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…
Identifying Transient Hosts in LSST's Deep Drilling Fields with Galaxy Catalogues
Josh G. Weston, David R. Young, Stephen J. Smartt +3
The upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will enable astronomers to discover rare and distant astrophysical transients. Host-galaxy association…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
SN 2020pvb: a Type IIn-P supernova with a precursor outburst
Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37
We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…
A year-long plateau in the late-time near-infrared light curves of Type Ia supernovae
Or Graur, Kate Maguire, Russell Ryan +6
The light curves of Type Ia supernovae are routinely used to constrain cosmology models. Driven by radioactive decay of 56Ni, the light curves steadily decline over time, but >150…
Evidence for rapid disk formation and reprocessing in the X-ray bright tidal disruption event AT 2018fyk
T. Wevers, D. R. Pasham, S. van Velzen +15
We present optical spectroscopic and Swift UVOT/XRT observations of the X-ray and UV/optical bright tidal disruption event (TDE) AT 2018fyk/ASASSN-18ul discovered by ASAS-SN. The S…
Complexity in the light curves and spectra of slow-evolving superluminous supernovae
C. Inserra, M. Nicholl, T. -W. Chen +15
A small group of the newly discovered superluminous supernovae show broad and slowly evolving light curves. Here we present extensive observational data for the slow-evolving super…
The evolution of superluminous supernova LSQ14mo and its interacting host galaxy system
T. -W. Chen, M. Nicholl, S. J. Smartt +26
We present and analyse an extensive dataset of the superluminous supernova (SLSN) LSQ14mo (z = 0.256), consisting of a multi-colour lightcurve from -30 d to +70 d in the rest-frame…
Pan-STARRS and PESSTO search for an optical counterpart to the LIGO gravitational wave source GW150914
S. J. Smartt, K. C. Chambers, K. W. Smith +48
We searched for an optical counterpart to the first gravitational wave source discovered by LIGO (GW150914), using a combination of the Pan-STARRS1 wide-field telescope and the PES…
Seeing double: the frequency and detectability of double-peaked superluminous supernova light curves
M. Nicholl, S. J. Smartt
The discovery of double-peaked light curves in some superluminous supernovae offers an important new clue to their origins. We examine the published photometry of all Type Ic SLSNe…
On the diversity of super-luminous supernovae: ejected mass as the dominant factor
M. Nicholl, S. J. Smartt, A. Jerkstrand +37
We assemble a sample of 24 hydrogen-poor super-luminous supernovae (SLSNe). Parameterizing the light curve shape through rise and decline timescales shows that the two are highly c…
