Black holes burp radiation after galaxy formation!

b. West Field Infrared Survery Explorer
c. Width Field Infrated Survery Explorer
d. None of the above

ANSWER: Wide Field Infrared Survey Explorer
For the first time, astronomers have documented the process through which radiation is expelled from black holes- holding the key to how galaxies are formed using the WISE telescope.
  • The NASA’s Wide-field Infrared Survey Explorer (WISE) telescope studied how supermassive black holes – concentrations of mass the size of hundreds of thousands or even millions of suns, with gravity so powerful even light cannot escape – exist in the centres of most galaxies.
  • When an object is absorbed by a black hole, not all of the contents are consumed – instead it emits a vast “belch” of intense radiation,
  • This is a blinding bright whip of energy known as a tidal disruption flare, which wipes out everything in its path.
  • Using images from the WISE telescope, launched in 2009, which can measure the infrared emissions of cosmic dust, the US scientists have found at least three black holes surrounded by the radiation-charged cosmic dust
  • Chinese have found another one.
  • “This is the first time we have clearly seen the infrared light echoes from multiple tidal disruption events,” say researchers
  • Belches create new stars and form the shape of the galaxy
  • Scientists say this is how mechanics of process operated while the universe was first formed 14 billion years ago
