    • Gemini mid-IR polarimetry of NGC 1068: Polarized structures around the nucleus 

      Packham, Christopher C.; Young, Stuart; Fisher, Scott E.; Volk, Kevin M.; Mason, Rachel E.; Hough, James H.; Roche, Patrick F.; Elitzur, Moshe; Radomski, James T.; Perlman, Eric S. (2007-05-20)
      We present diffraction-limited, 10 μm imaging polarimetry data for the central regions of the archetypal Seyfert active galactic nucleus NGC 1068. The position angle of polarization is consistent with three dominant ...

    • The mid-infrared emission of M87 

      Perlman, Eric S.; Mason, Rachel E.; Packham, Christopher C.; Levenson, Nancy A.; Elitzur, Moshe; Schaefer, Justin J.; Imanishi, Masatoshi; Sparks, William B.; Radomski, James T. (2007-07-10)
      We discuss Subaru and Spitzer Space Telescope imaging and spectroscopy of M87 in the mid-infrared (mid-IR) from 5 to 35 μm. These observations allow us to investigate mid-IR emission mechanisms in the core of M87 and to ...

    • Science of Active Galactic Nuclei with the GTC and CanariCam 

      Levenson, Nancy A.; Packham, Christopher C.; Alonso-Herrero, Almudena; Aretxaga, Itziar; Colina, Luis; Santos, Tanio Díaz; Elitzur, Moshe; Mason, Rachel E.; Perlman, Eric S.; Radomski, James T. (2008-07-09)
      CanariCam is the facility mid-infrared (MIR) instrument for the Gran Telescopio Canarias (GTC), a 10.4m telescope at the Observatorio del Roque de los Muchachos on La Palma. One of the science drivers for CanariCam is the ...

    • Subaru spectroscopy and spectral modeling of Cygnus A 

      Merlo, Matthew J.; Perlman, Eric S.; Nikutta, Robert; Packham, Christopher C.; Elitzur, Moshe; Imanishi, Masatoshi; Levenson, Nancy A.; Radomski, James T.; Aretxaga, Itziar (2014-05-16)
      We present high angular resolution (∼0.″5) MIR spectra of the powerful radio galaxy, Cygnus A (Cyg A), obtained with the Subaru telescope. The overall shape of the spectra agree with previous high angular resolution MIR ...
