SMSS J114447.77–430859.3 or J1144 or J1144–4308 is a very bright (unbeamed)

Southern Cross (Crux). The SkyMapper Southern Survey (SMSS) was used to ascertain its spectral properties.[2]

J1144 was identified during a search for

binary stars.[2][3] Despite being relatively bright, it had escaped classification as a quasar in earlier searches, which avoided the crowded fields near the galactic equator.[4]

After examining various data sets, the study group determined that J1144 is the most intrinsically luminous quasar known over the last ~9 Gyr of cosmic history, having a luminosity 8 times greater than 3C 273 in Virgo.[2]

According to the lead researcher Dr Christofer Onken, of the Australian National University: While black holes are themselves not visible; their gravity is so great that not even light can escape them, they are observable because of the matter that swirls around them.
