Enabling Early Transient Discovery in LSST via Difference Imaging with DECam
The Astrophysical Journal LettersWe 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 JournalSuperluminous 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.

Hydrogen-Poor Core-Collapse Supernovae
, 2016 Hydrogen-poor core-collapse supernovae (SNe) signal the explosive death of stars more massive than the progenitors of hydrogen-rich core-collapse supernovae, i.e., approximately in the range 15-50 M☉ in main sequence. Since hydrogen-poor core-collapse supernovae include those that accompany gamma-ray bursts (GRBs), which were all rigorously identified ...

Supernova Siblings and Spectroscopic Host Galaxy Properties
The Astrophysical JournalOver the past century, supernova (SN) searches have detected multiple supernovae (SNe) in hundreds of individual galaxies. So-called SN siblings discovered in the same galaxy present an opportunity to constrain the dependence of the properties of SNe on ...
