Monte Carlo radiative transfer for the nebular phase of Type Ia supernovae

L. J. Shingles, S. A. Sim, M. Kromer +9

We extend the range of validity of the ARTIS 3D radiative transfer code up to hundreds of days after explosion, when Type Ia supernovae are in their nebular phase. To achieve this,…

On the Cooper Minimum in Singly ionized and Neutral Argon

O. Hassouneh, N. B. Tyndall, J. Wragg +2

We present an analysis of the appearance of the Cooper Minimum in singly ionized argon in both the photoionization cross-section (PICS) and high-harmonic generation (HHG) spectrum.…

Emission line ratios of Fe III as astrophysical plasma diagnostics

Sibasish Laha, Niall B. Tyndall, Francis P. Keenan +4

Recent state-of-the-art calculations of A-values and electron impact excitation rates for Fe III are used in conjunction with the Cloudy modeling code to derive emission line inten…

Photoionization of Co and electron-impact excitation of Co using the Dirac R-matrix method

N. B. Tyndall, C. A. Ramsbottom, C. P. Ballance +1

Modelling of massive stars and supernovae (SNe) plays a crucial role in understanding galaxies. From this modelling we can derive fundamental constraints on stellar evolution, mass…

Valence and L-shell photoionization of Cl-like Argon using R-matrix techniques

Niall Tyndall, Catherine Ramsbottom, Connor Ballance +1

Photoionization cross sections are obtained using the relativistic Dirac Atomic R-matrix Codes (DARC) for all valence and L-shell energy ranges between 27-270eV. A total of 557 lev…
