Fast Bayesian Inference for Long-Duration Gravitational-Wave Signals in 3G detectors
Anand S. Sengupta
Third-generation (3G) gravitational-wave detectors will observe binary-neutron-star inspirals for nearly a day, so Earth's rotation becomes part of the signal rather than a negligi…
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 Compact Binary Coalescences in the Decihertz GW Band with IndIGO-D
Abhishek Sharma, Divya Tahelyani, Anand S. Sengupta +1
We present an astrophysical science-case study of IndIGO-D, a decihertz gravitational-wave mission concept, focusing on compact binary sources across the 0.1-10 Hz band bridging LI…
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…
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…
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…
Fast and faithful interpolation of numerical relativity surrogate waveforms using meshfree approximation
Lalit Pathak, Amit Reza, Anand S. Sengupta
Several theoretical waveform models have been developed over the years to capture the gravitational wave emission from the dynamical evolution of compact binary systems of neutron…
Pinpointing coalescing binary neutron star sources with the IGWN, including LIGO-Aundha
Sachin R. Shukla, Lalit Pathak, Anand S. Sengupta
LIGO-Aundha (A1), the Indian gravitational wave detector, is expected to join the IGWN and begin operations in the early 2030s. We study the impact of A1 on the accuracy of determi…
Prompt sky localization of compact binary sources using a meshfree approximation
Lalit Pathak, Sanket Munishwar, Amit Reza +1
The number of gravitational wave signals from the merger of compact binary systems detected in the network of advanced LIGO and Virgo detectors is expected to increase considerably…
Effectual gravitational-wave template banks for coalescing compact binaries using a hybrid placement algorithm
Soumen Roy, Anand S. Sengupta, Parameswaran Ajith
Recent discoveries of gravitational wave (GW) signals from astrophysical compact binary systems of neutron stars and black holes have firmly established them as prime sources for a…
