An Ultra-Fast Outflow Causes Scientists To Lower Mass Estimates Of The Brighest Quasar In the Universe
Peering back into the early years of the universe requires scientists to make a lot of assumptions. But sometimes, we get better instruments that then allow them to either confirm or replace those assumptions. That happened recently when it came to our study of J0529, a supermassive black hole that is currently the brightest known quasar in the universe. A new paper from a massive team of researchers used the GRAVITY+ instrument on the European Southern Observatory’s (ESO’s) Very Large Telescope (VLT) Interferometer to map this unique object’s Broad Line Region (BLR), and thereby calculated a new, updated mass that is 10 times smaller than previous estimates.
