Not a certainty of course but a sensible opening position. One suggestion was that the  30 Aug 2017 The location of FRB 121102 has already been previously traced to a dwarf galaxy about 3 billion light years away, but what exactly might be sending out such strong signals from there remains a mystery. Jansky Very Large  In radio astronomy, a fast radio burst (FRB) is a high-energy astrophysical phenomenon of unknown origin manifested as a transient radio pulse lasting only a few milliseconds. Additional fully These observations may indicate FRB 121102 is currently in a heightened activity state [Law et al. In 2016, astronomers pinpointed the location of the bursts on our sky's dome, associating them with a dwarf galaxy about 3 billion light-years from Earth. 1-1"  The FRB 121102 host galaxy is resolved, revealing a bright star-forming region located in the outskirts of the irregular, low-metallicity dwarf galaxy. 2016).

In 2016, astronomers pinpointed the location of the bursts on our sky's dome, associating them with a dwarf galaxy about 3 billion light-years from Earth. Gemini Observatory/AURA/NRC/NSF/NRAO. An observation in 2012 of a fast radio burst (FRB 121102) in the direction of Auriga in the northern hemisphere using the Arecibo radio telescope confirmed the extragalactic origin of fast radio pulses by an effect known as plasma dispersion. Gajjar says that the repeating nature and current state of heightened activity for FRB 121102 does  FRB 121102 -- radio Burst. Thanks to FRB 121102's persistent hiccups (it's been observed to flash more than 150 times), we now know that its source lies in a small galaxy 3 billion  FRB 121102. To make things stranger still, the 15 new bursts detected by the Breakthrough Listen initiative were at frequencies of around 7 GHz, which is higher  26 May 2017 The star-forming region where FRB 121102 originates is located on the outskirts of the galaxy, 6,200 light-years from the core. Vishal Gajjar observed the location  4 Jan 2017 But astronomers got lucky when they found a particular burst known as FRB 121102: it is the only one known to repeat, meaning multiple radio bursts have been detected coming from the same location in the sky. (Last month, for example, scientists with Breakthrough  Jan 4, 2017 The latest work, published on 4 January in Nature, is the sharpest look yet at the home of a fast radio burst known as FRB 121102.
