Can the Simplest Two-Field Model of Open Inflation Survive?
Misao Sasaki, Takahiro Tanaka
We investigate the quantum fluctuations of an inflaton field in a two-field model of one-bubble open inflation. One of the inflatons is assumed to be responsible for the first fals…
Quantum fluctuations and CMB anisotropies in one-bubble open inflation models
Kazuhiro Yamammoto, Misao Sasaki, Takahiro Tanaka
We first develop a method to calculate a complete set of mode functions which describe the quantum fluctuations generated in one-bubble open inflation models. We consider two class…
Post-Newtonian expansion of gravitational waves from a particle in circular orbits around a rotating black hole: Up to beyond the quadrupole formula
Hideyuki Tagoshi, Masaru Shibata, Takahiro Tanaka +1
Extending a method developed by Sasaki in the Schwarzschild case and by Shibata, Sasaki, Tagoshi, and Tanaka in the Kerr case, we calculate the post-Newtonian expansion of the grav…
Gravitational waves from a spinning particle in circular orbits around a rotating black hole
Takahiro Tanaka, Yasushi Mino, Misao Sasaki +1
Using the Teukolsky and Sasaki-Nakamura formalisms for the perterbations around a Kerr black hole, we calculate the energy flux of gravitational waves induced by a {\it spinning} p…
