ZTF25abjmnps (AT2025ulz) and S250818k: A Candidate Superkilonova from a Sub-threshold Sub-Solar Gravitational Wave Trigger

Mansi M. Kasliwal, Tomas Ahumada, Robert Stein +61

On August 18, 2025, the LIGO-Virgo-KAGRA collaboration reported gravitational waves from a sub-threshold binary neutron star merger. If astrophysical, this event would have a surpr…

AT2025ulz and S250818k: Deep X-ray and radio limits on off-axis afterglow emission and prospects for future discovery

Brendan O'Connor, Roberto Ricci, Eleonora Troja +15

The first joint electromagentic (EM) and gravitational wave (GW) detection, known as GW170817, marked a critical juncture in our collective understanding of compact object mergers.…

AT2025ulz and S250818k: Investigating early time observations of a subsolar mass gravitational-wave binary neutron star merger candidate

Xander J. Hall, Malte Busmann, Hauke Koehn +32

Over the past LIGO--Virgo--KAGRA (LVK) observing runs, it has become increasingly clear that identifying the next electromagnetic counterparts to gravitational-wave (GW) neutron st…

Multi-messenger constraints on LIGO/Virgo/KAGRA gravitational wave binary black holes merging in AGN disks

Tomás Cabrera, Antonella Palmese, Maya Fishbach

While the LIGO/Virgo/KAGRA (LVK) gravitational wave (GW) detectors have detected over 300 binary black hole (BBH) mergers to date, the first confirmation of an electromagnetic (EM)…

Growing the Intermediate-mass Black Hole in Omega Centauri

Elena González Prieto, Carl L. Rodriguez, Tomás Cabrera

The recent detection of fast-moving stars in the core of Omega Centauri ( Cen), the most massive globular cluster (GC) in the Milky Way, has provided strong evidence for the pre…

LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: Zwicky Transient Facility observations

Tomás Ahumada, Shreya Anand, Mattia Bulla +49

We present the searches conducted with the Zwicky Transient Facility (ZTF) in response to S250206dm, a bona fide event with a false alarm rate of one in 25 years, detected by the I…

Kilonova constraints for the LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: GW-MMADS observations

Lei Hu, Tomás Cabrera, Antonella Palmese +35

Gravitational wave (GW) neutron star mergers with an associated electromagnetic counterpart constitute powerful probes of binary evolution, the production sites of heavy elements,…

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…
