Unveiling J0529: How Blazing Outflows Shrinked the Universe’s Brightest Quasar Mass by 10x
Revisiting a Cosmic heavyweight J0529 stands as the Universe’s brightest known quasar, a blazing beacon powered by a supermassive black hole that formed not long after the Big Bang. In 2024, estimates pegged its mass at about 10 billion solar masses, a figure that underscored how rapidly supermassive black holes could grow in the early…

New GRAVITY+ Reveal Shrinks Brightest Quasar Mass by Order of Magnitude
New measurements by GRAVITY+ challenge long-held estimates of the Universe’s brightest quasar Peering back to the early universe often requires scientists to rely on indirect methods and assumptions. A recent study, however, leveraged the GRAVITY+ instrument on the European Southern Observatory’s Very Large Telescope Interferometer (ESO VLT) to map the Broad Line Region (BLR) of…
