In this thesis, we present a number of atomic transitions associated with three astrophysically important systems S9+, Ar2+, and Co2+. The latter is especially prominent in the study of particular classes of Supernovae (SNe). We also provide an addit

Recent state-of-the-art calculations of A-values and electron impact excitation rates for Fe III are used in conjunction with the Cloudy modeling code to derive emission line intensity ratios for optical transitions among the fine-structure levels of

Photoionization cross sections are obtained using the relativistic Dirac Atomic R-matrix Codes (DARC) for all valence and L-shell energy ranges between 27-270eV. A total of 557 levels arising from the dominant configurations 3s$^2$3p$^4$, 3s3p$^5$, 3
