Differential interferometry of close binary of supermassive black holes in an elliptical configuration
Andjelka Kovacevic, Yu-Yang Songsheng, Jian-Min Wang +1
The Very Large Telescope Interferometer (VLTI), and the Extremely Large Telescope (ELT) will be a robust astrophysics suite offering the opportunity of probing the structure and dy…
The Habitability of the Galactic Bulge
Amedeo Balbi, Maryam Hami, Andjelka B. Kovačević
We present a new investigation of the habitability of the Milky Way bulge, that expands previous studies on the Galactic Habitable Zone. We discuss existing knowledge on the abunda…
Two-dimensional correlation analysis of periodicity in active galactic nuclei time series
Andjelka B Kovacevic, Luka C. Popovic, Dragana Ilic
The active galactic nuclei (AGN) are among the most powerful sources with an inherent, pronounced and random variation of brightness. The randomness of their time series is so subt…
Confirmed short periodic variability of subparsec supermassive binary black hole candidate Mrk 231
Andjelka B. Kovacevic, Tignfeng Yi, Xinyu Dai +3
Here we confirm the short periodic variability of a subparsec supermassive binary black hole (SMBBH) candidate Mrk 231 in the extended optical photometric data set collected by the…
Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395
Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31
We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…
