AGN STORM 2. VI. Mapping Temperature Fluctuations in the Accretion Disk of Mrk 817

Jack M. M. Neustadt, Christopher S. Kochanek, John Montano +49

We fit the UV/optical lightcurves of the Seyfert 1 galaxy Mrk 817 to produce maps of the accretion disk temperature fluctuations resolved in time and radius. The maps are…

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…

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…

A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z=6.61 Quasar

Feige Wang, Jinyi Yang, Joseph F. Hennawi +56

We present the first results from the JWST ASPIRE program (A SPectroscopic survey of biased halos In the Reionization Era). This program represents an imaging and spectroscopic sur…

A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): A First Look at the Rest-frame Optical Spectra of Quasars Using JWST

Jinyi Yang, Feige Wang, Xiaohui Fan +53

Studies of rest-frame optical emission in quasars at have historically been limited by the wavelengths accessible by ground-based telescopes. The James Webb Space Telescope (…

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…
