Supermassive Black Hole Feedback
Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped by the energy injection from accreting supermassive black holes (SMBHs). However, it is unclear how

Weighing supermassive black holes [PDF]
A study suggests that the gas clouds in the vicinity of rapidly accreting supermassive black holes are distributed in a planar distribution, impacting the estimation of the mass of the black hole based on the motion of these clouds.

Powerful Radio Sources as Probes of Black Hole Physics
Powerful jetted radio sources for which the luminosity in directed kinetic energy has been empirically determined, independent of assumptions, are considered.

Evolution of Supermassive Black Holes [PDF]
Supermassive black holes (SMBHs) are nowadays believed to reside in most local galaxies, and the available data show an empirical correlation between bulge luminosity - or stellar velocity dispersion - and black hole mass, suggesting a single mechanism for assembling black holes and forming spheroids in galaxy halos. The evidence is therefore in favour

Supermassive Black Hole Growth in Hierarchically Merging Nuclear Star Clusters
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue to low stellar masses.

Black hole shadow with a cosmological constant for cosmological observers
We investigate the effect of the cosmological constant on the angular size of a black hole shadow. It is known that the accelerated expansion which is created by the cosmological constant changes the angular size of the black hole shadow for static ...

We investigate the strong gravitational lensing effects of various supermassive compact objects for the static and spherically symmetric hairy black hole by gravitational decoupling.

A FUNDAMENTAL EQUATION FOR SUPERMASSIVE BLACK HOLES [PDF]
We developed a theoretical model that is able to give a common origin to the correlations between the mass M• of supermassive black holes and the mass, velocity dispersion, kinetic energy and momentum parameter of the corresponding host galaxies. Our model is essentially based on the transformation of the angular momentum of the interstellar material,
