Characterizing the Rapid Hydrogen Disappearance in SN 2022crv: Evidence of a Continuum between Type Ib and IIb Supernova Properties

open access: yesThe Astrophysical Journal
We present optical and near-infrared (NIR) observations of SN 2022crv, a stripped-envelope supernova in NGC 3054, discovered within 12 hr of explosion by the Distance Less Than 40 Mpc Survey.

Optical and Near-infrared Nebular-phase Spectroscopy of SN 2024ggi: Constraints on the Structure of the Inner Ejecta, Progenitor Mass, and Dust

open access: yesThe Astrophysical Journal
We present optical and near-infrared (NIR) spectroscopic observations of the nearby Type II supernova SN 2024ggi ranging from 250 to 581 days after the explosion.

Nucleosynthesis in Core-Collapse Supernovae

open access: yes, 2018
The nucleosynthesis which occurs in core-collapse supernovae (CCSN) is one of the most important sources of elements in the universe. Elements from Oxygen through Iron come predominantly from supernovae, and contributions of heavier elements are also ...

Prompt Convection in Core Collapse Supernovae

open access: yes, 1994
We investigate prompt convection in core collapse supernovae and its consequences for the late-time shock evolution and supernova outcome. We examine the evolution of the core prior to the onset of convection and find that the negative entropy gradients ...

Hubble Space Telescope Deep Upper Limits Rule out a Surviving Massive Binary Companion to the Type Ic Supernova 2012fh

open access: yesThe Astrophysical Journal
Current explanations of the mass-loss mechanism for stripped-envelope supernovae (SNe) remain divided between single and binary progenitor systems. Here we obtain deep ultraviolet (UV) imaging with the Hubble Space Telescope (HST) of the Type Ic SN ...

Enabling Early Transient Discovery in LSST via Difference Imaging with DECam

open access: yesThe Astrophysical Journal Letters
We present SLIDE , a pipeline that enables transient discovery in data from the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST), using archival images from the Dark Energy Camera as templates for difference imaging.

SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae

open access: yesThe Astrophysical Journal
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 2023taz, in a dwarf galaxy at z = 0.407.
