HI Jet towards a supernova remnant
Earth and Space Sciences
A supernova explosion heralds the death of a massive star and a supernova remnant represents the heated leftover gaseous matter of this event in the neighbourhood. The supernova remnant G351.7, was discovered using GMRT by a team led by IIST. In addition, a jet of atomic hydrogen has been found emanating from a region in the supernova remnant G351.7 in a follow-up study. This is the first time that such a highly collimated HI jet from a SNR has been detected.
Caption: Image shows radio continuum emission from supernova remnant G351.6 at 325 MHz. The blue colour on the right enlarged picture depicts the atomic hydrogen. The arrows indicate direction of the jet lobes and cross shows the location of high energy gamma-ray source.
