Scientific interest
Subjects:
1. Active Galactic Nuclei (investigation of physical and kinematical
properties of AGN center-
see e.g.Fe II in AGNs )
2. Gravitational lenses (Influence of lensing to the QSO spectra)
MLE
3. Stark Broadening (Calculation the collisional parameters in stellar
atmospheres, see e.g. Nd II in stellar
atmospheres)
4. Gamma Ray Burst (Modeling the mechanism for creation of gamma ray
bursts)
I started my research work in the Laboratory for spectroscopy at
the Faculty
of Physics in Belgrade. The problem of stark broadening of Zn II lines
in conditions of laboratory plasma was my first topic and I defined my
MSc in this field.
Since 1992 I have been working at the Astronomical Observatory
in Belgrade on atomic processes in stellar atmospheres. Especially, I
have
investigated the stark broadening effect in stellar atmospheres and
this
has been also the subject of my PhD thesis.
In 1994 I started to investigate spectral lines of Active
Galactic
Nuclei (AGNs). I am interested in spectral line shape investigation of
AGNs and in modeling the central parts of AGNs by using emission
lines,
i.e. describing the kinematics and structure of their central parts by
using the shapes and variability of emission lines of AGNs. Also, I am interested in
gravitational lensing effect (see e.g.
here), super-massive binary systems
(super-massive binary black holes, see here ) and violent processes in the Universe as
Gamma Ray Bursts - GBRs (see e.g.here and here ) .
Recently I started to work in spectro-polarimetry, especially in the determination
of the physical properties of the broad line region in AGNs. Additionally, we
give a new method for AGN black hole measurements (see e.g.
here )
