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…
Constraints on the presence of platinum and gold in the spectra of the kilonova AT2017gfo
James H. Gillanders, Michael McCann, Stuart A. Sim. Stephen J. Smartt +1
Binary neutron star mergers are thought to be one of the dominant sites of production for rapid neutron capture elements, including platinum and gold. Since the discovery of the bi…
Fe III emission in quasars: evidence for a dense turbulent medium
Matthew J. Temple, Gary J. Ferland, Amy L. Rankine +5
Recent improvements to atomic energy-level data allow, for the first time, accurate predictions to be made for the Fe III line emission strengths in the spectra of luminous, $L_\te…
Polarization control of high-harmonic generation via the spin-orbit interaction
Jack Wragg, Daniel D. A. Clarke, Gregory S. J. Armstrong +3
We observe the generation of high harmonics in the plane perpendicular to the driving laser polarization and show that these are driven by the spin-orbit interaction. Using R-Matri…
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…
First evidence of enhanced recombination in astrophysical environments and the implications for plasma diagnostics
A. Nemer, N. C. Sterling, J. Raymond +6
We report the first unambiguous observational evidence of Rydberg Enhanced Recombination (RER), a potentially important recombination mechanism that has hitherto been unexplored in…
