New observations of the Milky Way's central black hole

Astrophysics

New observations of the supermassive black hole at the center of the Milky Way indicate it is not destroying everything in its vicinity. The findings suggest a more complex interaction between the black hole and surrounding matter than previously assumed. It is tempting to stick with the standard model of indiscriminate destruction, as that aligns with our general understanding of these objects. However, suppose the interaction is governed by variables we haven't fully weighted. If the environment is more stable than predicted, we might be looking at a fundamental gap in how we model matter interactions at the galactic center.

Does this stability apply to the S-stars too... or is it only referring to the accretion disk? I'm wondering if those extreme orbital velocities actually conflict with this new view of the environment...

If we assume the stability is a localized effect of the accretion flow, wouldn't that be consistent with the S-star orbits? It is possible the destruction we expect only applies to matter crossing the innermost stable circular orbit, not objects in wider elliptical paths.

This comes right as they're upgrading the EHT arrays. We need to consider if these stable interactions are actually just artifacts of higher resolution imaging that we simply didn't have a few years ago.

Given the history of resolution-based discoveries that later turned out to be calibration errors, do we have independent verification from a different wavelength yet?

The OP is correct about the modeling gap. The presence of Magnetically Arrested Disks (MAD) provides a mechanism where magnetic pressure halts the inflow of matter, preventing the indiscriminate consumption usually assumed.

Similar magnetic flux patterns were noted in the M87* observations. This suggests the phenomenon isn't an anomaly of our own galaxy but a common feature of supermassive black holes.

probably just a function of the hole's spin rate.
