New Radiative and Collisional Atomic Data for Sr {\sc ii} and Y {\sc ii} with application to Kilonova modelling
Leo Mulholland, Niall McElroy, Fiona McNeill +3
The spectra of singly ionised Strontium and Yttrium (Sr {\sc ii} and Y {\sc ii}) have been proposed as identifications of certain spectral features in the AT2017gfo spectrum. With…
Nebular spectra from Type Ia supernova explosion models compared to JWST observations of SN 2021aefx
Stéphane Blondin, Luc Dessart, D. John Hillier +2
Recent JWST observations of the Type Ia supernova (SN Ia) 2021aefx in the nebular phase have paved the way for late-time studies covering the full optical to mid-infrared (MIR) wav…
Improved Fe II emission line models for AGN using new atomic datasets
A. Sarkar, G. J. Ferland, M. Chatzikos +6
Understanding the Fe II emission from Active Galactic Nuclei (AGN) has been a grand challenge for many decades. The rewards from understanding the AGN spectra would be immense, inv…
Opacity modelling of heavy-metal hot subdwarfs. Photoionization of Sr, Y and Zr
L. Fernández-Menchero, C. S. Jeffery, C. A. Ramsbottom +1
Heavy-metal hot subdwarfs (sdB and sdO) represent a small group of stars with unusually high concentrations of trans-iron elements in their atmospheres, having abundances ~ 10000 t…
PSTGF : time-independent R-Matrix atomic electron-impact code
L. Fernández-Menchero, A. C. Conroy, C. P. Ballance +4
STGF is a community code employed for outer-region R-matrix calculations, describing electron-impact collisional processes. It is widely recognised that the original version of STG…
Spectroscopic diagnostics of low-ionized iron-peak elements. Electron-impact excitation of Ni and photoionisation of Ni
Luis Fernández-Menchero, Ryan T. Smyth, Catherine A. Ramsbottom +1
The spectra from Fe-peak elements may be used to determine the temperature and density of various astrophysical objects. Determination of these quantities is underpinned by the acc…
