The Extremely Metal-Poor SN 2023ufx: A Local Analog to High-Redshift Type II Supernovae
Michael A. Tucker, Jason Hinkle, Charlotte R. Angus +26
We present extensive observations of the Type II supernova (SN II) 2023ufx which is likely the most metal-poor SN II observed to-date. It exploded in the outskirts of a low-metalli…
Probing the Soft X-ray Properties and Multi-Wavelength Variability of SN2023ixf and its Progenitor
Sonja Panjkov, Katie Auchettl, Benjamin J. Shappee +3
We present a detailed analysis of nearly two decades of optical/UV and X-ray data to study the multi-wavelength pre-explosion properties and post-explosion X-ray properties of near…
Hawai'i Supernova Flows: A Peculiar Velocity Survey Using Over a Thousand Supernovae in the Near-Infrared
Aaron Do, Benjamin J. Shappee, John L. Tonry +15
We introduce the Hawai'i Supernova Flows project and present summary statistics of the first 1,217 astronomical transients observed, 668 of which are spectroscopically classified T…
Characterizing the Rapid Hydrogen Disappearance in SN2022crv: Evidence of a Continuum between Type Ib and IIb Supernova Properties
Yize Dong, Stefano Valenti, Chris Ashall +52
We present optical and near-infrared observations of SN~2022crv, a stripped envelope supernova in NGC~3054, discovered within 12 hrs of explosion by the Distance Less Than 40 Mpc S…
Optical and near-infrared photometry of 94 type II supernovae from the Carnegie Supernova Project
J. P. Anderson, C. Contreras, M. D. Stritzinger +43
Type II supernovae (SNeII) mark the endpoint in the lives of hydrogen-rich massive stars. Their large explosion energies and luminosities allow us to measure distances, metalliciti…
The DEHVILS in the Details: Type Ia Supernova Hubble Residual Comparisons and Mass Step Analysis in the Near-Infrared
Erik R. Peterson, Daniel Scolnic, David O. Jones +11
Measurements of Type Ia Supernovae (SNe Ia) in the near-infrared (NIR) have been used both as an alternate path to cosmology compared to optical measurements and as a method of con…
