Hubble Space Telescope Deep Upper Limits Rule out a Surviving Massive Binary Companion to the Type Ic Supernova 2012fh

The Astrophysical Journal
Current explanations of the mass-loss mechanism for stripped-envelope supernovae (SNe) remain divided between single and binary progenitor systems. Here we obtain deep ultraviolet (UV) imaging with the Hubble Space Telescope (HST) of the Type Ic SN ...

Enabling Early Transient Discovery in LSST via Difference Imaging with DECam

The Astrophysical Journal Letters
We present SLIDE , a pipeline that enables transient discovery in data from the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST), using archival images from the Dark Energy Camera as templates for difference imaging.

SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae

The Astrophysical Journal
Superluminous supernovae (SLSNe) are some of the brightest explosions in the Universe, representing the extremes of stellar deaths. At the upper end of their distribution is SN 2023taz, in a dwarf galaxy at z = 0.407.

Analysis of a Type II Supernova Candidate at z = 3.19 from JWST’s COSMOS-Web Survey

The Astrophysical Journal
The launch of the James Webb Space Telescope (JWST) has enabled the discovery of a small but increasing sample of high-redshift core-collapse supernovae (CC SNe), which provide new tests of massive star evolution in the early Universe.

SN 2019cqc: A Hydrogen-rich Superluminous Supernova Showing Electron-scattering Signatures

The Astrophysical Journal
Hydrogen-rich superluminous supernovae without narrow emission lines (SLSNe-II) are rare transients whose powering mechanisms remain debated, particularly the role of circumstellar medium (CSM) interaction.
