Questions and Answers

What is the newly observed behavior of the supermassive black hole?

It is releasing bursts of radiation at irregular intervals.

It is emitting periodic plumes of gas every 8.5 days. (correct)

It is rotating at a faster rate than previously thought.

It is attracting surrounding galaxies towards itself.

What is the proposed explanation for the periodic outbursts from the black hole?

The black hole is consuming a nearby star.

The black hole is being influenced by a nearby galaxy.

The black hole is experiencing internal instabilities.

The black hole is interacting with a smaller black hole orbiting it. (correct)

How do the findings challenge the conventional understanding of black hole accretion disks?

They imply that accretion disks are not as massive as previously believed.

They indicate that accretion disks rotate in the opposite direction than previously thought.

They propose that accretion disks are not composed of gas.

They suggest that accretion disks are not uniform disks of gas. (correct)
