Energy levels and radiative rates for transitions in Cr-like Co IV and Ni V
K. M. Aggarwal, P. Bogdanovich, R. Karpuškienė +3
We report calculations of energy levels and radiative rates (-values) for transitions in Cr-like Co IV and Ni V. The quasi-relativistic Hartree-Fock (QRHF) code is adopted for c…
Stout: Cloudy's Atomic and Molecular Database
M. L. Lykins, G. J. Ferland, R. Kisielius +6
We describe a new atomic and molecular database we developed for use in the spectral synthesis code Cloudy. The design of Stout is driven by the data needs of Cloudy, which simulat…

Metastable levels in rhodium-like ions with the ground configuration and the excited configurations and are investigated. The {\sl a…
Atomic data for Zn II - Improving Spectral Diagnostics of Chemical Evolution in High-redshift Galaxies
Romas Kisielius, Varsha P. Kulkarni, Gary J. Ferland +3
Damped Lyman-alpha (DLA) and sub-DLA absorbers in quasar spectra provide the most sensitive tools for measuring element abundances of distant galaxies. Estimation of abundances fro…
