Biological air filtration is a promising technique for air-quality control in closed environments in space and on Earth, and it offers several advantages over...
Orientation effects are believed to be important in sources which harbor relativistic jets in their nuclei. BL Lac type objects are interpreted as a type of...
We review recent results that indicate that black hole entropy and other thermodynamical quantities can be consistently computed in LQG and that the results are...
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...
