Roaring to softly whispering: Persistent X-ray emission at the location of the Fast Blue Optical Transient AT2018cow 3.7 yrs after discovery and implications on accretion-powered scenarios
G. Migliori, R. Margutti, B. D. Metzger +11
We present the first deep X-ray observations of a luminous FBOT AT2018cow, at since discovery, together with the re-analysis of the observation at …
The Young Supernova Experiment: Survey Goals, Overview, and Operations
D. O. Jones, R. J. Foley, G. Narayan +68
Time domain science has undergone a revolution over the past decade, with tens of thousands of new supernovae (SNe) discovered each year. However, several observational domains, in…
Unprecedented X-ray Emission from the Fast Blue Optical Transient AT2022tsd
D. J. Matthews, R. Margutti, B. D. Metzger +8
We present the X-ray monitoring campaign of AT2022tsd in the time range d rest-frame since discovery. With an initial 0.3-10 keV X-ray luminosity of $L_x \a…
Radio Analysis of SN 2004C Reveals an Unusual CSM Density Profile as a Harbinger of Core Collapse
Lindsay DeMarchi, R. Margutti, J. Dittman +13
We present extensive multi-frequency VLA and VLBA observations of the radio-bright supernova (SN) IIb SN 2004C that span days post-explosion. We interpret the tempo…
An embedded X-ray source shines through the aspherical AT2018cow: revealing the inner workings of the most luminous fast-evolving optical transients
Raffaella Margutti, B. D. Metzger, R. Chornock +41
We present the first extensive radio to gamma-ray observations of a fast-rising blue optical transient (FBOT), AT2018cow, over its first ~100 days. AT2018cow rose over a few days t…
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…
