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…
