Precision Ringdown Measurements of Binary Black Hole Remnants
Achal Kumar, Poulami Dutta Roy, Marek J. Szczepańczyk +1
The ringdown gravitational wave from a binary black hole (BBH) merger is a superposition of quasi-normal modes (QNMs) of the remnant black hole. In general relativity (GR), QNMs ar…
Joint Detection and Characterization of the Standing Accretion Shock Instability for Core-Collapse Supernovae with cWB XP
Vicente Sierra, Zidu Lin, Michelle Zanolin +3
The most sensitive to-date multimessenger detection of the standing accretion shock instability in real interferometric data is presented, which quantitatively identifies the prese…
Dedicated-frequency analysis of gravitational-wave bursts from core-collapse supernovae with minimal assumptions
Yi Shuen C. Lee, Marek J Szczepańczyk, Tanmaya Mishra +2
Gravitational-wave (GW) emissions from core-collapse supernovae (CCSNe) provide insights into the internal processes leading up to their explosions. Theory predicts that CCSN explo…
Assessing the Distance for Probing the Nuclear Equation of State with Supernova Gravitational Waves
Y. Sultan Abylkairov, Matthew C. Edwards, Artyom Ostrikov +6
Gravitational waves from core-collapse supernovae provide a unique probe of the equation of state (EOS) of high density matter. In this work, we focus on the bounce signal from num…
Targeted searches for gravitational waves from SN 2023ixf and SGR 1935+2154
Marek J. Szczepańczyk
The fourth observing run of Advanced LIGO, Advanced Virgo, and KAGRA has provided so far over 200 new gravitational-wave candidates, and it is still ongoing. A few results from thi…
Gravitational Waves Detected by a Burst Search in LIGO/Virgo's Third Observing Run
Tanmaya Mishra, Shubhagata Bhaumik, V. Gayathri +3
Burst searches identify gravitational-wave (GW) signals in the detector data without use of a specific signal model, unlike the matched-filter searches that correlate data with sim…
Gravitational Wave Detector Sensitivity to Eccentric Black Hole Mergers
Shubhagata Bhaumik, V. Gayathri, Imre Bartos +8
Orbital eccentricity in compact binary mergers carries crucial information about the binary's formation and environment. There are emerging signs that some of the mergers detected…
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the Third Observing Run of Advanced LIGO and Advanced Virgo
Marek J. Szczepańczyk, Yanyan Zheng, Javier M. Antelis +35
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed optically within 30 Mpc during the third observing run of A…
Characterizing the gravitational wave temporal evolution of the gmode fundamental resonant frequency for a core collapse supernova: A neural network approach
Alejandro Casallas Lagos, Javier M. Antelis, Claudia Moreno +3
We present a methodology based on the implementation of a fully connected neural network to estimate the gravitational wave (GW) temporal evolution of the gmode fundamental resonan…
Using supervised learning algorithms as a follow-up method in the search of gravitational waves from core-collapse supernovae
Javier M. Antelis, Marco Cavaglia, Travis Hansen +5
We present a follow-up method based on supervised machine learning (ML) to improve the performance in the search of gravitational wave (GW) burts from core-collapse supernovae (CCS…
Point Absorber Limits to Future Gravitational-Wave Detectors
W. Jia, H. Yamamoto, K. Kuns +198
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors…
Minimally-modeled search of higher multipole gravitational-wave radiation in compact binary coalescence
G. Vedovato, E. Milotti, G. A. Prodi +13
As the Advanced LIGO and Advanced Virgo interferometers, soon to be joined by the KAGRA interferometer, increase their sensitivity, they detect an ever-larger number of gravitation…
Approaching the motional ground state of a 10 kg object
Chris Whittle, Evan D. Hall, Sheila Dwyer +197
The motion of a mechanical object -- even a human-sized object -- should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: th…
All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369
Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…
Reducing Scattered Light in LIGO's Third Observing Run
S Soni, C Austin, A Effler +195
Noise due to scattered light has been a frequent disturbance in the Advanced LIGO gravitational wave detectors, hindering the detection of gravitational waves. The non stationary s…
Quantum correlations between the light and kilogram-mass mirrors of LIGO
Haocun Yu, L. McCuller, M. Tse +196
Measurement of minuscule forces and displacements with ever greater precision encounters a limit imposed by a pillar of quantum mechanics: the Heisenberg uncertainty principle. A l…
