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…

Kinematic signatures of reverberation mapping of close binaries of supermassive black holes in active galactic nuclei III. The case of elliptical orbits

Andjelka Kovacevic, Jian-Min Wang, Luka. C. Popovic

An intense search for kinematic signatures of reverberation mapping of close binary SMBH (SMBBH) is currently ongoing. Elliptical SMBBH systems (i.e. both orbits and disc-like broa…

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…
