,Black Hole Solutions of Einstein’s Equations an Overview,of Penrose Cosmic Censorship hypothesis as the most essential principle underlying black hole astrophysics is also discussed. It is argued that from an astrophysicist’s point of view the two parameter family of Kerr black holes is for the moment sufficient for accretion modeling.

Water Mega Masers in NGC4258,mechanisms of astronomical masers, including mega masers, do not have any direct relations to the relativity or black hole physics. Because of the high brightness and spot-like features of astronomical masers, they are very excellent probes of the positions and movements of masing objects. The water

However, there are many uncertainties regarding the fate of stellar material after the tidal disruption. It is not clear whether the stell

The importance of long term monitoring at different spectral regions will be discussed in connection with the current theoretical models for blazar radiation.

High Energy Gamma-Ray Emission from Blazars: ,,(CGRO). EGRET has detected high energy γ-ray emission at energies greater than 100 MeV from more that 50 blazars. These sources show inferred isotropic luminosities as large as 3 × 10. ergs s.. One of the most remarkable characteristics of the EGRET observations is that the γ-ray luminosity often do

While trying to find the cause of radio noise of the transatlantic telephonic conversations, Jansky found that most of the radio static noise were from thunderstorms. But even when there were no storm, the faint noise persisted and it was found to be mostly coming from the direction of th

High Proper Motion Stars in the Vicinity of Sgr A*: Evidence for a Supermassive Black Hole at the Cult to prove that one exists. The challenge is to assess the distribution of matter in the few central parsecs of the Galaxy. Assuming that gravity is the dominant force, the motion of the stars and gas in the vicinity of the putative black hole offers a robust method for accomplishing this task, by
