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…

A coupled microwave-cavity system in the Rydberg-atom cavity detector for dark matter axions
M. Tada, Y. Kishimoto, M. Shibata +5
A coupled microwave-cavity system of cylindrical TM single-mode has been developed to search for dark matter axions around 10 (2.4 GHz) with the Rydberg-atom cav…
