Descripción
The far-infrared (FIR) properties of Quasi-Stellar Objects (QSOs) is
important in connecting the Starburst (SB) and Active Galactic Nucleus
(AGN) activities. Therefore, we constructed a 24 μ m selected QSO
sample to study their FIR behavior. All sources were spectroscopically
identified from MMT or the Sloan Digital Sky Survey (SDSS) as broadline
quasars. Of the total ˜330 sources, 37 have secure FIR detections
in the Herschel-HERMES field. We compared their SEDs to previous QSO
templates, and found that those FIR bright quasars differ from existing
AGNs only by an additional dust component(s). Further studies on the
origin for the FIR emission reveals the relative roles starburst and AGN
play in powering the dust emission, based on the dust temperature, FIR
luminosity, and the shapes of individual SEDs. The dust temperatures
have a wide range from 20K to 80K with a median of ˜ 30K,
indicating homogeneous heating mechanisms that could later be related to
the origin of these cold dust emissions.
