Nearby Supernova Science in the Era of High Cadence, Deep Time Domain Surveys

David J. Sand, Bhagya Subrayan, Conor L. Ransome +41

We discuss science opportunities for nearby supernovae (SNe) in the era of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST), emphasizing the youngest phases o…

Tomography analysis of the intermediate-luminosity Type Iax SN 2024pxl

Barnabás Barna, Mridweeka Singh, Lindsey A. Kwok +90

We present an abundance tomography analysis of SN 2024pxl, an intermediate luminosity Type Iax supernova ( mag), with the most-detailed follow-up in the Type…

First Pre-peak Ultraviolet Spectrum of a Tidal Disruption Event: A Fast Outflow Revealed Prior to Maximum Light in TDE2025aarm

Erica Hammerstein, Ryan Chornock, Jean Somalwar +32

The tidal disruption and eventual accretion of a star by a massive black hole can lead to the launching of outflows and winds that encode important information about the tidal disr…

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…

No Evidence for Nearby Circumstellar Material in the Type Ia Supernova 2025rbs

Aravind P. Ravi, Griffin Hosseinzadeh, Stefano Valenti +28

We present a high-resolution spectral time series of the Type Ia supernova (SN) 2025rbs discovered in the nearby galaxy NGC 7331. The Automated Planet Finder (APF) at Lick Observat…
