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…
Exploring lensing signatures through spectrotemporal correlations: implications for black hole parameter estimation
Sreehari Harikesh, Shahar Hadar, Doron Chelouche
Extreme gravitational lensing and relativistic frequency shifts, combined together, imply that radiation emitted from a black hole's vicinity can echo at different frequencies and…
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 .…
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…
Reverberation mapping of high-mass and high-redshift quasars using gravitational time delays
Miriam Golubchik, Charles L. Steinhardt, Adi Zitrin +4
Mass estimates of black holes (BHs) in the centers of Active Galactic Nuclei (AGN) often rely on the radius-luminosity relation. However, this relation, usually probed by reverbera…
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…
