Does the newly found orientation of Sgr A* match the theory that the Fermi bubbles might have been caused by jets?

The video discusses exactly this question around the 15 minute mark. The newly published results seem to favour an inclination between the spin axis of Sgr A* and the ...

Why is the ring in this simulation of Sgr A* off center?

The photon ring around a non-spinning Schwarzschild black hole is perfectly circular and centered on the black hole. The photon ring around a spinning Kerr black hole is almost circular (except for ...

Will the first Event Horizon Telescope image of the Milky Way's black hole Sgr A* just be another lumpy orange donut?

Yes. See today's press release from the Event Horizon Telescope. The image is remarkably similar to M87, but note that this a time-averaged composite over about 10 hours, because the emission from the ...
