On the contribution of microlensing to X-ray variability of high-redshifted QSOs
A. F. Zakharov, L. C. Popovic, P. Jovanovic
We consider a contribution of microlensing in X-ray variability of high-redshifted QSOs. Such an effect could be caused by stellar mass objects (SMO) located in a bulge or/and in a…
The gas kinematics in Mrk 533 nucleus and circumnuclear region: a gaseous outflow
A. A. Smirnova, N. Gavrilovic, A. V. Moiseev +4
We present an analysis of 3D spectra of Mrk 533, observed with the integral-field spectrograph MPFS and using the Fabry Perot Interferometer (FPI) of the SAO RAS 6-m telescope. We…
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…
Exploring possible relations between optical variability time scales and broad emission line shapes in AGN
E. Bon, P. Jovanovic, P. Marziani +2
Here we investigate the connection of broad emission line shapes and continuum light curve variability time scales of type-1 Active Galactic Nuclei (AGN). We developed a new model…
Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics
The ATLAS Collaboration, G. Aad, E. Abat +2604
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…
Amplification and variability of the AGN X-ray emission due to microlensing
L. C. Popovic, P. Jovanovic, T. Petrovic +1
We consider the contribution of microlensing to the AGN Fe K line and X-ray continuum amplification and variation. To investigate the variability of the line and X-ray continuu…
The influence of microlensing on the shape of the AGN Fe K-alpha line
L. C. Popovic, E. G. Mediavilla, P. Jovanovic +1
We study the influence of gravitational microlensing on the AGN Fe K-alpha line confirming that unexpected enhancements recently detected in the iron line of some AGNs can be produ…
Spectroscopy and spectropolarimetry of AGN: from observations to modelling
L. C. Popovic, D. Ilic, E. Bon +10
Active galactic nuclei (AGN) are one of the most luminous objects in the Universe, emitting powerful continuum and line emission across all wavelength bands. They represent an impo…
Constraining the range of Yukawa gravity interaction from S2 star orbits III: improvement expectations for graviton mass bounds
A. F. Zakharov, P. Jovanovic, D. Borka +1
Recently, the LIGO-Virgo collaboration discovered gravitational waves and in their first publication on the subject the authors also presented a graviton mass constraint as $m_g <…
Microlensing of the Fe K line and the X-ray continuum
L. C. Popovic, P. Jovanovic, E. Mediavilla +4
The observed enhancement of the Fe K line in three gravitationally lensed QSOs (MG J0414+0534, QSO 2237+0305, H1413+117) is interpreted in terms of microlensing, even when equi…
