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 d…
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).…
Luminous Radio Emission from the Superluminous Supernova 2017ens at 3.3 years after explosion
Raffaella Margutti, J. S. Bright, D. J. Matthews +17
We present the results from a multi-year radio campaign of the superluminous supernova (SLSN) 2017ens, which yielded the earliest radio detection of a SLSN to date at the age of $\…
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 \ap…
A radio-emitting outflow produced by the tidal disruption event AT2020vwl
A. J. Goodwin, K. D. Alexander, J. C. A. Miller-Jones +12
A tidal disruption event (TDE) occurs when a star is destroyed by a supermassive black hole. Broadband radio spectral observations of TDEs trace the emission from any outflows or j…
