A Possible Icy Kuiper Belt around HD 181327
Christine H. Chen, Michael P. Fitzgerald, Paul S. Smith
We have obtained a Gemini South T-ReCS Qa-band (18.3 micron) image and a Spitzer MIPS SED-mode observation of HD181327, an F5/F6V member of the ~12 Myr old beta Pictoris moving gro…
Absolute Calibration and Characterization of the Multiband Imaging Photometer for Spitzer: IV. The Spectral Energy Distribution Mode
N. Lu, P. S. Smith, C. W. Engelbracht +12
The Spectral Energy Distribution (SED) mode of the Multiband Imaging Photometer for Spitzer (MIPS) Space Telescope provides low-spectral resolution (R ~ 15-25) spectroscopy in the…
Aromatic Features in AGN: Star-Forming Infrared Luminosity Function of AGN Host Galaxies
Yong Shi, Patrick Ogle, George H. Rieke +6
We describe observations of aromatic features at 7.7 and 11.3 um in AGN of three types including PG, 2MASS and 3CR objects. The feature has been demonstrated to originate predomina…
Multiwaveband Polarimetric Observations of 15 Active Galactic Nuclei at High Frequencies: Correlated Polarization Behavior
Svetlana G. Jorstad, Alan P. Marscher, Jason A. Stevens +9
We report on multi-frequency linear polarization monitoring of 15 active galactic nuclei containing highly relativistic jets with apparent speeds from 4 to . The me…
Rapid Multiwaveband Polarization Variability in the Quasar PKS 0420-014: Optical Emission from the Compact Radio Jet
Francesca D. Darcangelo, Alan P. Marscher, Svetlana G. Jorstad +6
An 11-day monitoring campaign in late 2005 reveals clear correlation in polarization between the optical emission and the region of the intensity peak (the "pseudocore") at the ups…
9.7 um Silicate Features in AGNs: New Insights into Unification Models
Y. Shi, G. H. Rieke, D. C. Hines +6
We describe observations of 9.7 um silicate features in 97 AGNs, exhibiting a wide range of AGN types and of X-ray extinction toward the central nuclei. We find that the strength o…
