Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed

Neutron star-black hole (NSBH) mergers, detectable via their gravitational-wave (GW) emission, are expected to produce kilonovae (KNe). Four NSBH candidates have been identified an…
A Search for Low-Mass Neutron Stars in the Third Observing Run of Advanced LIGO and Virgo

The possible formation histories of neutron star binaries remain unresolved by current gravitational-wave catalogs. The detection of an eccentric binary system could be vital in co…
Targeted Search for Gravitational Waves from Highly Spinning Light Compact Binaries
Yi-Fan Wang, Alexander H. Nitz
Searches for gravitational waves from compact-binary mergers, which to date have reported observations, have previously ignored binaries whose components are both consist…
Space-based Gravitational Wave Observatories Will Be Able to Use Eccentricity to Unveil Stellar-mass Binary Black Hole Formation
Han Wang, Ian Harry, Alexander Nitz +1
The measurement of eccentricity would provide strong constraints on the formation channel of stellar-mass binary black holes. However, current ground-based gravitational wave detec…
