Oscillatory Line-Driven Winds: The Role of Atmospheric Stratification
Joshua Key, Daniel Proga, Randall Dannen +2
Time-dependent numerical studies of line-driven winds using the Sobolev approximation have a history spanning over three decades. In many of these studies, the wind solutions displ…
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…
Position dependent radiation fields near accretion disks
Kara Smith, Daniel Proga, Randall Dannen +2
In disk wind models for active galactic nuclei (AGN) outflows, high-energy radiation poses a significant problem wherein the gas can become overionized, effectively disabling what…
AGN STORM 2: V. Anomalous Behavior of the CIV Light Curve in Mrk 817
Y. Homayouni, Gerard A. Kriss, Gisella De Rosa +49
An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant vari…
Coordinated X-ray and UV absorption within the accretion disk wind of the active galactic nucleus PG 1126-041
M. Giustini, P. Rodríguez Hidalgo, J. N. Reeves +14
Accretion disk winds launched close to supermassive black holes (SMBHs) are a viable mechanism to provide feedback between the SMBH and the host galaxy. We aim to characterize the…
