Search for eccentric NSBH and BNS mergers in the third observing run of Advanced LIGO and Virgo
Rahul Dhurkunde, Alexander H. Nitz
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…
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
M. Pillas, S. Antier, K. Ackley +78
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
Keisi Kacanja, Alexander H. Nitz
Most observed neutron stars have masses around 1.4 , consistent with current formation mechanisms. To date, no sub-solar mass neutron star has been observed. Observing a l…
Efficient Stochastic Template Bank using Inner Product Inequalities
Keisi Kacanja, Alexander H. Nitz, Shichao Wu +5
Gravitational wave searches are crucial for studying compact sources like neutron stars and black holes. Many sensitive modeled searches use matched filtering to compare gravitatio…
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…
Multi-messenger Astrophysics of Black Holes and Neutron Stars as Probed by Ground-based Gravitational Wave Detectors: From Present to Future
Alessandra Corsi, Lisa Barsotti, Emanuele Berti +12
The ground-based gravitational wave (GW) detectors LIGO and Virgo have enabled the birth of multi-messenger GW astronomy via the detection of GWs from merging stellar-mass black ho…
