Search For a Counterpart to the Subsolar Mass Gravitational Wave Candidate S251112cm
Nicholas Vieira, Noah Franz, Bhagya Subrayan +49
The recent candidate gravitational-wave (GW) alert from a compact object merger involving at least one subsolar mass (SSM) object has prompted questions about their origins. S25111…
Searching for Binary Black Hole Merger Emission in AGN Disks: Optical and Spectroscopic Follow-up of S240413p
P. Darc, C. R. Bom, A. Santos +7
The conditions under which binary black hole (BBH) mergers embedded in active galactic nucleus (AGN) disks produce detectable optical counterparts remain poorly constrained observa…
Improved constraint on the Hubble constant from dark sirens with LIGO/Virgo/KAGRA O4a
V. Alfradique, C. R. Bom, G. Teixeira +1
A new measurement of the Hubble constant is presented using the statistical dark siren method applied to a sample of seven well-localized gravitational-wave (GW) events from…
Long-Term Optical Follow Up of S231206cc: Multi-Model Constraints on BBH Merger Emission in AGN Disks
P. Darc, C. R. Bom, C. D. Kilpatrick +9
The majority of gravitational wave events detected by the LIGO, Virgo, and KAGRA Collaboration originate from binary black hole (BBH) mergers, for which no confirmed electromagneti…
Transient Classifiers for Fink: Benchmarks for LSST
B. M. O. Fraga, C. R. Bom, A. Santos +6
The upcoming Legacy Survey of Space and Time (LSST) is expected to detect a few million transients per night, which will generate a live alert stream during the entire ten years of…
A dark standard siren measurement of the Hubble constant following LIGO/Virgo/KAGRA O4a and previous runs
C. R. Bom, V. Alfradique, A. Palmese +4
We present a new constraint on the Hubble constant () from the standard dark siren method using a sample of well-covered gravitational waves (GW) alerts reported during th…
