    • 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 ...
    • New insights into the study of magnetic field in the clumpy torus of AGN using near-infrared polarimetry 

      López Rodríguez, Enrique; Packham, Christopher C.; Young, Stuart; Elitzur, Moshe; Levenson, Nancy A.; Mason, Rachel E.; Ramos Almeida, Christina; Alonso-Herrero, Almudena; Jones, Terry Jay; Perlman, Eric S. (2013-10-24)
      We present J, H and K., imaging polarimetry of IC5063. N1R polarimetry observations may advance our understanding of the mechanisms of polarisation and hence magnetic field strength in the torus of AGN. In these proceedings ...
    • 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 ...
