Searching for Cool Dust in the Mid-to-far Infrared: The Mass-loss Histories of the Hypergiants µ Cep, VY CMa, IRC+10420, and ρ Cas
Gehrz, Robert D.; Humphreys, Roberta M.; Jones, Terry J. +6 more
We present mid- and far-IR imaging of four famous hypergiant stars: the red supergiants µ Cep and VY CMa, and the warm hypergiants IRC +10420 and ρ Cas. Our 11-37 µm SOFIA/FORCAST imaging probes cool dust not detected in visual and near-IR imaging studies. Adaptive optics 8-12 µm imaging of µ Cep and IRC +10420 with MMT/MIR…
Star Formation in 3CR Radio Galaxies and Quasars at z < 1
Wilkes, Belinda J.; Willner, S. P.; Haas, Martin +8 more
Using the Herschel Space Observatory we have observed a representative sample of 87 powerful 3CR sources at redshift z\lt 1. The far-infrared (FIR, 70-500 µm) photometry is combined with mid-infrared (MIR) photometry from the Wide-Field Infrared Survey Explorer and cataloged data to analyze the complete spectral energy distributions (SEDs) o…
