Quadrupolar power radiation by a binary system in a hyperbolic encounter on de Sitter background
Michael Blanc, Philippe Jetzer, Shubhanshu Tiwari
The present cosmological model and the surveys favor the universe with a small but positive cosmological constant , which accounts for dark energy and causes an exponential expa…
Measuring gravitational wave memory with LISA
Henri Inchauspé, Silvia Gasparotto, Diego Blas +3
Gravitational wave (GW) astronomy has revolutionized our capacity to explore nature. The next generation of observatories, among which the space-borne detector Laser Interferometer…
Detectability of eccentric binary black holes with PyCBC and cWB pipelines during the third observing run of LIGO-Virgo-KAGRA
Bhooshan Gadre, Kanchan Soni, Shubhanshu Tiwari +3
Detecting binary black hole (BBH) mergers with quantifiable orbital eccentricity would confirm the existence of a dynamical formation channel for these binaries. The current state-…
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…
Enhancing Gravitational Wave Parameter Estimation with Non-Linear Memory: Breaking the Distance-Inclination Degeneracy
Yumeng Xu, Maria Rosselló-Sastre, Shubhanshu Tiwari +5
In this study, we investigate the role of the non-linear memory effect in gravitational wave (GW) parameter estimation, particularly we explore its capability to break the degenera…
Measuring eccentricity and gas-induced perturbation from gravitational waves of LISA massive black hole binaries
Mudit Garg, Andrea Derdzinski, Shubhanshu Tiwari +2
We assess the possibility of detecting both eccentricity and gas effects (migration and accretion) in the gravitational wave (GW) signal from LISA massive black hole binaries (MBHB…
