    • Spectral energy distributions of Seyfert nuclei 

      Alonso-Herrero, Almudena; Quillen, Alice C.; Rieke, George H.; Ivanov, Valentin D.; Efstathiou, Andreas (2003-07-01)
      We present nuclear spectral energy distributions (SEDs) in the range 0. 4-16 μm for an expanded CfA sample of Seyfert galaxies. The spectral indexes (fν α ν-αIR) from 1 to 16 μm range from αIR ∼ 0.9 to 3.8. The shapes of ...
    • The nonstellar infrared continuum of seyfert galaxies 

      Alonso-Herrero, Almudena; Quillen, Alice C.; Simpson, Chris J.; Efstathiou, Andreas; Ward, Martin J. (2001-03-01)
      JHKL'M (1-5 μm) imaging of a sample of Seyfert 2 galaxies is presented. We have performed an accurate estimate of the near-infrared nonstellar nuclear fluxes. We confirm that the near-infrared nuclear continuum between 1 ...
