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…
Discovery of the optical and radio counterpart to the fast X-ray transient EP240315a
J. H. Gillanders, L. Rhodes, S. Srivastav +36
Fast X-ray Transients (FXTs) are extragalactic bursts of soft X-rays first identified >10 years ago. Since then, nearly 40 events have been discovered, although almost all of these…
