Inferring additional physics through unmodelled signal reconstructions
Rimo Das, V. Gayathri, Divyajyoti +4
Parameter estimation of gravitational wave data is often computationally expensive, requiring simplifying assumptions such as circularisation of binary orbits. Although, if include…
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…
Search for gravitational waves emitted from SN 2023ixf
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
We present the results of a search for gravitational-wave transients associated with core-collapse supernova SN 2023ixf, which was observed in the galaxy Messier 101 via optical em…
A search using GEO600 for gravitational waves coincident with fast radio bursts from SGR 1935+2154
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by CHIME/FRB and STARE2 in 2020 April, after t…
Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run
Gayathri Raman, Samuele Ronchini, James Delaunay +1819
We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…
