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…

AT 2016blu: Accretion-Powered Outbursts in a Luminous Blue Variable and Compact Object Binary

Mojgan Aghakhanloo, Núria Torres-Albà, Nathan Smith +33

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…

JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl

Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22

We present new JWST mid-IR spectra and ground-based optical spectra of the lingering source at the position of SN 2010jl, which was a relatively nearby superluminous Type IIn super…

Radio and X-ray Observations of the Transitional Supernova 2019yvr: Insights into the Progenitor Mass-Loss History

Raphael Baer-way, Raphael Baer-Way, Poonam Chandra +8

The final life stages of the massive star progenitors of stripped-envelope supernovae (SESNe) are still an open question, especially when it comes to the timing and magnitude of th…

SN 2019vxm: A luminous and long-lived Type IIn supernova with early flash-ionisation features

Y. -Z. Cai, A. Pastorello, T. J. Moriya +38

We present the photometric and spectroscopic analysis of the luminous and long-lasting Type IIn supernova (SN) 2019vxm. The SN reaches a peak V-band absolute magnitude of MV = -20.…

First Results from the LSST Shadow Survey: The Restless Luminous Blue Variable AT2017des in the Virgo-Cluster Galaxy, NGC4532

Conor L. Ransome, Bhagya M. Subrayan, David J. Sand +66

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…
