Probing the Two-Temperature Paradigm: Observational Tests for the Basic Assumptions in ADAFs
Rohan Mahadevan
We calculate the flux and spectrum of synchrotron radiation produced by high energy electrons and positrons (\epm) in an advection dominated accretion flow (ADAF) around a black ho…
Explaining the spectrum from the Galactic Centre using a two temperature plasma
Rohan Mahadevan
The radio source Sagittarius A* (Sgr A*), is thought to be a supermassive black hole located at the centre of our Galaxy, that is accreting gas from the surrounding region. Using t…
Advection-Dominated Accretion around Black Holes
Ramesh Narayan, Rohan Mahadevan, Eliot Quataert
This article reviews the physics of advection-dominated accretion flows (ADAFs) and describes applications to several black hole X-ray binaries and galactic nuclei. The possibility…
Advection-Dominated Accretion Model of Sagittarius A*: Evidence for a Black Hole at the Galactic Center
Ramesh Narayan, Rohan Mahadevan, Jonathan E. Grindlay +2
Sgr A* at the Galactic Center is a puzzling source. It has a mass M=(2.5+/-0.4) x 10^6 solar masses which makes it an excellent black hole candidate. Observations of stellar winds…
Are Particles in Advection-Dominated Accretion Flows Thermal?
Rohan Mahadevan, Eliot Quataert
We investigate the form of the momentum distribution function for protons and electrons in an advection-dominated accretion flow (ADAF). We show that for all accretion rates, Coulo…
Gamma-ray Emission From Advection-Dominated Accretion Flows Around Black Holes: Application to the Galactic Center
Rohan Mahadevan, Ramesh Narayan, Julian Krolik
We calculate the flux and spectrum of γ-rays emitted by a two-temperature advection-dominated accretion flow (ADAF) around a black hole. The γ-rays are from the decay of neutral pi…
