Microlensing analysis of 14.5-year light curves in SDSS J1004+4112: Quasar accretion disk size and intracluster stellar mass fraction
R. Forés-Toribio, J. A. Muñoz, C. Fian +2
Context. The gravitational lens system SDSS J1004+4112 was the first known example of a quasar lensed by a galaxy cluster. The interest in this system has been renewed following th…
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…
AGN STORM 2. VII. A Frequency-resolved Map of the Accretion Disk in Mrk 817: Simultaneous X-ray Reverberation and UVOIR Disk Reprocessing Time Lags
Collin Lewin, Erin Kara, Aaron J. Barth +35
X-ray reverberation mapping is a powerful technique for probing the innermost accretion disk, whereas continuum reverberation mapping in the UV, optical, and infrared (UVOIR) revea…
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…
AGN STORM 2: IX. Studying the Dynamics of the Ionized Obscurer in Mrk 817 with High-resolution X-ray Spectroscopy
Fatima Zaidouni, Erin Kara, Peter Kosec +45
We present the results of the XMM-Newton and NuSTAR observations taken as part of the ongoing, intensive multi-wavelength monitoring program of the Seyfert 1 galaxy Mrk 817 by the…
Single-epoch and Differential Astrometric Microlensing of Quasars
R. Forés-Toribio, E. Mediavilla, J. A. Muñoz +3
We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing). O…
