Crunch from AdS bubble collapse in unbounded potentials
Kaloian D. Lozanov, Misao Sasaki
We consider a scalar field theory with a Minkowski false vacuum and an unbounded (or very deep) true vacuum. We show compelling evidence that an AdS bubble of vanishing total energ…
Probing Primordial Black Hole Scenarios with Terrestrial Gravitational Wave Detectors
Guillem Domènech, Misao Sasaki
It is possible that primordial black holes consitute (or consituted) a significant fraction of the energy budget of our universe. Terrestrial gravitational wave detectors offer the…
Gravitational wave hints black hole remnants as dark matter
Guillem Domènech, Misao Sasaki
The end state of Hawking evaporation of a black hole is uncertain. Some candidate quantum gravity theories, such as loop quantum gravity and asymptotic safe gravity, hint towards P…
Gravitational Waves Induced by Scalar Perturbations with a Lognormal Peak
Shi Pi, Misao Sasaki
We study the stochastic gravitational wave (GW) background induced by the primordial scalar perturbation with the spectrum having a lognormal peak of width at . We deriv…
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…
