AKARI IRC 2.5-5 um Spectroscopy of Infrared Galaxies over a Wide Luminosity Range
Kohei Ichikawa, Masatoshi Imanishi, Yoshihiro Ueda +4
We present the result of a systematic infrared 2.5-5 um spectroscopic study of 22 nearby infrared galaxies over a wide infrared luminosity range (10 < log(L_IR / Lsun) < 13) obtain…
Iron K emission in type-I and type-II Active Galactic Nuclei
Claudio Ricci, Yoshihiro Ueda, Stephane Paltani +3
The narrow Fe K line is one of the main signatures of the reprocessing of X-ray radiation from the material surrounding supermassive black holes, and it has been found to be omn…
The narrow Fe K line and the molecular torus in active galactic nuclei - an IR/X-ray view
Claudio Ricci, Yoshihiro Ueda, Kohei Ichikawa +5
The narrow component of the iron K is an almost ubiquitous feature in the X-ray spectra of active galactic nuclei (AGN) and is believed to originate in neutral material, possibl…
