Particle creation in gravitational collapse to a horizonless compact object
Tomohiro Harada, Vitor Cardoso, Daiki Miyata
Black holes (BHs) play a central role in physics. However, gathering observational evidence for their existence is a notoriously difficult task. Current strategies to quantify the…
Effect of Inhomogeneity on Primordial Black Hole Formation in the Matter Dominated Era
Takafumi Kokubu, Koutarou Kyutoku, Kazunori Kohri +1
We investigate the effect of inhomogeneity on primordial black hole formation in the matter dominated era. In the gravitational collapse of an inhomogeneous density distribution, a…
Linear stability analysis of a rotating thin-shell wormhole
Naoki Tsukamoto, Takafumi Kokubu
We cut and paste two Banados-Teitelboim-Zanelli (BTZ) spacetimes at a throat by the Darmois-Israel method to construct a rotating wormhole with a thin shell filled with a barotropi…
