First detection of the 448 GHz H2O transition in space
(2017) [Artículo de periódico]We present the first detection of the ortho-H2O 423330 transition at 448 GHz in space. We observed this transition in the local (z = 0:010) luminous infrared (IR) galaxy ESO 320-G030 (IRAS F11506-3851) using the Atacama ... -
High spatial resolution of the mid-infrared emission of the Compton-thick type 2 Seyfert galaxy, Markarian 3
(2014) [Artículo 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 ... -
LLAMA : normal star formation efficiencies of molecular gas in the centres of luminous Seyfert galaxies
(2018) [Artículo de periódico]Using new Atacama Pathfinder Experiment and James Clerk Maxwell Telescope spectroscopy of the CO 2→1 line, we undertake a controlled study of cold molecular gas in moderately luminous (Lbol = 1043–44.5 erg s−1) active ... -
Polycyclic aromatic hydrocarbon and emission line ratios in active galactic nuclei and starburst galaxies
(2010) [Artículo 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) [Artículo 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 ...
