Relativistic stars in degenerate higher-order scalar-tensor theories after GW170817
Tsutomu Kobayashi, Takashi Hiramatsu
We study relativistic stars in degenerate higher-order scalar-tensor theories that evade the constraint on the speed of gravitational waves imposed by GW170817. It is shown that th…
Anti-screening of the Galileon force around a disk center hole
Hiromu Ogawa, Takashi Hiramatsu, Tsutomu Kobayashi
The Vainshtein mechanism is known as an efficient way of screening the fifth force around a matter source in modified gravity. This has been verified mainly in highly symmetric mat…
Detecting a stochastic background of gravitational waves in the presence of non-Gaussian noise: A performance of generalized cross-correlation statistic
Yoshiaki Himemoto, Atsushi Taruya, Hideaki Kudoh +1
We discuss a robust data analysis method to detect a stochastic background of gravitational waves in the presence of non-Gaussian noise. In contrast to the standard cross-correlati…
Detecting a gravitational-wave background with next-generation space interferometers
Hideaki Kudoh, Atsushi Taruya, Takashi Hiramatsu +1
Future missions of gravitational-wave astronomy will be operated by space-based interferometers, covering very wide range of frequency. Search for stochastic gravitational-wave bac…
