Search for subsolar-mass black hole binaries in the second part of Advanced LIGO's and Advanced Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1702
We describe a search for gravitational waves from compact binaries with at least one component with mass 0.2 -- and mass ratio in Advanced LIGO…
A complete measurement of a black-hole recoil through higher-order gravitational-wave modes
Juan Calderón Bustillo, Samson H. W. Leong, Koustav Chandra
General relativity predicts that gravitational waves (GWs) carry linear momentum. Consequently, the remnant black hole of a black-hole merger can inherit a recoil velocity or ``kic…
Search for gravitational-wave transients associated with magnetar bursts in Advanced LIGO and Advanced Virgo data from the third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1667
Gravitational waves are expected to be produced from neutron star oscillations associated with magnetar giant flares and short bursts. We present the results of a search for short-…
Model-based cross-correlation search for gravitational waves from the low-mass X-ray binary Scorpius X-1 in LIGO O3 data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…
Fishing massive black hole binaries with THAMES
Kritti Sharma, Koustav Chandra, Archana Pai
Hierarchical mergers in a dense environment are one of the primary formation channels of intermediate-mass black hole (IMBH) binary system. We expect that the resulting massive bin…
First gravitational-wave search for intermediate-mass black hole mergers with higher order harmonics
Koustav Chandra, Juan Calderón Bustillo, Archana Pai +1
Current matched-filter searches for gravitational waves from binary black-hole mergers compare the calibrated detector data to waveform templates that omit the higher-order mode co…
Searching for vector boson-star mergers within LIGO-Virgo intermediate-mass black-hole merger candidates
Juan Calderon Bustillo, Nicolas Sanchis-Gual, Samson H. W. Leong +7
We present the first systematic search for exotic compact mergers in Advanced LIGO and Virgo events. We compare the short gravitational-wave signals GW190521, GW190426190642, G…
Gravitational-wave parameter inference with the Newman-Penrose scalar
Juan Calderon Bustillo, Isaac C. F. Wong, Nicolas Sanchis-Gual +7
Detection and parameter inference of gravitational-wave signals \ncor{from compact mergers} rely on the comparison of the incoming detector strain data to waveform templates…
Search for continuous gravitational wave emission from the Milky Way center in O3 LIGO--Virgo data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1667
We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling e…
Search for Gravitational Waves Associated with Fast Radio Bursts Detected by CHIME/FRB During the LIGO--Virgo Observing Run O3a
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1654
We search for gravitational-wave transients associated with fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/…
First joint observation by the underground gravitational-wave detector, KAGRA, with GEO600
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669
We report the results of the first joint observation of the KAGRA detector with GEO600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser inter…
Search for gravitational waves from Scorpius X-1 with a hidden Markov model in O3 LIGO data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669
Results are presented for a semi-coherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using a hidden Markov model (HMM) to allow for spin…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO and Advanced Virgo O3 data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1667
We present results of an all-sky search for continuous gravitational waves which can be produced by spinning neutron stars with an asymmetry around their rotation axis, using data…
