Are Boltzmann Plots of Hydrogen Balmer lines a tool for identifying a subclass of S1 AGN?
P. Rafanelli, S. Ciroi, V. Cracco +4
It is becoming clear that we can define two different types of nearby AGN belonging to the Seyfert 1 class (S1), on the basis of the match of the intensities of their Broad Balmer…
Broad spectral line and continuum variabilities in QSO spectra induced by microlensing of diffusive massive substructure
Saša Simić, Luka Č. Popović
We investigate the variability of the continuum and broad lines in QSO spectra (particularly in the H line and continuum at 5100 Å) caused by microlensing of a diffuse massi…
RXJ 0921+4529: a binary quasar or gravitational lens?
L. Č. Popović, A. V. Moiseev, E. Mediavilla +4
We report the new spectroscopic observations of the gravitational lens RXJ 021+4529 with the multi-mode focal reducer SCORPIO of the SAO RAS 6-m telescope. The new spectral observa…
Influence of gravitational microlensing on broad absorption lines of QSOs: The case of the Fe K line
Predrag Jovanović, Luka Č. Popović, Saša Simić
Here we give a brief overview of some investigations of the gravitational microlensing influence on broad absorption spectral lines of lensed QSOs. Especially, we consider the micr…
