Quantitative Spectroscopy of Supernovae for Dark Energy Studies
E. Baron, David Branch, David Jeffery +6
Detailed quantitative spectroscopy of Type Ia supernovae (SNe~Ia) provides crucial information needed to minimize systematic effects in both ongoing SNe Ia observational programs s…
A Simple Bipolar Jet Model for the Polarization of Core-Collapse Supernovae
David J. Jeffery
We propose a bipolar jet model for supernova polarization. Light from the main component of the supernova (which we call the bulk supernova for short) scatters off electrons in the…
Optical Spectra of Supernovae
David Branch, E. Baron, David J. Jeffery
Supernova flux and polarization spectra bring vital information on the geometry, physical conditions, and composition structure of the ejected matter. For some supernovae the circu…
A Grey Radiative Transfer Procedure For Gamma-ray Transfer in Supernovae
David J. Jeffery
The gamma-ray transfer in supernovae for the purposes of energy deposition in the ejecta can be approximated fairly accurately as frequency-integrated (grey) radiative transfer usi…
A grey gamma-ray transfer procedure for supernovae
David J Jeffery
The gamma-ray transfer in supernovae for the purposes of energy deposition in the ejecta can be approximated as grey radiative transfer using mean opacities. In past work there is…
