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 …

We present a detailed study on SN2019szu, a Type I superluminous supernova at z= 0.213
that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF …

We present the first deep X-ray observations of luminous fast blue optical transient (LFBOT)
AT 2018cow at∼ 3.7 yr since discovery, together with the reanalysis of the observation at …

The population of optical transients evolving within a time-scale of a few hours or a day (so-
called fast optical transients, FOTs) has recently been debated extensively. In particular, our …

We present multiwavelength photometry and spectroscopy of SN 2022jli, an unprecedented
Type Ic supernova discovered in the galaxy NGC 157 at a distance of≈ 23 Mpc. The …

Close encounters between stellar-mass black holes (BHs) and stars occur frequently in
dense star clusters and in the disks of active galactic nuclei. Recent studies have shown that …

ABSTRACT SN 2023tsz is a Type Ibn supernova (SN Ibn), an uncommon subtype of
stripped-envelope core-collapse supernovae (SNe), discovered in an extremely low-mass …

We present a convolutional neural network (CNN) for use in the real–bogus classification of
transient detections made by the Asteroid Terrestrial-impact Last Alert System (ATLAS) and …

We present multiwavelength data of SN 2020acct, a double-peaked stripped-envelope
supernova (SN) in NGC 2981 at∼ 150 Mpc. The two peaks are temporally distinct, with …

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