Herschel Survey of the Palomar-Green QSOs at Low Redshift
Ho, Luis C.; Scoville, Nicholas Z.; Petric, Andreea O. +1 more
We investigate the global cold dust properties of 85 nearby (z≤slant 0.5) QSOs, chosen from the Palomar-Green sample of optically luminous quasars. We determine their infrared spectral energy distributions and estimate their rest-frame luminosities by combining Herschel data from 70 to 500 µm with near-infrared and mid-infrared measurements …
The AKARI 2.5-5.0 µm Spectral Atlas of Type-1 Active Galactic Nuclei: Black Hole Mass Estimator, Line Ratio, and Hot Dust Temperature
Nakagawa, Takao; Oyabu, Shinki; Ohyama, Youichi +11 more
We present 2.5-5.0 µm spectra of 83 nearby (0.002 < z < 0.48) and bright (K < 14 mag) type-1 active galactic nuclei (AGNs) taken with the Infrared Camera on board AKARI. The 2.5-5.0 µm spectral region contains emission lines such as Brβ (2.63 µm), Brα (4.05 µm), and polycyclic aromatic hydrocarbons (3.3 µm), …
