Joint NuSTAR and Chandra analysis of the obscured quasar in IC 2497 - Hanny's Voorwerp system
Lia F. Sartori, Kevin Schawinski, Michael J. Koss +9
We present new Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the core of IC 2497, the galaxy associated with Hanny's Voorwerp. The combined fits of the Chandra (0.…
BAT AGN Spectroscopic Survey--VIII. Type 1 AGN With Massive Absorbing Columns
T. Taro Shimizu, Richard I. Davies, Michael Koss +12
We explore the relationship between X-ray absorption and optical obscuration within the BAT AGN Spectroscopic Survey (BASS) which has been collecting and analyzing the optical and…
LLAMA: Normal star formation efficiencies of molecular gas in the centres of luminous Seyfert galaxies
D. J. Rosario, L. Burtscher, R. I. Davies +23
Using new APEX and JCMT spectroscopy of the CO 2-1 line, we undertake a controlled study of cold molecular gas in moderately luminous Active Galactic Nuclei (AGN) and inactive gala…
LLAMA: Nuclear stellar properties of Swift BAT AGN and matched inactive galaxies
Ming-Yi Lin, R. I. Davies, E. K. S. Hicks +20
In a complete sample of local 14-195 keV selected AGNs and inactive galaxies, matched by their host galaxy properties, we study the spatially resolved stellar kinematics and lumino…
Investigating the evolution of the dual AGN system ESO~509-IG066
P. Kosec, M. Brightman, D. Stern +13
We analyze the evolution of the dual AGN in ESO 509-IG066, a galaxy pair located at z=0.034 whose nuclei are separated by 11 kpc. Previous observations with XMM-Newton on this dual…
The close environments of accreting massive black holes are shaped by radiative feedback
Claudio Ricci, Benny Trakhtenbrot, Michael J. Koss +13
The large majority of the accreting supermassive black holes in the Universe are obscured by large columns of gas and dust. The location and evolution of this obscuring material ha…
