Observational constraints on the nonlinear regime of gravity with a parametrized beyond-GR gravitational waveform model
Daiki Watarai, Atsushi Nishizawa, Hiroki Takeda +2
Gravitational waves from compact binary coalescences provide unique opportunities to test general relativity (GR) in the strong-field regime. In particular, the merger phase, durin…
Constraints on Logarithmic Model Extensions of Symmetric Teleparallel Gravity
Purnendu Karmakar, Sandeep Haridasu, Atsushi Nishizawa
We address various cosmological phenomenologies in the symmetric teleparallel framework both in background and perturbation such as cosmic expansion, gravitational coupling constan…
Statistical biases in parametrized searches for gravitational-wave polarizations
Hayato Imafuku, Hiroki Takeda, Atsushi Nishizawa +2
In tests of gravity using gravitational waves (GWs), GW events analyzed are often selected based on specific criteria, particularly the signal-to-noise ratio. However, such event s…
