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…
AGN STORM 2. IV. Swift X-ray and ultraviolet/optical monitoring of Mrk 817
Edward M. Cackett, Jonathan Gelbord, Aaron J. Barth +48
The AGN STORM 2 campaign is a large, multiwavelength reverberation mapping project designed to trace out the structure of Mrk 817 from the inner accretion disk to the broad emissio…
AGN STORM 2. III. A NICER view of the variable X-ray obscurer in Mrk 817
Ethan R. Partington, Edward M. Cackett, Erin Kara +44
The AGN STORM 2 collaboration targeted the Seyfert 1 galaxy Mrk 817 for a year-long multiwavelength, coordinated reverberation mapping campaign including HST, Swift, XMM-Newton, NI…
AGN STORM 2: I. First results: A Change in the Weather of Mrk 817
Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69
We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…
The Sloan Digital Sky Survey Reverberation Mapping Project: UV-Optical Accretion Disk Measurements with Hubble Space Telescope
Y. Homayouni, Megan R. Sturm, Jonathan R. Trump +10
We present accretion-disk structure measurements from UV-optical reverberation mapping observations of a sample of eight quasars at 0.24<z<0.85. Ultraviolet photometry comes from t…
The X-ray Spectrum and Spectral Energy Distribution of FIRST J155633.8+351758: a LoBAL Quasar with a Probable Polar Outflow
Robert C. Berrington, Michael S. Brotherton, Sarah C. Gallagher +8
We report the results of a new 60 ks Chandra X-ray Observatory Advanced CCD Imaging Spectrometer S-array (ACIS-S) observation of the reddened, radio-selected, highly polarized `FeL…
