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…

The flash-ionised SN Ibn 2025kzr: H-free CSM formed during a precursor outburst 55 days prior to explosion

S. de Wet, G. Leloudas, D. A. H. Buckley +33

Type Ibn supernovae (SNe) are a class of interacting SNe characterised by narrow helium lines in their spectra. We present an extensive observational dataset of the Type Ibn SN 202…

ATLAS100 -- I. A volume-limited sample of supernovae and related transients within 100 Mpc

Shubham Srivastav, Stephen J. Smartt, Thomas Moore +29

We present ATLAS100 -- a sample of 1729 supernovae and other explosive optical transients within Mpc observed by the ATLAS survey over a span of 5.75 years from 2017 Sep…

The ATLAS Virtual Research Assistant

H. F. Stevance, K. W. Smith, S. J. Smartt +4

We present the Virtual Research Assistant (VRA) of the ATLAS sky survey which performs preliminary eyeballing on our clean transient data stream. The VRA uses Histogram Based Gradi…

Search for the Optical Counterpart of Einstein Probe Discovered Fast X-ray Transients from Lulin Observatory

Amar Aryan, Ting-Wan Chen, Sheng Yang +24

The launch of the Einstein Probe (EP) mission has revolutionized the detection and follow-up observations of fast X-ray transients (FXTs) by providing prompt and timely access to t…

Precursor Activity Preceding Interacting Supernovae I: Bridging the Gap with SN 2022mop

S. J. Brennan, S. Barmentloo, S. Schulze +41

Over the past two decades, an increasing number of transients have shown luminous activity at their explosion sites weeks to years before an interacting supernova (SN) is observed.…
