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…
Peak 'Nebular' Emission and Early Flux Excesses in Ca-strong Supernovae
C. -G. Touchard-Paxton, K. Maguire, C. Frohmaier +27
Calcium-strong supernovae (Ca-strong SNe) are a class of thermonuclear transient characterised by rapid photometric evolution (rise times of <= 16 d) and nebular-phase spectra domi…
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…
ENGRAVE follow-up of a type IIb supernova spatially coincident with the sub-threshold gravitational wave trigger S250818k
K. Ackley, M. T. Botticella, A. Boye +54
The candidate gravitational wave (GW) event S250818k was one of only three non-retracted LIGO-Virgo-KAGRA public alerts issued during the fourth observing run of the network (O4) w…
Can tidal disruption event models reliably measure black hole masses?
C. R. Angus, A. J. Smith, D. Magill +15
Tidal disruption event (TDE) light curves are increasingly used to infer the masses of quiescent supermassive black holes (), offering a powerful probe of low-mass bla…
Pan-STARRS follow-up of the gravitational-wave event S250818k and the lightcurve of SN 2025ulz
J. H. Gillanders, M. E. Huber, M. Nicholl +30
Kilonovae are the scientifically rich, but observationally elusive, optical transient phenomena associated with compact binary mergers. Only a handful of events have been discovere…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?
P. G. Jonker, A. J. Levan, Xing Liu +41
Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…
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 2022jli: a type Ic supernova with periodic modulation of its light curve and an unusually long rise
Moore T., Smartt S. J., Nicholl M. +42
We present multi-wavelength photometry and spectroscopy of SN 2022jli, an unprecedented Type Ic supernova discovered in the galaxy NGC 157 at a distance of 23 Mpc. The mu…
Panning for gold, but finding helium: discovery of the ultra-stripped supernova SN2019wxt from gravitational-wave follow-up observations
I. Agudo, L. Amati, T. An +96
We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
The Complete Light-curve Sample of Spectroscopically Confirmed Type Ia Supernovae from Pan-STARRS1 and Cosmological Constraints from The Combined Pantheon Sample
D. M. Scolnic, D. O. Jones, A. Rest +37
We present optical light curves, redshifts, and classifications for 365 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Surv…

We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift discovered in the last months of the Pan-STARRS1 Medium De…
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…
Nebular spectra of pair-instability supernovae
A. Jerkstrand, S. J. Smartt, A. Heger
If very massive stars (M >~ 100 Msun) can form and avoid too strong mass loss during their evolution, they are predicted to explode as pair-instability supernovae (PISNe). One crit…
