Spectroscopy and polarimetry of the gravitationally lensed quasar SDSS J1004+4112 with the 6m SAO RAS telescope
L. Č. Popović, V. L. Afanasiev, A. Moiseev +5
We present new spectroscopic and polarimetric observations of the gravitational lens SDSS J1004+4112 taken with the 6m telescope of the Special Astrophysical Observatory (SAO, Russ…
The optical variability of Supermassive Black Hole Binary Candidate PG1302-102: Periodicity and perturbation in the light curve
Andjelka B. Kovacevic, Luka C. Popovic, Sasa Simic +1
The photometric light curve of PG1302-102 shows periodic variability which makes this object one of the most plausible supermassive black hole binary candidate. Interestingly, the…
Detection of short term response of the low ionosphere on gamma ray bursts
Aleksandra Nina, Saša Simić, Vladimir A. Srećković +1
In this paper, we study the possibility of detection of short term terrestrial lower ionospheric response to gamma ray bursts (GRBs) using a statistical analysis of perturbations o…
