BOOM and Babamul: a real-time, multi-survey, optical alert broker system operating at scale
Theophile Jegou du Laz, Michael W. Coughlin, Peter Bachant +17
With the arrival of ever higher throughput wide-field surveys and a multitude of multi-messenger and multi-wavelength instruments to complement them, software capable of harnessing…
Large Language Model-driven Analysis of General Coordinates Network (GCN) Circulars
Vidushi Sharma, Ronit Agarwala, Judith L. Racusin +9
The General Coordinates Network (GCN) is NASA's time-domain and multimessenger alert system. GCN distributes two data products: automated "Notices" and human-generated "Circulars"…
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…
Identification and photometric classification of extragalactic transients in the Vera C. Rubin Observatory's Data Preview 1
James Freeburn, Igor Andreoni, Kaylee M. de Soto +55
The Vera C. Rubin Observatory will soon survey the southern sky, delivering a depth and sky coverage that is unprecedented in time domain astronomy. As part of commissioning, Data…
IIb or not IIb: A Catalog of ZTF Kilonova Imposters
Tyler Barna, Christoffer Fremling, Tomas Ahumada +12
Among the various classes of fast optical transients (FOTs), kilonovae (KNe), which can emerge as a result of neutron star mergers, are extremely challenging to observe because of…
Low-latency Forecasts of Kilonova Light Curves for Rubin and ZTF
Natalya Plestkova, Niharika Sravan, R. Weizmann Kiendrebeogo +11
Follow-up of gravitational-wave events by wide-field surveys is a crucial tool for the discovery of electromagnetic counterparts to gravitational wave sources, such as kilonovae. M…
