Inferring spin tilts of binary black holes at formation with plus-era gravitational wave detectors
Sumeet Kulkarni, Nathan K. Johnson-McDaniel, Khun Sang Phukon +2
The spin orientations of spinning binary black hole (BBH) mergers detected by ground-based gravitational wave detectors such as LIGO and Virgo can provide important clues about the…
Numerical Relativity Estimates of the Remnant Recoil Velocity in Binary Neutron Star Mergers
Sumeet Kulkarni, Surendra Padamata, Anuradha Gupta +2
We present, for the first time, recoil velocity estimates for binary neutron star mergers using data from numerical relativity simulations. We find that binary neutron star merger…
Recoil Velocity of Binary Neutron Star Merger Remnants
Sumeet Kulkarni, Surendra Padamata, Anuradha Gupta
The LIGO-Virgo gravitational wave detectors have confidently observed 4 events involving neutron stars: two binary neutron star (BNS) mergers (GW170817 and GW190425), and two neutr…
India's first robotic eye for time domain astrophysics: the GROWTH-India telescope
Harsh Kumar, Varun Bhalerao, G. C. Anupama +35
We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illumina…
Deep Co-Added Sky from Catalina Sky Survey Images
Akshat Singhal, Varun Bhalerao, Ashish A. Mahabal +12
A number of synoptic sky surveys are underway or being planned. Typically they are done with small telescopes and relatively short exposure times. A search for transient or variabl…
Inferring spin tilts at formation from gravitational wave observations of binary black holes: Interfacing precession-averaged and orbit-averaged spin evolution
Nathan K. Johnson-McDaniel, Sumeet Kulkarni, Anuradha Gupta
Two important parameters inferred from the gravitational wave signals of binaries of precessing black holes are the spin tilt angles, i.e., the angles at which the black holes' spi…
NNETFIX: An artificial neural network-based denoising engine for gravitational-wave signals
Kentaro Mogushi, Ryan Quitzow-James, Marco Cavaglià +2
Instrumental and environmental transient noise bursts in gravitational-wave detectors, or glitches, may impair astrophysical observations by adversely affecting the sky localizatio…
Random projections in gravitational wave searches of compact binaries
Sumeet Kulkarni, Khun Sang Phukon, Amit Reza +4
Random projection (RP) is a powerful dimension reduction technique widely used in the analysis of high dimensional data. We demonstrate how this technique can be used to improve th…
