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…

Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq

Jeniveve Pearson, David J. Sand, Peter Lundqvist +85

We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…

GW190425: Pan-STARRS and ATLAS coverage of the skymap and limits on optical emission associated with FRB190425

S. J. Smartt, M. Nicholl, S. Srivastav +32

GW190425 is the second of only two binary neutron star (BNS) merger events to be significantly detected by the LIGO-Virgo- Kagra gravitational wave detectors. With a detection only…

Most Rotational Variables Dominated by a Single Bright Feature are CVn Stars

A. N. Heinze, Heather Flewelling, Mark E. Huber

We previously reported a rare class of variable star light curves isolated from a sample of 4.7 million candidate variables from the ATLAS survey. Dubbed `UCBH' light curves, they…

AT2022aedm and a new class of luminous, fast-cooling transients in elliptical galaxies

M. Nicholl, S. Srivastav, M. D. Fulton +49

We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).…

SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova

W. V. Jacobson-Galan, L. Dessart, R. Margutti +65

We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…
