Gravitational eddies across the galaxy?
I read about natural gravitational eddies that travel in a wave that black holes have. They also have a strong magnetic field. Does those eddies follow magnetic field lines of the rotating black hole? ...

What will be the eventual result of the Milky Ways future mergers?
I am wondering, after the Milky Way merges with Andromeda and other near by dwarf galaxies and globular clusters, will it then merge with galaxies in the Virgo cluster and even Laniakea? And if so ...

Does the (relative) distance of the photon sphere from the center of a black hole vary according its mass?
I know that the photon circle or photon sphere is located at around 1.5 times the radius of the Schwarzschild event horizon, but wouldn't it be comparatively further out for smaller black holes?
After ...

How many massive black holes exist in AGN-type galaxies?
Most galaxies have a massive (i.e., $m \gtrsim 10^5$ M$_{\odot}$) black hole in their center.
Is it known 1) theoretically and 2) observationally what fraction of these massive black holes (maybe as a ...

What is the effect of extinction in the accretion disk for black hole mass determination?
I've created a basic model of the accretion disk (AD) by summing up blackbodies following the temperature profile of the AD according to Shakura & Sunyaev (1973) (extensively used in the ...

Details of the M87 Active Galactic Nucleus -- questions of scale
This video describes a scale model of the M87 SMBH (somewhat distorted to live in flat space and for other practical reasons) in which the Schwarzschild radius appears to be scaled to about 10cm, with ...

How spaghettification is possible at the Event Horizon of a supermassive black hole?
if gravity is too strong then it will break a object apart as gravity is strong enough to break the chemical composition of object why we consider "Spaghettification" relevant in this case ?
