Can we distinguish quark stars from neutron stars with measurements of global properties? [PDF]

open access: yesEPJ Web of Conferences, 2022
The phase state of the dense stellar matter is an exciting topic in the area of nuclear astrophysics. It may be probed by observed properties of neutron stars from, for example, the currently operating satellites (NICER, Neutron star Interior Composition

Structural thermal noise in gram-scale mirror oscillators

open access: yesNew Journal of Physics, 2012
The thermal noise associated with mechanical dissipation is a ubiquitous limitation to the sensitivity of precision experiments ranging from frequency stabilization to gravitational wave interferometry.

Potential tests of the generalized uncertainty principle in the advanced LIGO experiment

open access: yesPhysics Letters B, 2018
The generalized uncertainty principle and a minimum measurable length arise in various theories of gravity and predict Planck-scale modifications of the canonical position-momentum commutation relation.

Deep learning ensemble for real-time gravitational wave detection of spinning binary black hole mergers

open access: yesPhysics Letters B, 2021
We introduce the use of deep learning ensembles for real-time, gravitational wave detection of spinning binary black hole mergers. This analysis consists of training independent neural networks that simultaneously process strain data from multiple ...

LIGO as a probe of dark sectors [PDF]

open access: yesPhysical Review D, 2021
We show how current LIGO data is able to probe interesting theories beyond the Standard Model, particularly Dark Sectors where a Dark Higgs triggers symmetry breaking via a first-order phase transition. We use publicly available LIGO O2 data to illustrate how these sectors, even if disconnected from the Standard Model, can be probed by Gravitational ...

Binary neutron star mergers with missing electromagnetic counterparts as manifestations of mirror world

open access: yesPhysics Letters B, 2020
We suggest that the major fraction of binary mergers, which might provide gravitational wave signal detectable by LIGO/VIRGO, emerged from the hidden mirror sector.

The science case for LIGO-India [PDF]

open access: yesClassical and Quantum Gravity, 2021
Abstract The global network of gravitational-wave detectors has completed three observing runs with ∼50 detections of merging compact binaries. A third LIGO detector, with comparable astrophysical reach, is to be built in India (LIGO-Aundha) and expected to be operational during the latter part of this decade.

The First Detection of Gravitational Waves

open access: yesUniverse, 2017
This article deals with the first detection of gravitational waves by the advanced Laser Interferometer Gravitational Wave Observatory (LIGO) detectors on 14 September 2015, where the signal was generated by two stellar mass black holes with masses 36

Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA

open access: yesLiving Reviews in Relativity, 2018
We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger ...
