We present UV and/or optical observations and models of SN 2023ixf, a type II supernova
(SN) located in Messier 101 at 6.9 Mpc. Early time (flash) spectroscopy of SN 2023ixf …

We present early-phase panchromatic photometric and spectroscopic coverage spanning
the far-ultraviolet to near-infrared regime of the nearest hydrogen-rich core-collapse …

We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at
14.5 Mpc. This wealth of multiwavelength data allows us to compare different metrics …

We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-
resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred …

We present high-cadence photometric and spectroscopic observations of SN 2023axu, a
classical Type II supernova with an absolute V-band peak magnitude of–17.2±0.1 mag. SN …

We examine the binding energies of massive stripped-envelope core collapse supernova
(SECCSN) progenitors with the stellar evolution code mesa, and find that the jittering jets …

We present the hydrodynamic model of Type IIP SN 2020jfo with the unusually short (∼ 60
d) light-curve plateau. The model suggests the explosion of≈ 8 M⊙ red supergiant that …

We present photometric, spectroscopic, and polarimetric observations of the intermediate-
luminosity Type IIP supernova (SN) 2021gmj from 1 to 386 d after the explosion. The peak …

Context. Type II supernovae offer a direct way of estimating distances via the expanding
photosphere method, which is independent of the cosmic distance ladder. A Gaussian …

We present detailed multiband photometric and spectroscopic observations and analysis of
a rare core-collapse supernova, SN 2021wvw, that includes photometric evolution up to 250 …
