The Galactic Center massive black hole and nuclear star cluster
R Genzel, F Eisenhauer, S Gillessen - Reviews of modern physics, 2010 - APS
The Galactic Center is an excellent laboratory for studying phenomena and physical
processes that may be occurring in many other galactic nuclei. The center of our Milky Way …

Hot accretion flows around black holes
Black hole accretion flows can be divided into two broad classes: cold and hot. Whereas
cold accretion flows consist of cool optically thick gas and are found at relatively high mass …

Advection-dominated accretion model of Sagittarius A*: evidence for a black hole at the Galactic center
R Narayan, R Mahadevan, JE Grindlay… - The Astrophysical …, 1998 - iopscience.iop.org
Sagittarius A*, which is located at the Galactic center, is a puzzling source. It has a mass of
M=(2.5±0.4)× 10 6 M &sun;, which makes it an excellent black hole candidate. Observations …
