Formation of Supermassive Black Holes: Simulations in General Relativity
Stuart L. Shapiro
There is compelling evidence that supermassive black holes exist. Yet the origin of these objects, or their seeds, is still unknown. We discuss several plausible scenarios for form…
Collapse of a Rotating Supermassive Star to a Supermassive Black Hole: Post-Newtonian Simulations
Motoyuki Saijo, Thomas W. Baumgarte, Stuart L. Shapiro +1
We study the gravitational collapse of a rotating supermassive star (SMS) by means of a (3+1) hydrodynamical simulation in a post-Newtonian (PN) approxi- mation of general relativi…
Dynamical Bar Instability in Relativistic Rotating Stars
Motoyuki Saijo, Masaru Shibata, Thomas W. Baumgarte +1
We study by computational means the dynamical stability against bar-mode deformation of rapidly and differentially rotating stars in a post-Newtonian approximation of general relat…
Brief Comments on ``The Shapiro Conjecture, Prompt or Delayed Collapse ?'' by Miller, Suen and Tobias
Stuart L. Shapiro
Recent numerical simulations address a conjecture by Shapiro that when two neutron stars collide head-on from rest at infinity, sufficient thermal pressure may be generated to supp…
Hot, Rotating Disks In General Relativity: Collisionless Equilibrium Models
A. Katrin Schenk, Stuart L. Shapiro, Saul A. Teukolsky
We present a method for constructing equilibrium disks with net angular momentum in general relativity. The method solves the relativistic Vlasov equation coupled to Einstein's equ…
Binary Neutron Stars in Quasi-Equilibrium Circular Orbit: A Fully Relativistic Treatment
Thomas W. Baumgarte, Stuart L. Shapiro, Gregory B. Cook +2
We present a numerical scheme that solves the initial value problem in full general relativity for a binary neutron star in quasi-equilibrium. While Newtonian gravity allows for a…
