Electron distributions in X-Ray plasmas: spectral diagnostics with the 3s/3d line ratio in Fe XVII
Guo-Xin Chen, Anil K. Pradhan
Efforts to benchmark astrophysical observations with X-ray laboratory measurements have been stymied by observed and measured differences of up to a factor of two in the ratio '3s/…
[O II] line ratios
Anil K. Pradhan, Maximiliano Montenegro, Sultana N. Nahar +1
Based on new calculations we reconfirm the low and high density limits on the forbidden fine structure line ratio [O II] I(3729)/I(3726): lim_{N_ e} --> 0} = 1.5 and lim_{N_ e} -->…
Studying the Variation of the Fine Structure Constant Using Emission Line Multiplets
Dirk Grupe, Anil K. Pradhan, Stephan Frank
As an extension of the method by Bahcall et al. (2004) to investigate the time dependence of the fine structure constant, we describe an approach based on new observations of forbi…
