Theoretical modeling of approximate universality of tidally deformed neutron stars
Takuya Katagiri, Gowtham Rishi Mukkamala, Kent Yagi
Quasi-universal relations are known to exist among various neutron star observables that do not depend sensitively on the underlying nuclear matter equations of state. For example,…
Tidal response beyond vacuum General Relativity with a canonical definition
Takuya Katagiri, Vitor Cardoso, Tact Ikeda +1
Tidal effects on compact objects provide profound theoretical insights into the structure of the field equations, and are wonderful probes of the equation of state of matter, the n…
On relativistic dynamical tides: subtleties and calibration
Takuya Katagiri, Kent Yagi, Vitor Cardoso
The response of astrophysical compact objects to external tidal fields carries valuable information on the nature of these objects, on the equation of state of matter, and on the u…
Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
