In January 2005, in the nucleus of the merging galaxies Arp 299, situated at nearly 150 million light years from Earth, a bright flash was detected that was considered a supernova explosion.
Astronomers first observed as a black hole ripped a star coming too close.
Up to the present time, as the scientist, his team failed to catch black holes in the first phases of their "meal" when they have already begun to destroy the star, but haven't started to eat her remains and throw the "leftovers" in the form of jets, narrow beams of plasma accelerated to near-light speeds. Instead, the black hole will form a rotating disc around it and launch superfast jets of particles from the poles of the disk at almost the speed of light.
And it took a long time for the team to get the full data on the TDE as it was all happening. The sudden injection of material produces a bright flash, followed by transient radio emissions and the formation of a jet of material that initially moves at speeds very close to that of light.
Virtually every galaxy has a supermassive black hole lurking at its center, which directly influences its development.
At its brightest, the flare outshone its parent galaxy's centre in the infrared and radio region, according to the paper in Science. The material is also being pushed outward from the poles of the disk in the form of a jet that nearly reaches the speed of light.
The scientists tracked the event with multiple radio and infrared telescopes from across the world, including the Lovell Telescope at Jodrell Bank Observatory, working as part of the European Very Long Baseline Network (EVN). Arp 299 has seen numerous stellar explosions, and has been dubbed a 'supernova factory.' This new object originally was considered to be a supernova explosion. These multiple radio antennas separated by thousands of kilometers allow the VLBA to gain an incredible resolving power - the ability to see fine detail - which is required to observe the features of an expanding object from millions of light-years away. Such events are likely common in the distant universe and studying them will advance our understanding of galaxies that developed billions of years ago.
Infrared and radio waves are those emitted beyond the visible light spectrum. It is the only way for the scientists to track one of them, but it is worth it.
Miguel Perez-Torres from Astrophysical Institute of Andalusia in Spain said.
The findings were published in the journal Science on June 14. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. STScI is operated for NASA by the Association of Universities for Research in Astronomy, Inc., in Washington.
