Detecting quasars from the early Universe

#aeronautics #aerospace #electrical #satellites

Quasars are supermassive black holes that are accreting matter at very high rates and thus growing rapidly. As such black holes grow, the infalling matter releases an extraordinary amount of radiation, which makes quasars visible even at extremely large distances - the most distant (i.e. the highest-redshift) quasar we know of lies more than 13 billion light years away! This talk will provide an overview of the science done with these distant quasars, with a particular focus on the technical advancements that have enabled the detection of their light, emanating right from the beginning of the Universe.
