Excitation and Recombination Data for Nd I-V with Applications to Kilonovae

N. Ferguson, L. P. Mulholland, M. McCann +2

Neodymium (Nd), a key r-process element, significantly influences the opacity and emergent spectra of kilonovae resulting from neutron star mergers. We present new atomic data for…

Late-time emission-line profiles from kilonova models

S. A. Sim, O. Just, Z. Xiong +10

Numerical simulations suggest that neutron star mergers eject material with complex, non-spherical density and composition distributions. Here we use two-dimensional configurations…

Strontium and helium in the kilonova AT2017gfo: Origin of the 1μm feature constrained via NLTE calculations

Aayush Arya, Rasmus Damgaard, Albert Sneppen +4

Mergers of neutron stars are believed to be one of the primary sites for the synthesis of the universe's heavy elements via the rapid neutron capture process. AT2017gfo, the kilono…

Electron-Impact Excitation of Zirconium I-III in support of Neutron Star Merger Diagnostics

M. McCann, C. P. Ballance, F. McNeill +2

Recent observation and analysis of kilonovae (KNe) spectra as a result of neutron star mergers require accurate and complete atomic structure and collisional data for interpretatio…

Luminosity predictions for the first three ionisation stages of W, Pt and Au to probe potential sources of emission in kilonova

M. McCann, L. P. Mulholland, Z. Xiong +7

A large number of R-matrix calculations of electron impact excitation for heavy elements (Z > 70) have been performed in recent years for applications in fusion and astrophysics re…

Identification of new gold lines in the 350 to 1000 nm spectral region using laser produced plasmas

M. Charlwood, S. Chaurasia, M. McCann +3

We present results from a pilot study, using a laser-produced plasma, to identify new lines in the 350 to 1000 nm spectral region for the r-process element gold (Au), of relevance…

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,…
