Connection between the X-ray, UV and optical emission line regions of AGNs
L. C. Popovic
In order to investigate the connection between the X-ray, UV and optical spectral line regions, we selected a sample of AGN which have the strong Fe K-alpha line and analyze the UV…
Searches of stellar mass dark matter from an analysis of variabilities of high red-shifted QSOs
A. F. Zakharov, L. C. Popovic, P. Jovanovic
We consider a contribution of microlensing to the X-ray variability of high-redshifted QSOs. Such an effect could be caused by stellar mass objects (SMO) located in a bulge or/and…
Integral Field Spectroscopy of Extended Lyman-alpha Emission from the DLA Galaxy in Q2233+131
L. Christensen, S. F. Sanchez, K. Jahnke +5
This paper presents observations of an extended Lyman-alpha emission nebula surrounding the galaxy responsible for the Damped Lyman-alpha Absorption (DLA) line in the spectrum of t…
A programme for electron-impact broadening parameter calculations of ionized rare-earth element lines
L. C. Popovic, M. S. Dimitrijevic
In order to provide atomic data needed for astrophysical investigations, a set of electron-impact broadening parameters for ionized rare-earth element lines should be calculated. W…
