Searching for gravitational wave echoes from black hole binary events in the third observing run of LIGO, Virgo, and KAGRA collaborations
Nami Uchikata, Tatsuya Narikawa, Hiroyuki Nakano +3
Gravitational wave echo signals have been proposed as evidence for the modification of the spacetime structure near the classical event horizon. These signals are expected to occur…
Detectability of bigravity with graviton oscillations using gravitational wave observations
Tatsuya Narikawa, Koh Ueno, Hideyuki Tagoshi +3
The gravitational waveforms in the ghost-free bigravity theory exhibit deviations from those in general relativity. The main difference is caused by graviton oscillations in the bi…
Constraint on the cosmological f(R) model from the multipole power spectrum of the SDSS luminous red galaxy sample and prospects for a future redshift survey
Kazuhiro Yamamoto, Gen Nakamura, Gert Huetsi +2
A constraint on the viable f(R) model is investigated by confronting theoretical predictions with the multipole power spectrum of the luminous red galaxy sample of the Sloan Digita…
