A Significant Dust Reservoir Uncovered with JWST in the Type Ic SN 1983V More Than 40 Years Post-Explosion
Sophia S. Kressy, Thomas Moore, Ori D. Fox +26
Searching for late-time emission from supernovae (SNe) is an active field. Infrared (IR) wavelengths are sensitive to thermal emission from dust, which can be used to probe SN cont…

We present the first X-ray detection of the supernova (SN) impostor AT 2016blu in NGC 4559. AT 2016blu exhibited 27 detected quasiperiodic (~113 day) outbursts between 2012 and Jun…
Same explosion, many faces: numerical modeling reveals viewing angle as a driver of diversity for core-collapse SNe in binary systems
Soham Mandal, Raphael Baer-way, Shazrene Mohamed +3
Observable properties of core-collapse supernovae (CCSNe) depend sensitively on the circumstellar material (CSM) formed by pre-explosion mass loss from the progenitor star. Since a…

The Legacy Survey of Space and Time (LSST) will start in late-summer 2026, revolutionizing transient astronomy. Here, we present the Dark Energy Camera (DECam) Shadow Survey, which…
Identification of a Radio Counterpart to SN 2025ulz in the S250818k Localization Area
Tanner O'Dwyer, Alessandra Corsi, Deepika Yadav +12
On 2025 August 18, the LIGO-Virgo-KAGRA collaboration reported S250818k, a sub-threshold gravitational-wave (GW) candidate consistent with a binary neutron star (NS) merger potenti…
Fading Echoes of Interaction: Probing Centuries of Preexplosion Mass-Loss in Four Type IIn Supernovae
Elizabeth Hillenkamp, Raphael Baer-Way, Poonam Chandra +6
Supernovae characterized by enduring narrow optical hydrogen emission lines (SNe IIn) are believed to result primarily from the core-collapse of massive stars undergoing sustained…
A multiwavelength view of the nearby Calcium-Strong Transient SN 2025coe in the X-Ray, Near-Infrared, and Radio Wavebands
Sahana Kumar, Raphael Baer-Way, Aravind P. Ravi +18
Calcium-strong transients (CaSTs) are a subclass of faint and rapidly evolving supernovae (SNe) that exhibit strong calcium features and notably weak oxygen features. The small but…
The Double-Peaked Calcium-Strong SN 2025coe: Progenitor Constraints from Early Interaction and Ejecta Asymmetries
Aravind P. Ravi, Sahana Kumar, Raphael Baer-Way +47
Supernova (SN) 2025coe at a distance of 25 Mpc is the second-closest calcium-strong (CaST) transient. It was discovered at a large projected offset of 34 kpc from its p…
