Researchers detect first repeating radio bursts to come from distant galaxy

Distant galaxy sends out 15 high-energy radio bursts

"On Saturday, August 26 at 13:51:44 UTC we initiated observations of the well-known repeating fast radio burst FRB 121102 using the Breakthrough Listen Digital Backend with the C-band receiver at the Green Bank Telescope", astrologists wrote in The Astronomer's Telegram.

Breakthrough Listen says fast radio bursts, or FRBs, are brief, bright pulses of radio emission from distant galaxies. This unusual astronomical phenomena was first detected in 2007 by Duncan Lorimer and David Narkovic using the Parkes Telescope in Australia.

"FRB 121102 was discovered on November 2, 2012, which gives it the name (121102). As the source is going into another active state means that the origin models associated with some sort of cataclysmic events are less likely to be the case of FRB 121102", he said.

Scholz, who was not involved with the new discovery, was with McGill University when he and a team of astronomers discovered FRB 121102 to be a repeater.

While we know the general location of FRB 121102 - a dwarf galaxy about 3 billion light years away - we don't quite know yet what generates these sounds. "Moreover, FRBs are ten billion times brighter than pulsars, so the neutron star must be special, possibly very young (10-100 years old) and with a very strong magnetic field, producing much more powerful radiation than a typical pulsar".

Breakthrough Listen is a global astronomical initiative launched in 2015 by Internet investor and philanthropist Yuri Milner and cosmologist Stephen Hawking in search for evidence of technological life in the Universe. That's why Breakthrough Listen added the source to its list of targets for observation.

The FRBs at Breakthrough Life were detected by a team led by UC Berkeley Postdoctoral Researcher Dr. Vishal Gajjar, who accumulated 400 TB of data over a period of 5 hours.

"The distinctive shape that the dispersion imposes on the initial pulse is an indicator of the amount of material between us and the source, and hence an indicator of the distance to the host galaxy", Breakthrough said in its report. After the detection of the new Radio Bursts, the follow-on examinations and analysis are being encouraged, especially at higher radio frequencies. Two, whatever happened has happened across a span of years; remember, these radio waves have to travel across space to be picked up by our telescope. "Life on Earth consisted of only single-celled organisms, and it would be another billion years before even the simplest multi-cellular life began to evolve".

Breakthrough claims that whether or not FRBs eventually turn out to be signatures of extraterrestrial technology, the project is helping push the frontiers of a new and rapidly growing area of our understanding of the Universe. But proving this assumption wrong, a team of scientists in 2016 published an article in the journal Nature where they revealed about the finding of repeating radio signals, coming from FRB 121102.
