The ePESSTO+ census of ZTF nuclear transients. I. What flares in galactic nuclei?
E. Concepción, T. Petrushevska, G. Leloudas +21
Transients in galactic nuclei arise from distinct processes, only some of which trace the supermassive black hole (SMBH). These include tidal disruption events (TDEs), changing-loo…
AT 2024qfm: a luminous fast blue optical transient at a redshift of z = 0.2267 identified by Lasair-ZTF
M. Fulton, S. J. Smartt, S. Srivastav +20
Luminous fast blue optical transients (LFBOTs) emit from x-ray to radio wavelengths, epitomised by the discovery of AT 2018cow in a host galaxy at 65 Mpc. In the following eight ye…
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…
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…
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…
