Rapid reawakening of the supermassive black hole in ESO 511-G030

Astrophysics

Astronomers observed a dormant supermassive black hole in galaxy ESO 511-G030 reawaken recently. Its brightness in ultraviolet and X-ray light increased tenfold in under three years. This timeline contradicts about fifty years of established astrophysical models regarding how gas behaves around these objects. It is a bit humbling to see our current accretion rate models outpaced so quickly, but it is also a reminder that the universe still has a few surprises left for us. There is a quiet kind of joy in realizing our rulebook is incomplete; it means we still have a lot of genuine discovery ahead of us.

Black hole revival rewrites cosmic rulebook

If we assume the disk is stable, it is similar to how we had to rewrite planetary migration theories after discovering hot Jupiters. Perhaps the rulebook is not incomplete, but we are seeing the extreme end of a distribution curve.

is this actually increased accretion or just a clearing of obscuring gas clouds?

The data shows the emergence of broad emission lines in the optical spectrum. This suggests the formation of a stable accretion disk rather than just a temporary clearing of dust.

We need to determine if this is a sustained state or a Tidal Disruption Event. A three year window is a blink in galactic time and could be a single star getting shredded.

But the UV to X-ray ratio is so specific here... it looks more like a genuine transition to an active state than a one-off event... what does that imply for the gas reservoir in the nucleus?

Does the light curve show the same exponential decay we saw with the 2015 events in similar galaxies? Or is this a linear climb?
