2010/3/18
We derive a new acoustic black hole metric from the Abelian Higgs model. In the non-relativistic limit, while the Abelian Higgs model becomes the Ginzburg-Landau model, the metric reduces to an ordina...

Standing Shocks around Black Holes and Estimation of Outflow Rates Santabrata Das & S. K.
accretion disk black hole physics outflows
font style='font-size:12px;'>
2009/5/19
We self-consistently obtain shock locations in an accretion
flow by using an analytical method. One can obtain the spectral properties,
quasi-periodic oscillation frequencies and the outflowrates wh...

KERR BLACK HOLES BOSE INSTABILITY
font style='font-size:12px;'>
2009/4/8
Bose instability in rotating (Kerr) black holes (BH’s) consists in
exponential increase in time of small perturbations of Bose mass fields, corresponding
to superradiative, quasi bound levels. The m...
