Detecting Gravitational Waves in Data with Non-Gaussian Noise

Searches for gravitational waves crucially depend on exact signal processing of noisy strain data from gravitational wave detectors, which are known to exhibit significant non-Gaussian behavior. Expand abstract.

Signatures of noncommutativity in bar detectors of gravitational waves

The comparison between the noncommutative length scale $\sqrt{\theta}$ and the length variation $\delta L=h L$, detected in the GW detectors indicate that there is a strong possibility to detect the noncommutative structure of space in the GW detector set up. Expand abstract.

Asymmetric accretion and thermal `mountains' in magnetized neutron star crusts

However, if strong shallow heating sources are present at low densities in the crust, as cooling observations suggest, these layers will be strongly perturbed and the resulting quadrupole could explain the observed spindown of PSR J1023+0038, and lead to observable gravitational wave signals from systems with higher...

Accretion-Induced Collapse of Dark Matter Admixed White Dwarfs -- II: Rotation and Gravitational-wave Signals

We present axisymmetric hydrodynamical simulations of accretion-induced collapse (AIC) of dark matter (DM) admixed rotating white dwarfs (WD) and their burst gravitational-wave (GW) signals. Expand abstract.

Helical phase inflation and its observational constraints

We consider a class of helical phase inflation models from the ${\cal N}=1$ supergravity where the phase component of a complex field acts as an inflaton. Expand abstract.

Gravitational wave detection beyond the standard quantum limit using a negative-mass spin system and virtual rigidity

Gravitational wave detectors (GWDs), which have brought about a new era in astronomy, have reached such a level of maturity that further improvement necessitates quantum-noise-evading techniques. Expand abstract.

An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo

We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the first and second observing runs of Advanced LIGO and Advanced Virgo. Expand abstract.

Gravitational wave emission from unstable accretion discs in tidal disruption events

Gravitational waves can be emitted by accretion discs if they undergo instabilities that generate a time varying mass quadrupole. Expand abstract.
