Testing general relativity with amplitudes of subdominant gravitational-wave modes
Ish Gupta, Purnima Narayan, Lionel London +2
We present an improved subdominant-mode amplitude (SMA) test of general relativity (GR), which probes amplitude-level deviations in the higher-order modes of gravitational-wave (GW…
Confronting general relativity with principal component analysis: Simulations and results from GWTC-3 events
Parthapratim Mahapatra, Sayantani Datta, Ish Gupta +10
We present a comprehensive assessment of multiparameter tests of general relativity (GR) in the inspiral regime of compact binary coalescences using principal component analysis (P…
Effect of Type II Strong Gravitational Lensing on Tests of General Relativity
Purnima Narayan, Nathan K. Johnson-McDaniel, Anuradha Gupta
Gravitational wave (GW) observations of binary black hole (BBH) coalescences provide a unique opportunity to test general relativity (GR) in the strong-field regime. To ensure the…
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…
Effect of Ignoring Eccentricity in Testing General Relativity with Gravitational Waves
Purnima Narayan, Nathan K. Johnson-McDaniel, Anuradha Gupta
Detections of gravitational waves emitted from binary black hole coalescences allow us to probe the strong-field dynamics of general relativity (GR). One can compare the observed g…
Relating the curvature of De Sitter Universe to Open Quantum Lamb Shift Spectroscopy
Hardik Bohra, Sayantan Choudhury, Prashali Chauhan +3
In this paper, we explore the connection between the curvature of the background De Sitter space-time with the spectroscopic study of entanglement of two atoms. Our set up is in th…
