Optical identification and follow-up observations of SRGA J213151.5+491400 -- a new magnetic cataclysmic variable discovered with SRG Observatory
Ş. Balman, I. Khamitov, A. Kolbin +21
We report results of optical identification and multi-wavelength study of a new polar-type magnetic cataclysmic variable (MCV), SRGA J213151.5+491400, discovered by Spectrum Roentg…
Investigation on the Orbital Period Variations of NN Ser: Implications for the Hypothetical Planets, the Applegate Mechanism and the Orbital Stability
Aykut Özdönmez, Hüseyin ER, İlham Nasiroglu
We present 36 new mid-eclipse times obtained between 2017 and 2023 using the T100 telescope in Turkey, extending the time span of the diagram to 25 years. Once again, these n…
Analysis of the intra-night variability of BL Lacertae during its August 2020 flare
Aditi Agarwal, B. Mihov, Vipul Agrawal +7
We present an analysis of the photometry of the blazar BL Lacertae on diverse timescales from mid-July to mid-September 2020. We have used 11 different optical telescopes ar…
Galactic Model Parameters and Space Density of Cataclysmic Variables in Gaia Era: New Constraints to Population Models
R. Canbay, S. Bilir, A. Özdönmez +1
The spatial distribution, Galactic model parameters and luminosity function of cataclysmic variables (CVs) are established using re-estimated trigonometric parallaxes of {\it Gaia}…
Multi-wavelength temporal and spectral analysis of Blazar S5 1803+78
Shruti Priya, Raj Prince, A. Agarwal +3
Blazars are a class of AGN, one of their jets is pointed towards the earth. Here, we report about the multi-wavelength study for blazar S5 1803+78 between MJD 58727 to MJD 59419. W…
Galactic model parameters of cataclysmic variables: Results from a new absolute magnitude calibration with 2MASS and WISE
A. Ozdonmez, T. Ak, S. Bilir
In order to determine the spatial distribution, Galactic model parameters and luminosity function of cataclysmic variables (CVs), a -band magnitude limited sample of 263 CVs has…
