Search for Eccentric Neutron Star-Black Hole Binaries in Advanced LIGO's Fourth Observing Run using Effective-One-Body Waveforms
Aleyna Akyüz, Keisi Kacanja, Rahul Dhurkunde +1
The observation of orbital eccentricity in compact binary coalescences would provide a direct signature of dynamical formation environments. Previous matched-filter searches for ec…
Search for Sub-Solar Mass Binaries in the First and Second Part of LIGO's Fourth Observing Run O4a-O4b
Keisi Kacanja, Kanchan Soni, Alexander H. Nitz
The observation of sub-solar mass neutron stars and black holes would signify a new class of astrophysical objects since these systems are not expected to form via standard stellar…
Search for Sub-Solar Mass Binaries in the First Part of LIGO's Fourth Observing Run
Keisi Kacanja, Kanchan Soni, Aleyna Akyüz +1
We report the first results of a sub-solar mass compact binary search using the data from the first part of the fourth observing run (O4a) of the Advanced LIGO detectors. Sub-solar…
Beyond FINDCHIRP: Breaking the memory wall and optimal FFTs for Gravitational-Wave Matched-Filter Searches with Ratio-Filter Dechirping
Alexander H. Nitz, Keisi Kacanja, Kanchan Soni
A primary bottleneck in modern FFT-based matched-filter searches for gravitational waves from compact binary coalescences is not raw processor throughput, but available memory band…
Potential science with GW250114 -- the loudest binary black hole merger detected to date
Aleyna Akyüz, Alex Correia, Jada Garofalo +7
On January 14, 2025 the LIGO interferometers detected a gravitational wave from the merger of two black holes, GW250114. Using publicly available information, we estimate that the…
Eccentricity signatures in LIGO-Virgo-KAGRA's BNS and NSBH binaries
Keisi Kacanja, Kanchan Soni, Alexander Harvey Nitz
Measurement of eccentricity in low-mass binary systems through gravitational waves is crucial to distinguish between various formation channels. Detecting eccentricity in these sys…
Mining the Alerts: A Preliminary Catalog of Compact Binaries from the Fourth Observing Run
Aleyna Akyüz, Alex Correia, Jada Garofalo +7
We present a preliminary catalog of compact binary merger candidates from the ongoing fourth observing run (O4) of Advanced LIGO, Virgo, and KAGRA, based on an analysis of public a…
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…
Measuring Neutron Star Radius with second and third generation Gravitational Wave Detector Networks
Ananya Bandopadhyay, Keisi Kacanja, Rahul Somasundaram +2
The next generation of ground-based interferometric gravitational wave detectors will observe mergers of black holes and neutron stars throughout cosmic time. A large number of the…
Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer
Ish Gupta, Chaitanya Afle, K. G. Arun +44
Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
Cosmic Explorer: A Submission to the NSF MPSAC ngGW Subcommittee
Matthew Evans, Alessandra Corsi, Chaitanya Afle +73
Gravitational-wave astronomy has revolutionized humanity's view of the universe, a revolution driven by observations that no other field can make. This white paper describes an obs…
