Molecular Hydrogen and [Fe II] in Active Galactic Nuclei III: LINERS and Star Forming Galaxies
R. Riffel, A. Rodriguez-Ardila, I. Aleman +4
We study the kinematics and excitation mechanisms of H2 and [Fe II] lines in a sample of 67 emission-line galaxies with Infrared Telescope Facility SpeX near-infrared (NIR, 0.8-2.4…
A correlation between the stellar and [Fe II] velocity dispersions in Active Galaxies
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Rogerio Riffel +8
We use near-infrared spectroscopic data from the inner few hundred parsecs of a sample of 47 active galaxies to investigate possible correlations between the stellar velocity dispe…
Intermediate age stars as origin of the low velocity dispersion nuclear ring in Mrk1066
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Rogerio Riffel +1
We report the first two-dimensional stellar population synthesis in the near-infrared of the nuclear region of an active galaxy, namely Mrk1066. We have used integral field spectro…
The lenticular galaxy NGC3607: stellar population, metallicity and ionised gas
Mauro G. Rickes, Miriani G. Pastoriza, Charles Bonatto
In this work we derive clues to the formation scenario and ionisation source of the lenticular galaxy NGC 3607 by means of metallicity gradients, stellar population and emission li…
