Ce II-IV emission in kilonovae with R-matrix collision strengths and distorted wave recombination rates
Leo Patrick Mulholland, Niamh Ferguson, Luke J. Shingles +3
We provide transition probabilities and Maxwellian-averaged collision-strengths for the electron-impact excitation of Ce {\sc ii} - {\sc iv}. These ions are potentially abundant in…
Electron impact excitation of Te IV and V and Level Resolved R-matrix Photoionization of Te I - IV with application to modelling of AT2017gfo
Leo P. Mulholland, Catherine A. Ramsbottom, Connor P. Ballance +2
Spectral modelling of kilonovae (KNe) require large amounts of collisional excitation and photoionization atomic data for lowly ionised (neutral, singly and doubly ionised) species…
New Level Resolved Ground and Excited State Pb III, IV, V & VI Photoionization Cross Sections for Heavy Metal Subdwarf Modeling
David J. Dougan, Matti Dorsch, Laura J. A. Scott +3
High abundances of various lead (Pb) species have been identified in the spectra of many Asymptotic Giant Branch (AGB) stars and O- and B-type subdwarfs (sdO/B). Additional atomic…
Strontium I, III, IV and V: Electron Impact Excitation Data for Kilonovae and White Dwarf Diagnostic Applications
David J. Dougan, Niall E. McElroy, Connor P. Ballance +1
Strontium (Sr) emissions have been observed across a wide range of astrophysical phenomena, from kilonovae (KNe) events to white dwarf (WD) stars. Precise and extensive atomic data…
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…
On the use of the Axelrod formula for thermal electron collisions in Astrophysical Modelling
Leo P. Mulholland, Steven J. Bromley, Connor P. Ballance +2
The Axelrod approximation is widely used in astrophysical modelling codes to evaluate electron-impact excitation effective collision strengths for forbidden transitions. Approximat…
Collisional and Radiative Data for Tellurium ions in Kilonovae modelling and Laboratory Benchmarks
Leo Patrick Mulholland, Fiona McNeill, Stuart A. Sim +2
Tellurium is a primary candidate for the identification of the 2.1 m emission line in kilonovae (KNe) spectra AT2017gfo and GRB230307A. Despite this, there is currently an insuf…
