Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI
Szanna Zsíros, Tamás Szalai, Ilse De Looze +39
We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…
JWST NIRCam Observations of SN 1987A: Spitzer Comparison and Spectral Decomposition
Richard G. Arendt, Martha L. Boyer, Eli Dwek +24
JWST NIRCam observations at 1.5-4.5 m have provided broad and narrow band imaging of the evolving remnant of SN 1987A with unparalleled sensitivity and spatial resolution. Compa…
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…
Recovering lost light: discovery of supernova remnants with integral field spectroscopy
Héctor Martínez-Rodríguez, Lluís Galbany, Carles Badenes +8
We present results from a systematic search for broad ( 400 \kms) \ha\ emission in Integral Field Spectroscopy data cubes of 1200 nearby galaxies obtained with PMAS and…
Red Supergiant Candidates for Multimessenger Monitoring of the Next Galactic Supernova
Sarah Healy, Shunsaku Horiuchi, Marta Colomer Molla +5
We compile a catalog of 578 highly probable and 62 likely red supergiants (RSGs) of the Milky Way, which represents the largest list of Galactic RSG candidates designed for continu…
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 $\…
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…
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 3D Numerical Study of Anisotropies in Supernova Remnants
Soham Mandal, Paul C. Duffell, Abigail Polin +1
We develop a suite of 3D hydrodynamic models of supernova remnants (SNRs) expanding against the circumstellar medium (CSM). We study the Rayleigh-Taylor Instability (RTI) forming a…
Synthetic red supergiant explosion model grid for systematic characterization of Type II supernovae
Takashi J. Moriya, Bhagya M. Subrayan, Dan Milisavljevic +1
A new model grid containing 228,016 synthetic red supergiant explosions (Type II supernovae) is introduced. Time evolution of spectral energy distributions from 1 A to 50,000 A (10…
