Black Hole Event Horizons and X-ray Nova Luminosities - Update
Recently, Narayan, Garcia and McClintock showed that there is a difference in the quiescent luminosities of black hole and neutron star x-ray nova: when the...
Despite ~50 years of compact object studies in the Galaxy, the physics of relativistic jet launching remains an active and open field of research. There has...
Black Hole Mass estimates in nearby AGN from Host-Bulge Properties
In this work we present the results of an optical photometric study performed to seven nearby AGN that were selected with the SDSS-DR5 database. Surface...
Studies of black holes are at a threshold. There is compelling evidence for the existence of both stellar-mass and supermassive black holes, and research is now...
Black Holes Really are Black: New Evidence From Chandra
We have used the Chandra X-ray Observatory to observe the following six black hole X-ray transients in quiescence: GRO J0422+32 (orbital period Porb=5.1 hr)...
