High spatial resolution of the mid-infrared emission of the Compton-thick type 2 Seyfert galaxy, Markarian 3
(2014) [Artigo de periódico]The mid-infrared (MIR) spectra observed with Gemini/Michelle have been used to study the nuclear region of the Compton-thick type 2 Seyfert galaxy, Markarian 3 (Mrk 3), at a spatial resolution of ∼200 pc. No polycyclic ... -
Polycyclic aromatic hydrocarbon and emission line ratios in active galactic nuclei and starburst galaxies
(2010) [Artigo de periódico]We study the polycyclic aromatic hydrocarbon (PAH) bands, ionic emission lines, and mid-infrared continuum properties in a sample of 171 emission line galaxies taken from the literature plus 15 new active galactic nucleus ... -
Polycyclic aromatic hydrocarbon in the central region of the Seyfert 2 galaxy NGC 1808
(2013) [Artigo de periódico]We present mid-infrared spectra of the Seyfert 2 galaxy NGC 1808, obtained with the Gemini’s Thermal-Region Camera Spectrograph at a spatial resolution of ∼26 pc. The high spatial resolution allowed us to detect bright ... -
The compton-thick Seyfert 2 nucleus of NGC 3281 torus constraints from the 9.7μm silicate absorption
(2011) [Artigo de periódico]We present mid-infrared (mid-IR) spectra of the Compton-thick Seyfert 2 galaxy NGC 3281, obtained with the Thermal-Region Camera Spectrograph at the Gemini-South telescope. The spectra present a very deep silicate absorption ...
