Mid- and far-infrared fine-structure line sensitivities to hypothetical variability of the fine-structure constant
M. G. Kozlov, S. G. Porsev, S. A. Levshakov +2
Sensitivity coefficients to temporal variation of the fine-structure constant alpha for transitions between the fine-structure (FS) sub-levels of the ground states of C I, Si I, S…
Bounds on the fine structure constant variability from FeII absorption lines in QSO spectra
Paolo Molaro, Dieter Reimers, Irina I. Agafonova +1

A new approach for testing variations of fundamental constants over cosmic epochs using FIR fine-structure lines
S. A. Levshakov, D. Reimers, M. G. Kozlov +2
Aims. To obtain limits on the variation of the fine-structure constant alpha and the electron-to-proton mass ratio mu over different cosmological epochs. Methods. A new approach ba…
