Spitzer IRS spectra of a large sample of Seyfert galaxies: A Variety of infrared SEDs in the local AGN population
(Astronomical Journal, 2006-07)
We are conducting a large observing program with the Spitzer Space Telescope to determine the mid-to-far infrared spectral energy distributions of a well-defined sample of 87 nearby, 12 µm-selected Seyfert galaxies. In ...
The NICMOS polarimetric calibration
(University of Chicago Press: Publications of the Astronomical Society of the Pacific, 2006-04-27)
The value of accurately knowing the absolute calibration of the polarizing elements in the Near
Infrared Camera and Multi-Object Spectrometer (NICMOS) becomes especially important when conducting studies which require ...
The jet and circumnuclear environment of 3C 293
(Astrophysical Journal, 2006-03-01)
We present the new HST near-infrared polarimetry, broad and narrow-band imaging,
and MERLIN 4.5GHz Multi-Frequency Synthesis radio imaging of 3C 293, a unique radio galaxy whose host is an obvious merger remnant, in an ...
The warped nuclear disk of radio galaxy 3C 449
(Astrophysical Journal, 2006)
Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlier to this statistical
majority, as it ...
