Some images from NASA’s Hubble space telescope has helped in discovery of a celestial phenomenon never observed before, trail of stars left behind by a runaway black hole barreling across the cosmos. The said black hole was initially identified as scratches in images from Hubble space telescope but later on was widely accepted as black hole by scientist community. Scientists believe that the black hole in question is tearing across the universe after being thrown out of its own galaxy. Yale university astronomer Pieter van Dokkum has stated that trail of stars seen in the wake of the said black hole is resultant of cooling of gas possible in the wake. Condensation of gas has resulted in formation of stars in the wake of the black hole says Dokkum.
Discovery of the said runaway SMBH (supermassive black hole) and its wake by Pieter van Dokkum was purely serendipitous. Dokkum documented this discovery in his new paper published in ‘The astrophysical journal letters’. The runaway SMBH is tearing across cosmos so fast that its travel from earth to moon in our solar would have ended in 14 minutes. Weight of this SMBH is 20 million times of our sun. It has left behind a 200000 light year long trail of stars, two times the diameter of our galaxy Milky Way. Most likely reason for this celestial incidence is galactic billiards involving three giant black holes. The said runaway SMBH was probably thrown out of its galaxy due to stated galactic billiards. This black hole observation is to be confirmed by observations by Chandra X-ray observatory and James Webb Space Telescope.
The celestial phenomenon that is the subject of this article was definitely not observed before but it is a widely accepted fact that a wake of shocked gas and young stars behind it can be resultant of the interaction of runaway SMBH kicked out of its galaxy with CGM (circumgalactic medium). It is believed that the said runaway SMBH escaped its galaxy on attaining a velocity larger than the escape velocity of the host galaxy. Scientists believe that a binary SMBH was formed due to the merger of two galaxies hosting SMBH and when the third SMBH entered the merger remnant one of the SMBH attained a velocity larger than the escape velocity of the host galaxy formed by an aforementioned merger of galaxies resulting in its expulsion from the host galaxy.
