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…
Constraints on Line-of-Sight Acceleration from O1-O4
Labani Roy, Alexander H. Nitz
A compact binary will experience a center-of-mass (CoM) acceleration in the vicinity of a massive third object. The line-of-sight (LOS) component of this acceleration is imprinted…
Las Cumbres Observatory Gravitational-Wave Follow-up in the Third and Fourth Observing Runs: Strengths and Weaknesses of a Rapid Response Galaxy Targeted Strategy
Ido Keinan, Iair Arcavi, D. Andrew Howell +34
We present a summary of gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telescopes during the third (O3) and fourth (O4) observing runs of the…
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…
Multiband parameter estimation with phase coherence and extrinsic marginalization: Extracting more information from low-SNR CBC signals in LISA data
Shichao Wu, Alexander H. Nitz, Ian Harry +4
This paper presents a novel coherent multiband analysis framework for characterizing stellar- and intermediate-mass binary black holes using LISA and next-generation ground-based d…
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…
Dynamic Normalization for Compact Binary Coalescence Searches in Non-Stationary Noise
S. Mozzon, L. K. Nuttall, A. Lundgren +3
The output of gravitational-wave interferometers, such as LIGO and Virgo, can be highly non-stationary. Broadband detector noise can affect the detector sensitivity on the order of…
