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…
Prospects of electromagnetic follow-up of neutron star-black hole mergers in the LIGO-India era
Yogita Kumari, Kanchan Soni, Sanjit Mitra
Neutron star-black hole (NSBH) mergers are promising multimessenger sources, but only a subset is expected to produce detectable electromagnetic (EM) counterparts, depending on 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…
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 statistic for the identification of strongly lensed gravitational waves from compact binary coalescences
Sudhir Gholap, Kanchan Soni, Shasvath J. Kapadia +1
Gravitational waves (GWs) emanated by stellar mass compact binary coalescences (CBCs), and lensed by galaxy- or cluster-scale lenses, will produce two or more copies of the GW sign…
Hierarchical searches for subsolar-mass binaries and the third-generation gravitational wave detector era
Kanchan Soni, Alexander H. Nitz
The detection of gravitational waves (GWs) from coalescing compact binaries has become routine with ground-based detectors like LIGO and Virgo. However, beyond standard sources suc…
Assessing the potential of LIGO-India in resolving the Hubble tension
Kanchan Soni, Aditya Vijaykumar, Sanjit Mitra
Conclusive determination of the Hubble constant () is a major challenge in current astronomy due to the observed discrepancies between early and late universe measurements. Jo…
Detectability of eccentric binary black holes with PyCBC and cWB pipelines during the third observing run of LIGO-Virgo-KAGRA
Bhooshan Gadre, Kanchan Soni, Shubhanshu Tiwari +3
Detecting binary black hole (BBH) mergers with quantifiable orbital eccentricity would confirm the existence of a dynamical formation channel for these binaries. The current state-…
