Environmental noise in advanced LIGO detectors

open access: yes, 2022
The sensitivity of the Advanced LIGO detectors to gravitational waves can be affected by environmental disturbances external to the detectors themselves.

Photonic Metrology with Hierarchic Quantum Frequentist Bounds

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
This paper proposes photonic metrology with hierarchical quantum frequentist bounds. The present model tightens the Quantum Cramér‐Rao Bound using a hybrid classical‐quantum framework. The experiment validates the hierarchical frequentist bounds for single‐qubit phase estimation.

Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass

open access: yesJournal of High Energy Physics
We study supercooled first-order phase transitions above the QCD scale in a wide class of conformal Majoron-like U(1)′ models that explain the totality of active neutrino oscillation data and produce a detectable stochastic gravitational wave background (

THE PAST AND THE FUTURE OF DIRECT SEARCH OF GW FROM PULSARS IN THE ERA OF GW ANTENNAS

open access: yesActa Polytechnica, 2013
In this paper we will give an overview of the past and present status of Gravitational Wave (GW) research associated with pulsars, taking into account the target sensitivity achieved from interferometric laser GW antennas such as Tama, Geo, Ligo and ...

Discrepancy in tidal deformability of GW170817 between the Advanced LIGO twin detectors

open access: yesPhysical Review Research, 2019
We find that the Hanford and Livingston detectors of Advanced LIGO derive a distinct posterior probability distribution of binary tidal deformability Λ[over ̃] of the first binary-neutron-star merger GW170817.

The LIGO–LIGO cross correlation for the detection of relic scalar gravitational waves [PDF]

open access: yesNew Astronomy, 2012
In the earlier work arXiv:0706.3782 we studied the cross correlation between the Virgo interferometer and the MiniGRAIL resonant sphere for the detection of relic scalar gravitational waves (SGWs). We have shown that the overlap reduction function for the cross correlation between Virgo and the monopole mode of MiniGRAIL is very small, but a maximum ...

Polarization-Based Tests of Gravity with the Stochastic Gravitational-Wave Background

open access: yesPhysical Review X, 2017
The direct observation of gravitational waves with Advanced LIGO and Advanced Virgo offers novel opportunities to test general relativity in strong-field, highly dynamical regimes.

Studying how to improve the control system of seismic section of LIGO with the use of Capacitive Position Sensors (CPS)

open access: yes, 2019
I worked on this project during my stay at LIGO Hanford site: the seismic isolation control and reduction is a crucial matter of concern on site, because seismic motion affects the performance of the detector.

Noise line identification in LIGO S6 and Virgo VSR2

open access: yes, 2010
An important goal for LIGO (the Laser Interferometer Gravitational-Wave Observatory) and Virgo is to find periodic sources of gravitational waves. The LIGO and Virgo detectors are sensitive to a variety of noise of non-astrophysical origin, such as ...
