Neural Network Guided Parameter Space Constraints for Gravitational Wave Searches from Binary Black Holes
Chetan Verma, Amit Reza, Gurudatt Gaur +2
The detection of gravitational waves (GWs) from compact binary coalescences (CBCs) using matched filtering is computationally demanding because detector data must be correlated wit…
Finite-Momentum Kinetic Corrections to Viscous Tensor Perturbations in an Expanding Universe
Nishil Savla, Gurudatt Gaur
We study tensor perturbations propagating through a viscous relativistic medium in a spatially flat FLRW universe, with particular emphasis on the correction produced by spatial fr…
Detection of Gravitational Wave Signals from Precessing Binary Black Hole Systems using Convolutional Neural Network
Chetan Verma, Amit Reza, Gurudatt Gaur +2
Current searches for gravitational waves (GWs) from black hole binaries using the LIGO and Virgo observatories are limited to analytical models for systems with black hole spins al…
Employing Deep Learning for Detection of Gravitational Waves from Compact Binary Coalescences
Chetan Verma, Amit Reza, Dilip Krishnaswamy +2
The matched filtering paradigm is the mainstay of gravitational wave (GW) searches from astrophysical coalescing compact binaries. The compact binary coalescence (CBC) search pipel…
The Science Case for LIGO-India
M. Saleem, Javed Rana, V. Gayathri +12
The global network of gravitational-wave detectors has completed three observing runs with detections of merging compact binaries. A third LIGO detector, with comparable…
A guide to LIGO-Virgo detector noise and extraction of transient gravitational-wave signals
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1135
The LIGO Scientific Collaboration and the Virgo Collaboration have cataloged eleven confidently detected gravitational-wave events during the first two observing runs of the advanc…
