On Atomic Line Opacities for Modeling Astrophysical Radiative Transfer
Jonathan Morag
In astrophysics, atomic transition line opacity is a primary source of uncertainty in theoretical calculations of radiative transfer. Much of this uncertainty is dominated by the i…

Radiation Mediated Shock and Planar Shock Breakout in the Presence of Atomic Transition Lines
Jonathan Morag
We numerically study fast Newtonian radiation mediated shocks (RMS - v/c~0.2) in two simplified problems in the context of supernova shock breakout; (1) An RMS traveling in a unifo…

Shock-cooling Constraints via Early-time Observations of the Type IIb SN 2022hnt
Joseph R. Farah, D. Andrew Howell, Giacomo Terreran +8
We report the results of a rapid follow-up campaign on the Type IIb Supernova (SN) 2022hnt. We present a daily, multi-band, photometric follow-up using the Las Cumbres Observatory,…
