    • The differences in the torus geometry between hidden and non-hidden broad line active galactic nuclei 

      Ichikawa, Kohei; Packham., Christopher C; Almeida, Cristina Ramos; Ramos, Andrés Asensio; Alonso-Herrero, Almudena; González-Martín, Omaira; López Rodríguez, Enrique; Ueda, Yoshihiro; Díaz-Santos, Tanio; Perlman, Eric S. (2015-04-20)
      We present results from the fitting of infrared (IR) spectral energy distributions of 21 active galactic nuclei (AGNs) with clumpy torus models. We compiled high spatial resolution (∼0.3–0.7 arcsec) mid-IR (MIR) ...
    • Infrared polarimetry of Mrk 231: Scattering off hot dust grains in the central core 

      López Rodríguez, Enrique; Packham, Christopher C.; Jones, Terry Jay; Siebenmorgen, Ralf; Roche, Patrick F.; Levenson, Nancy A.; Alonso-Herrero, Almudena; Perlman, Eric S.; Ichikawa, Kohei; Ramos Almeida, Christina (2016-09-30)
      We present high-angular (0.17-0.35 arcsec) resolution imaging polarimetric observations of Mrk 231 in the 3.1 μm filter using MMT-Pol on the 6.5-m MMT, and in the 8.7, 10.3, and 11.6 μm filters using CanariCam on the 10.4-m ...
    • Polarized mid-infrared synchrotron emission in the core of Cygnus A 

      López Rodríguez, Enrique; Packham, Christopher C.; Tadhunter, Clive N.; Mason, Rachel E.; Perlman, Eric S.; Alonso-Herrero, Almudena; Ramos Almeida, Cristina; Ichikawa, Kohei; Levenson, Nancy A.; Rodríguez-Espinosa, José Miguel (2014-10-01)
      We present high-angular (∼0". 4) resolution mid-infrared (MIR) polarimetric observations in the 8.7μm and 11.6μm filters of Cygnus A using CanariCam on the 10.4 m Gran Telescopio CANARIAS. A highly polarized nucleus ...
