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…

Results from the Pan-STARRS Search for Kilonovae: Contamination by Massive Stellar Outbursts

M. D. Fulton, S. J. Smartt, M. E. Huber +11

We present results from the Pan-STARRS optical search for kilonovae without the aid of gravitational wave and gamma-ray burst triggers. The search was conducted from 26 October 201…

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.…

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event

M. Nicholl, D. R. Pasham, A. Mummery +61

Quasi-periodic Eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems i…

Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models

C. R. Angus, S. E. Woosley, R. J. Foley +35

We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…

Identification of the optical counterpart of the fast X-ray transient EP240414a

S. Srivastav, T. -W. Chen, J. H. Gillanders +26

Fast X-ray transients (FXTs) are extragalactic bursts of X-rays first identified in archival X-ray data, and now routinely discovered by the Einstein Probe in real time, which is c…

A systematically-selected sample of luminous, long-duration, ambiguous nuclear transients

P. Wiseman, R. D. Williams, I. Arcavi +12

We present a search for luminous, long-duration ambiguous nuclear transients (ANTs) similar to the unprecedented discovery of the extreme, ambiguous event AT2021lwx with a \,…

SN 2023zaw: the low-energy explosion of an ultra-stripped star

T. Moore, J. H. Gillanders, M. Nicholl +26

Most stripped-envelope supernova progenitors are thought to be formed through binary interaction, losing hydrogen and/or helium from their outer layers. Ultra-stripped supernovae a…

XMM-Newton-discovered Fast X-ray Transients: Host galaxies and limits on contemporaneous detections of optical counterparts

D. Eappachen, P. G. Jonker, J. Quirola-Vásquez +18

Extragalactic fast X-ray transients (FXTs) are a class of soft (0.3-10 keV) X-ray transients lasting a few hundred seconds to several hours. Several progenitor mechanisms have been…
