Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec
Xiangyu Jin, Jinyi Yang, Feige Wang +19
We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…
AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817
John W. Montano, Aaron J. Barth, Keith Horne +40
We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…
Cepheid-based Distances to NGC 4303 and NGC 1068
Madison Markham, Misty C. Bentz, Laura Ferrarese +2
We present Cepheid-based distances to two canonical AGN: NGC 4303 (M 61) and NGC 1068. Data were obtained using the Hubble Space Telescope with nonredundant time spacing over 12 vi…
Modelling the AGN broad line region using single-epoch spectra II. Nearby AGN
S. I. Raimundo, M. Vestergaard, M. R. Goad +4
The structure of the broad line region (BLR) is an essential ingredient in the determination of active galactic nuclei (AGN) virial black hole masses, which in turn are important t…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
The extended High A(V) Quasar Survey: Searching for dusty absorbers toward mid-infrared selected quasars
J. -K. Krogager, J. P. U. Fynbo, K. E. Heintz +6
We present the results of a new spectroscopic survey for dusty intervening absorption systems, particularly damped Ly absorbers (DLAs), towards reddened quasars. The candidate q…
