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…

Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy

Wenwen Zuo, Hengxiao Guo, Jingbo Sun +25

To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, mul…

Two-Dimensional (2D) Hybrid Method: Expanding 2D Correlation Spectroscopy (2D-COS) for Time Series Analysis

Andjelka B. Kovacevic

We present a concise report on the '2DHybrid' method, an innovative extension of two-dimensional correlation spectroscopy (2D COS), tailored for quasar light curve analysis. Addres…

Bayesian synthesis of astrometric wobble and total light curves in close binary supermassive black holes

Andjelka B. Kovacevic, Yu-Yang Songsheng, Jian-Min Wang +1

We test the potential of Bayesian synthesis of upcoming multi-instrument data to extract orbital parameters and individual light curves of close binary supermassive black holes (CB…
