Evidence for a moderate spin from X-ray reflection of the high-mass supermassive black hole in the cluster-hosted quasar H1821+643
Júlia Sisk-Reynés, Christopher S. Reynolds, James H. Matthews +1
We present an analysis of deep Low-Energy and High-Energy Transmission Grating archival observations of the extraordinarily luminous radio-quiet quasar H1821+643, hosted…
New constraints on light Axion-Like Particles using Chandra Transmission Grating Spectroscopy of the powerful cluster-hosted quasar H1821+643
Júlia Sisk Reynés, James H. Matthews, Christopher S. Reynolds +3
Axion-Like Particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular t…
Probing the circumnuclear environment of NGC1275 with High-Resolution X-ray spectroscopy
Christopher S. Reynolds, Robyn N. Smith, Andrew C. Fabian +6
NGC1275 is the Brightest Cluster Galaxy (BCG) in the Perseus cluster and hosts the active galactic nucleus (AGN) that is heating the central 100\,kpc of the intracluster medium (IC…
Discovery of an X-ray Quasar Wind Driving the Cold Gas Outflow in the Ultraluminous Infrared Galaxy IRAS F05189-2524
Robyn N. Smith, Francesco Tombesi, Sylvain Veilleux +2
We present new XMM-Newton and NuSTAR observations of the galaxy merger IRAS F05189-2524 which is classified as an ultra-luminous infrared galaxy (ULIRG) and optical Seyfert 2 at $z…
Astrophysical limits on very light axion-like particles from Chandra grating spectroscopy of NGC 1275
Christopher S. Reynolds, M. C. David Marsh, Helen R. Russell +4
Axions/axion-like particles (ALPs) are a well motivated extension of the Standard Model and are generic within String Theory. The X-ray transparency of the intracluster medium (ICM…
The Sloan Digital Sky Survey Reverberation Mapping Project: H and H Reverberation Measurements From First-year Spectroscopy and Photometry
C. J. Grier, J. R. Trump, Yue Shen +39
We present reverberation mapping results from the first year of combined spectroscopic and photometric observations of the Sloan Digital Sky Survey Reverberation Mapping Project. W…
Radio Jet Feedback and Star Formation in Heavily Obscured Quasars at Redshifts ~0.3-3, I: ALMA Observations
Carol J. Lonsdale, Mark Lacy, Amy E. Kimball +17
We present ALMA 870 micron (345 GHz) data for 49 high redshift (0.47<z<2.85), luminous (11.7 < log L(bol) (Lsun) < 14.2) radio-powerful AGN, obtained to constrain cool dust emissio…
The Sloan Digital Sky Survey Reverberation Mapping Project: Technical Overview
Yue Shen, W. N. Brandt, Kyle S. Dawson +36
The Sloan Digital Sky Survey Reverberation Mapping project (SDSS-RM) is a dedicated multi-object RM experiment that has spectroscopically monitored a sample of 849 broad-line quasa…
