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…
Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc
A. Gkini, C. Fransson, R. Lunnan +47
We present photometric and spectroscopic observations of SN 2020xga and SN 2022xgc, two hydrogen-poor superluminous supernovae (SLSNe-I) at and , respectiv…
Unveiling the True Nature of Plasma Dynamics from the Reference Frame of a Super-penumbral Fibril
W. Bate, D. B. Jess, S. D. T. Grant +11
The magnetic geometry of the solar atmosphere, combined with projection effects, makes it difficult to accurately map the propagation of ubiquitous waves in fibrillar structures. T…
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…
