X-ray Winds In Nearby-to-distant Galaxies (X-WING) - I: Legacy Surveys of Galaxies with Ultrafast Outflows and Warm Absorbers in -
Satoshi Yamada, Taiki Kawamuro, Misaki Mizumoto +10
As an inaugural investigation under the X-ray Winds In Nearby-to-distant Galaxies (X-WING) program, we assembled a dataset comprising 132 active galactic nuclei (AGNs) spanning red…
BASS XLII: The relation between the covering factor of dusty gas and the Eddington ratio in nearby active galactic nuclei
C. Ricci, K. Ichikawa, M. Stalevski +25
Accreting supermassive black holes (SMBHs) located at the center of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circu…
BAT AGN Spectroscopic Survey - V. X-ray properties of the Swift/BAT 70-month AGN catalog
Claudio Ricci, Benny Trakhtenbrot, Michael J. Koss +18
Hard X-ray ( keV) observations of Active Galactic Nuclei (AGN) can shed light on some of the most obscured episodes of accretion onto supermassive black holes. The 70-mont…
Compton-thick Accretion in the local Universe
C. Ricci, Y. Ueda, M. J. Koss +3
Heavily obscured accretion is believed to represent an important stage in the growth of supermassive black holes, and to play an important role in shaping the observed spectrum of…
A Compton thick AGN in the barred spiral NGC 4785
P. Gandhi, S. Yamada, C. Ricci +5
We present X-ray observations of the active galactic nucleus (AGN) in NGC 4785. The source is a local Seyfert 2 which has not been studied so far in much detail. It was recently de…
Infrared and hard X-ray diagnostics of AGN identification from the Swift/BAT and AKARI all-sky surveys
Keiko Matsuta, Poshak Gandhi, Tadayasu Dotani +8
We combine data from two all-sky surveys in order to study the connection between the infrared and hard X-ray (>10keV) properties for local active galactic nuclei (AGN). The Swift/…
