Gravitational-wave constraints on scalar-tensor gravity from a neutron star and black-hole binary GW200115
Hiroki Takeda, Shinji Tsujikawa, Atsushi Nishizawa
In nonminimally coupled theories where a scalar field is coupled to the Ricci scalar, neutron stars (NSs) can have scalar charges through an interaction with matter mediated by gra…

Sagnac-type neutron displacement-noise-free interferometeric gravitational-wave detector
Yuki Kawasaki, Shoki Iwaguchi, Tomohiro Ishikawa +13
The detection of low-frequency gravitational waves on Earth requires the reduction of displacement noise, which dominates the low-frequency band. One method to cancel test mass dis…
