Stochastic template banks for GW searches using low-discrepancy sequences
Tarun Kumar, Anand S. Sengupta
Matched filtering remains the most sensitive method for detecting gravitational waves from compact binary coalescences. The efficiency of such searches depends on how well a discre…
Probing missing physics from inspiralling compact binaries via time-frequency tracks
Debtroy Das, Soumen Roy, Anand S. Sengupta +1
The orbital evolution of binary black hole (BBH) systems is determined by the component masses and spins of the black holes and the governing gravity theory. Gravitational wave (GW…
IndIGO-D: Probing Compact Binary Coalescences in the Decihertz GW Band
Abhishek Sharma, Divya Tahelyani, Anand S. Sengupta +1
We study IndIGO-D, a decihertz gravitational-wave mission concept, focusing on a specific configuration in which three spacecraft fly in formation to form an L-shaped interferomete…
Rapid parameter estimation with the full symphony of compact binary mergers using meshfree approximation
Abhishek Sharma, Lalit Pathak, Soumen Roy +1
We present a fast Bayesian inference framework to address the growing computational cost of gravitational-wave parameter estimation. The increased cost is driven by improved broadb…
Accelerated parameter estimation of supermassive black hole binaries in LISA using a meshfree approximation
Abhishek Sharma, Anand S. Sengupta, Suvodip Mukherjee
The Laser Interferometer Space Antenna (LISA) will be capable of detecting gravitational waves (GWs) in the milli-Hertz band. Among various sources, LISA will detect the coalescenc…
