We present ATLAS100 – a sample of 1729 supernovae and other explosive optical transients within 100 Mpc observed by the ATLAS survey over a span of 5.75 years from 2017 to 2023.

Identifying Transient Hosts in LSST’s Deep Drilling Fields with Galaxy Catalogues
Josh G. Weston, David R. Young, Stephen J. Smartt, and 3 more authors
The upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will enable astronomers to discover rare and distant astrophysical transients. Host-galaxy association is crucial for selecting the most scientifically interesting transients for follow-up.

Training a convolutional neural network for real–bogus classification in the ATLAS survey
J G Weston, K W Smith, S J Smartt, and 2 more authors
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 subsequent efforts to improve performance since initial development.

Discovery of the Optical and Radio Counterpart to the Fast X-Ray Transient EP 240315a
J. H. Gillanders, L. Rhodes, S. Srivastav, and 7 more authors
Fast X-ray Transients (FXTs) are extragalactic bursts of soft X-rays. Here we report the first discovery of both an optical and radio counterpart to a distant FXT, EP 240315a, at redshift z = 4.859.

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event
M. Nicholl, D. R. Pasham, A. Mummery, and 18 more authors
We report the detection of nine X-ray quasi-periodic eruptions from AT2019qiz, a nearby and extensively studied optically-selected tidal disruption event.

SN 2022jli: A Type Ic Supernova with Periodic Modulation of Its Light Curve and an Unusually Long Rise
T. Moore, S. J. Smartt, M. Nicholl, and 4 more authors
We present multiwavelength photometry and spectroscopy of SN 2022jli, an unprecedented Type Ic supernova with periodic undulations of 12.5 days superimposed on the 200-day decline – the first repeated periodic oscillations detected in a supernova light curve.
