AGN STORM 2: X. The origin of the interband continuum delays in Mrk 817
Hagai Netzer, Michael R. Goad, Aaron J. Barth +26
The local (z=0.0315) AGN Mrk 817, was monitored over more than 500 days with space-borne and ground-based instruments as part of a large international campaign AGN STORM 2. Here, w…
On possible proxies of AGN light curves cadence selection in future time domain surveys
Andjelka B. Kovacevic, Dragana Ilic, Luka C. Popovic +6
Motivated by upcoming photometric and spectroscopic surveys (Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), Manuakea Spectroscopic Explorer), we design the stati…
LSST AGN SC Cadence Note: Two metrics on AGN variability observable
Andjelka Kovacevic, Dragana Ilic, Isidora Jankov +5
We have developed two metrics related to AGN variability observables (time-lags, periodicity, and Structure Function (SF)) to evaluate LSST OpSim FBS 1.5, 1.6, 1.7 performance in A…
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…
