Final Moments. II. Observational Properties and Physical Modeling of Circumstellar-material-interacting Type II Supernovae

The Astrophysical Journal
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early time ( δ t < 2 days) spectra show transient, narrow emission lines from shock ionization of confined ( r < 10 ^15 cm) circumstellar material

A 3D Simulation of a Type II-P Supernova: From Core Bounce to beyond Shock Breakout

The Astrophysical Journal
In order to better connect core-collapse supernova (CCSN) theory with its observational signatures, we have developed a simulation pipeline from the onset of the core collapse to beyond shock breakout from the stellar envelope.

Dramatic Rebrightening of the Type-changing Stripped-envelope Supernova SN 2023aew

The Astrophysical Journal
Multipeaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility.

Blue Supergiants in the Pinwheel Galaxy M101: Comparison with H II Region Chemical Abundances, Spectroscopic Distance, and an Independent Determination of the Hubble Constant

The Astrophysical Journal
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available at the Keck I telescope.
