Ready for O4 II: GRANDMA Observations of Swift GRBs during eight-weeks of Spring 2022
I. Tosta e Melo, J. -G. Ducoin, Z. Vidadi +106
We present a campaign designed to train the GRANDMA network and its infrastructure to follow up on transient alerts and detect their early afterglows. In preparation for O4 II camp…
Simulation-based inference for stochastic gravitational wave background data analysis
James Alvey, Uddipta Bhardwaj, Valerie Domcke +2
The next generation of space- and ground-based facilities promise to reveal an entirely new picture of the gravitational wave sky: thousands of galactic and extragalactic binary si…
A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run
C. Fletcher, J. Wood, R. Hamburg +1696
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate even…
What to do when things get crowded? Scalable joint analysis of overlapping gravitational wave signals
James Alvey, Uddipta Bhardwaj, Samaya Nissanke +1
The gravitational wave sky is starting to become very crowded, with the fourth science run (O4) at LIGO expected to detect compact object coalescence signals. Da…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about funda…
Peregrine: Sequential simulation-based inference for gravitational wave signals
Uddipta Bhardwaj, James Alvey, Benjamin Kurt Miller +2
The current and upcoming generations of gravitational wave experiments represent an exciting step forward in terms of detector sensitivity and performance. For example, key upgrade…
Open data from the third observing run of LIGO, Virgo, KAGRA and GEO
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1741
The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data…
