Broadening of Spectral Lines due to Dynamic Multiple Scattering and the Tully-Fisher Relation
, 1999 The frequency shift of spectral lines is most often explained by the Doppler Effect in terms of relative motion, whereas the Doppler broadening of a particular line mainly depends on the absolute temperature.

A Spectral Conjugate Gradient Method with Inexact line searches [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 In this paper, a new Spectral Conjugate Gradient (SCG) method for solving unconstrained optimization problems; based on inexact line searches is investigated. The search directions of the new CG method are always sufficient descent.

Physical Review A, 1973 © 1973 The American Physical Society ; The decay of an atom in the presence of a static perturbation is investigated. The perturbation couples a decaying state with a nondecaying state. A "hole" appears in the emission line at a frequency equal to the frequency difference between the nondecaying state and the ground state.

Deep Learning Denoising Based Line Spectral Estimation
IEEE Signal Processing Letters, 2019 Many well-known line spectral estimators may experience significant performance loss with noisy measurements. To address the problem, we propose a deep learning denoising based approach for line spectral estimation.
