Emission-Line and Continuum Reverberation Mapping of the NLS1 Galaxy WPVS 48
M. A. Probst, W. Kollatschny, M. W. Ochmann +6
WPVS 48 is a nearby narrow-line Seyfert 1 galaxy without previous analysis of the broad-line region (BLR) by means of optical spectroscopic reverberation mapping. By studying the c…
Echo mapping of the black hole accretion flow in NGC 7469
Raj Prince, Juan V. Hernández Santisteban, Keith Horne +20
Reverberation mapping (RM) can measure black hole accretion disc sizes and radial structure through observed time lags that should increase with wavelength as . Ou…
Double-peaked Ca II traces a relativistic broad-line region disk in NGC 4593
M. W. Ochmann, P. M. Weilbacher, M. A. Probst +7
Double-peaked emission lines are observed in a small percentage of active galactic nuclei (AGN). These lines allow the determination of properties of the line-emitting region, know…
Broad-Line Region Characterization in Dozens of Active Galactic Nuclei Using Small-Aperture Telescopes
Catalina Sobrino Figaredo, Doron Chelouche, Martin Haas +9
We present the results of a nearly decade-long photometric reverberation mapping (PRM) survey of the H emission line in nearby () Seyfert-Galaxies u…
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…
Evidence for gravitational self-lensing of the central supermassive black hole binary in the Seyfert galaxy NGC 1566
Wolfram Kollatschny, Doron Chelouche
It is generally accepted that all massive galaxies host supermassive black holes (BHs) in their center and that mergers of two galaxies lead to the formation of BH binaries. The mo…
