Line Profile Variability in AGNs

AIP Conference Proceedings, 2007
Most active galactic nuclei are variable sources in the optical. The delay between variations in their continuum and their emission lines gives us information about the distance of the line emitting region from the central ionizing source. The study of the line profile variations contains information on geometry and kinematics of the broad emitting ...

Wide-Line Profiling: ABSTRACT

AAPG Bulletin, 1973
A technique developed and perfected in France by Compagnie Generale de Geophysique makes it possible to record, process, and interpret reflected events originating from every direction. The field layout is the same as that for conventional, multiple-coverage, seismic-reflection profiling. The only difference is that shot points are placed along oblique

Profiles of the diffuse interstellar lines

Astrophysics and Space Science, 1972
The possibility that the diffuse interstellar lines and bands are but structure in the continuous extinction by dust grains is considered in detail. The lines are assumed to arise from impurities in the grains. Profiles of the strongest diffuse features are computed for a wide variety of host grain types and sizes, including size distributions of ...

Evaluation Methods of Line Profiles

2014
The evaluation procedures of X-ray line profiles are overviewed in this chapter. These methods can be classified into four groups, namely (1) the most simple methods that evaluate only the breadths of diffraction peaks, (2) procedures using the Fourier-transforms of line profiles for the determination of the parameters of microstructures, (3) variance ...
