PublicaciónThe nuclear dust lane of Circinus: collimation without a torus
In some AGN, nuclear dust lanes connected to kpc-scale dust structures provide all the extinction required to obscure the nucleus, challenging the role of the...

PublicaciónThe Nuclear Infrared Emission of Low-luminosity Active Galactic Nuclei
We present high-resolution mid-infrared (MIR) imaging, nuclear spectral energy distributions (SEDs), and archival Spitzer spectra for 22 low-luminosity active...
