The Pre-explosion Environments and The Progenitor of SN 2023ixf from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX)
Chenxu Liu, Xinlei Chen, Xinzhong Er +20
Supernova (SN) 2023ixf was discovered on May 19th, 2023. The host galaxy, M101, was observed by the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) collaboration over the pe…
Cosmological Distance Measurement of 12 Nearby Supernovae IIP with ROTSE-IIIB
Govinda Dhungana, Robert Kehoe, Ryan Staten +14
We present cosmological analysis of 12 nearby () Type IIP supernovae (SNe IIP) observed with the ROTSE-IIIb telescope. To achieve precise photometry, we present a new image…
Ground-based and JWST Observations of SN 2022pul: II. Evidence from Nebular Spectroscopy for a Violent Merger in a Peculiar Type-Ia Supernova
Lindsey A. Kwok, Matthew R. Siebert, Joel Johansson +78
We present an analysis of ground-based and JWST observations of SN~2022pul, a peculiar "03fg-like" (or "super-Chandrasekhar") Type Ia supernova (SN Ia), in the nebular phase at 338…
The LIGO HET Response (LIGHETR) Project to Discover and Spectroscopically Follow Optical Transients Associated with Neutron Star Mergers
M. J. Bustamante-Rosell, Greg Zeimann, J. Craig Wheeler +20
The LIGO HET Response (LIGHETR) project is an enterprise to follow up optical transients (OT) discovered as gravitational wave merger sources by the LIGO/Virgo collaboration (LVC).…
The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model
Gu Lim, Myungshin Im, Gregory S. H. Paek +19
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…
Limit on Supernova Emission in the Brightest Gamma-ray Burst, GRB 221009A
Manisha Shrestha, David J. Sand, Kate D. Alexander +30
We present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in th…
