Unraveling information about supranuclear-dense matter from the complete binary neutron star coalescence process using future gravitational-wave detector networks
Anna Puecher, Tim Dietrich, Ka Wa Tsang +4
Gravitational waves provide us with an extraordinary tool to study the matter inside neutron stars. In particular, the postmerger signal probes an extreme temperature and density r…
Beyond general relativity: designing a template-based search for exotic gravitational wave signals
Harsh Narola, Soumen Roy, Anand S. Sengupta
Accurate waveform models describing the complete evolution of compact binaries are crucial for the maximum likelihood detection framework, testing the predictions of General Relati…
Testing general relativity using higher-order modes of gravitational waves from binary black holes
Anna Puecher, Chinmay Kalaghatgi, Soumen Roy +4
Recently, strong evidence was found for the presence of higher-order modes in the gravitational wave signals GW190412 and GW190814, which originated from compact binary coalescence…
Nonorthogonal wavelet transformation for reconstructing gravitational wave signals
Soumen Roy
Detections of gravitational-wave signals from compact binary coalescences have enabled us to study extreme astrophysical phenomena and explore fundamental physics. A crucial requis…
Probing the post-Minkowskian approximation using recursive addition of self-interactions
Soumendra Kishore Roy, Ratna Koley, Parthasarathi Majumdar
We address the problem of deriving the post-Minkowskian approximation, widely used in current gravitational wave literature by investigating a possible deduction out of the recursi…
Kinematics of Two-particle Scattering in Black Hole Backgrounds
Soumendra Kishore Roy, Ratna Koley, Parthasarathi Majumdar
We show that particle scattering in general curved backgrounds entails {\it six} independent, kinematical Mandelstam-like invariants, instead of the two in flat spacetime. Spacetim…
