AT2025agpz in Rubin commissioning data: distinguishing a luminous interacting supernova from nuclear transients in compact galaxies
C. R. Angus, M. Quilt, H. F. Stevance +37
The Vera C. Rubin Observatory's Legacy Survey of Space and Time will discover unprecedented numbers of rare, long-lived optical transients, many of which will be too faint or too n…
Decadal pre-explosion activity and circumstellar interaction in a supernova
Ting-Wan Chen, Amar Aryan, Sheng Yang +52
When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
The Enigmatic Type Icn Supernova 2024abvb Located ~22 kpc from Its Host Galaxy
J. Shi, K. Auchettl, W. B. Hoogendam +29
We report multiwavelength observations of the highly offset (~22.4 kpc) SN 2024abvb, the sixth Type Icn supernova to date. With a peak magnitude of Mr = -19.55 +/- 0.11 mag, it is…
The Dark Energy Bedrock All-Sky Supernova Program: Motivation, Design, Implementation, and Preliminary Data Release
Nora F. Sherman, Maria Acevedo, Dillon Brout +20
Precise measurements of Type Ia supernovae (SNe Ia) at low redshifts () serve as one of the most viable keys to unlocking our understanding of cosmic expansion, isotropy, and gr…
A Trifecta of Modelling Tools: A Bayesian Binary Black Hole Model Selection combining Population Synthesis and Galaxy Formation Models
Liana Rauf, Cullan Howlett, Simon Stevenson +2
Gravitational waves (GWs) have revealed surprising properties of binary black hole (BBH) populations, but there is still mystery surrounding how these compact objects evolve. We ap…
