The interior structure of astronomically realistic rotating black holes 2. Uncharged black holes
The interior structure black holes
2011/1/13
An exact solution is obtained for the interior structure of a uncharged rotating black hole that accretes a collisionless fluid. The solutions are conformally stationary, axisymmetric, and separable. ...
Scalar models for the generalized Chaplygin gas and the structure formation constraints
Scalar models generalized Chaplygin gas structure formation constraints
2010/11/9
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark
energy. It is characterized by a fluid with an equation of state p = −A/ . It can be obtained from a ge...
Evolution of gaseous disk viscosity driven by supernova explosion. II. Structure and emissions from star-forming galaxies at high redshift
gaseous disk viscosity driven supernova explosion
2011/1/10
(Abridged) High redshift galaxies are undergoing intensive evolution of dynamical structure and morphologies. We incorporate the feedback into the dynamical equations through mass dropout and angular ...
Topology of large scale structure as test of modified gravity
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The genus of the iso-density contours is a robust measure of the topology of large-scale structure, and relatively insensitive to galaxies biasing and redshift-space distortions. We show that the grow...
The Structure of the β Leonis Debris Disk
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/22
We combine nulling interferometry at 10 {\mu}m using the MMT and Keck Telescopes with spectroscopy, imaging, and photometry from 3 to 100 {\mu}m using Spitzer to study the debris disk around {\beta} L...
