a megamaser, which is visible across extremely great astronomical distances.<\/p>\n

HATLAS Shrugged <\/p>\n

The recent detections focused on a new system astronomers have designated HATLAS J142935.3\u2013002836. Located more than 8 billion light-years away, this system is so far away<\/a> that the emissions observed during the recent MeerKAT detections originally occurred when the Universe was less than half its present age.<\/p>\n

Presently, HATLAS J142935.3\u2013002836 is recognized as not only the most distant luminous object ever observed by astronomers, but also one so awesomely powerful that an entirely new classification of object, which astronomers now call a gigamaser, has been proposed for it.<\/p>\n

One of the most remarkable aspects of the discovery is the surprising strength of HATLAS J142935.3\u2013002836\u2019s signal, despite its incredible distance from Earth. Still, astronomers would not have succeeded in detecting it had it not been for the combination of MeerKAT\u2019s sensitive capabilities and the astrophysical phenomenon of gravitational lensing.<\/p>\n

First theorized by Einstein, gravitational lensing occurs when concentrations of matter across the universe bend light between its origin point and Earth, which grants astronomers an unprecedented ability to detect objects from across the cosmos.<\/p>\n

An \u201cExtraordinary\u201d Discovery<\/p>\n

Dr. Manamela said that he and his team were very surprised to spot such a luminous object beaming toward Earth from so far away.<\/p>\n

\u201cWe are seeing the radio equivalent of a laser halfway across the universe,\u201d Manamela said in a statement. \u201cNot only that, during its journey to Earth, the radio waves are further amplified by a perfectly aligned, yet unrelated foreground galaxy.\u201d<\/p>\n

\u201cThis galaxy acts as a lens, the way a water droplet on a window pane would, because its mass curves the local space-time,\u201d Manamela added. \u201cSo we have a radio laser passing through a cosmic telescope before being detected by the powerful MeerKAT radio telescope\u2014altogether enabling a wonderfully serendipitous discovery.\u201d<\/p>\n

While MeerKAT is specially designed to make such detections, researchers still have to carefully process vast amounts of information it gathers, which also must be properly calibrated before collection. State-of-the-art algorithms<\/a> and other advanced computational processing methods enable the kinds of discoveries<\/a> Manamela\u2019s team has made.<\/p>\n

The result of this elaborate process is \u201ca powerful demonstration of what MeerKAT can do when paired with advanced computational infrastructure, fit-for-purpose data processing pipelines, and highly-trained software support personnel,\u201d according to Professor Roger Deane, Director of the Inter-University Institute for Data Intensive Astronomy (IDIA) and a Professor at the Universities of Cape Town and Pretoria.<\/p>\n

Manamela says that what he and his team are now doing only marks the beginning of the discoveries they hope to unravel in the years ahead.<\/p>\n

Fundamentally, what the team has accomplished\u2014in addition to highlighting South Africa\u2019s role in radio astronomy and the partnerships between IDIA and SARAO that are propelling MeerKAT\u2019s discoveries\u2014is a new means of studying the universe by enhancing our ability to detect some of the rarest phenomena in the cosmos.<\/p>\n

\u201cThis synergistic combination empowers young South African scientists, like Dr. Manamela, to lead cutting-edge science and compete with the best in the world,\u201d Deane said, who was also a co-author on the recent study.<\/p>\n

\u201cWe don\u2019t want to find just one system\u2014we want to find hundreds to thousands,\u201d Manamela added.<\/p>\n

The team\u2019s recent study<\/a>, \u201cMeerKAT discovery of a high-redshift strongly-lensed hydroxyl gigamaser,\u201d appeared at the preprint server arXiv.org and has been accepted for publication in\u00a0Monthly Notices of the Royal Astronomical Society Letters.<\/p>\n
