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.

Compact Binary Coalescences: Astrophysical Processes and Lessons Learned

open access: yesGalaxies, 2022
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black ...

Calibration Uncertainty for Advanced LIGO's First and Second Observing Runs [PDF]

open access: yes, 2017
Calibration of the Advanced LIGO detectors is the quantification of the detectors' response to gravitational waves. Gravitational waves incident on the detectors cause phase shifts in the interferometer laser light which are read out as intensity ...

Upper Limits on the Isotropic Gravitational-Wave Background from Advanced LIGO's and Advanced Virgo's Third Observing Run [PDF]

open access: yes, 2021
We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs

Search for Eccentric Binary Neutron Star Mergers in the first and second observing runs of Advanced LIGO

open access: yes, 2020
We present a search for gravitational waves from merging binary neutron stars which have non-negligible eccentricity as they enter the LIGO observing band. We use the public Advanced LIGO data which covers the period from 2015 through 2017 and contains $\

Correlated noise in networks of gravitational-wave detectors: subtraction and mitigation [PDF]

open access: yes, 2014
One of the key science goals of advanced gravitational-wave detectors is to observe a stochastic gravitational-wave background. However, recent work demonstrates that correlated magnetic fields from Schumann resonances can produce correlated strain noise

The MBTA pipeline for detecting compact binary coalescences in the third LIGO–Virgo observing run [PDF]

open access: yesClassical and quantum gravity, 2020
We describe the multi-band template analysis (MBTA) search for gravitational waves signals from coalescences of compact objects in the LIGO–Virgo data, at the time of the third observing run (2019–2020), both for low-latency detections and for offline ...

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.
