SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae
Aysha Aamer, Matt Nicholl, Charlotte Angus +21
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\,202…
Final Moments III: Explosion Properties and Progenitor Constraints of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present analysis of the plateau and late-time phase properties of a sample of 39 Type II supernovae (SNe II) that show narrow, transient, high-ionization emission lines (i.e., "…
A Large-Scale Search for Photometrically Variable AGNs in Dwarf Galaxies Using the Young Supernova Experiment
Alexander Messick, Vivienne Baldassare, David O. Jones +12
We conduct an analysis of over 60,000 dwarf galaxies (7<=log(M_*/M_\odot)<=10) in search of photometric variability indicative of active galactic nuclei (AGNs). Using data from the…
An Updated Detection Pipeline for Precursor Emission in Type II Supernova 2020tlf
Wynn Jacobson-Galán, Sebastian Gonzalez, Shreyas Patel +34
We present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN…
