Causal Structures of Dynamic Black Holes
Beth A. Brown, James Lindesay
Dynamic space-times, especially those manifesting horizons, provide useful laboratories for examining how macroscopic quantum behaviors consistently co-generate gravitational pheno…
Construction of a Penrose Diagram for an Accreting Black Hole
Beth A. Brown, James Lindesay
A Penrose diagram is constructed for a spatially coherent black hole that accretes at stepwise steady rates as measured by a distant observer from an initial state described by a m…
Radial Photon Trajectories Near an Evaporating Black Hole
Beth A. Brown, James Lindesay
The radial motion of photons emitted near the horizon of a black hole that evaporates at a steady rate is examined. The space-time of the black hole is generated using non-orthogon…
Construction of a Penrose Diagram for a Spatially Coherent Evaporating Black Hole
Beth A. Brown, James Lindesay
A Penrose diagram is constructed for an example black hole that evaporates at a steady rate as measured by a distant observer, until the mass vanishes, yielding a final state Minko…
Emission Mechanisms in X-Ray Faint Galaxies
Beth A. Brown, Joel N. Bregman
Hot gas dominates the emission in X-ray luminous early-type galaxies, but in relatively X-ray faint systems, integrated X-ray emission from discrete stellar-like sources is thought…
The Effect of Environment on the X-Ray Emission from Early-Type Galaxies
Beth A. Brown, Joel N. Bregman
In order to help understand the phenomena of X-ray emission from early-type galaxies, we obtained an optically flux-limited sample of 34 early-type galaxies, observed with ROSAT. A…
