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…
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…
First Direct Evidence for Keplerian Rotation in Quasar Inner Broad Line Regions
C. Fian, J. Jiménez-Vicente, E. Mediavilla +4
We introduce a novel method to derive rotation curves with light-day spatial resolution of the inner regions of lensed quasars. We aim to probe the kinematics of the inner part of…
Revealing the inner workings of the lensed quasar SDSS J1339+1310: Insights from microlensing analysis
C. Fian, J. A. Muñoz, J. Jiménez-Vicente +4
We aim to unveil the structure of the continuum and broad-emission line (BEL) emitting regions in the gravitationally lensed quasar SDSS J1339+1310 by examining the distinct signat…
AGN STORM 2: VIII. Investigating the Narrow Absorption Lines in Mrk 817 Using HST-COS Observations
Maryam Dehghanian, Nahum Arav, Gerard A. Kriss +39
We observed the Seyfert 1 galaxy Mrk817 during an intensive multi-wavelength reverberation mapping campaign for 16 months. Here, we examine the behavior of narrow UV absorption lin…
