Photometry and dynamics of the minor mergers AM\,1228-260 and AM\,2058-381
J. A. Hernandez-Jimenez, M. G. Pastoriza, C. Bonatto +3
We investigate interaction effects on the dynamics and morphology of the galaxy pairs AM\,2058-381 and AM\,1228-260. This work is based on images and long-slit spectra obtaine…
Interaction effects on galaxy pairs with Gemini/GMOS- II: Oxygen abundance gradients
D. A. Rosa, O. L. Dors, A. C. Krabbe +5
In this paper we derived oxygen abundance gradients from HII regions located in eleven galaxies in eight systems of close pairs. Long-slit spectra in the range 4400-7300A were obta…
Probing the Circumnuclear Stellar Populations of Starburst Galaxies in the Near-infrared
N. Z. Dametto, R. Riffel, M. G. Pastoriza +3
We employ the NASA Infrared Telescope Facility's near-infrared spectrograph SpeX at 0.8-2.4m to investigate the spatial distribution of the stellar populations (SPs) in four wel…
High Spatial Resolution of the Mid-Infrared Emission of Compton-Thick Seyfert 2 Galaxy Mrk3
Dinalva A. Sales, D. Ruschel-Dutra, M. G. Pastoriza +2
Mid-infrared (MIR) spectra observed with Gemini/Michelle were used to study the nuclear region of the Compton-thick Seyfert 2 (Sy 2) galaxy Mrk 3 at a spatial resolution of 2…
Photometry and Dynamics of the Minor Merger AM1219-430 with Gemini GMOS-S
J. A. Hernandez-Jimenez, M. G. Pastoriza, I. Rodrigues +3
We present an observational study of the interaction effect on the dynamics and morphology of the minor merger AM1219-430. This work is based on r' and g' images and long-slit spec…
The effects of the interaction on the kinematics, stellar population and metallicity of AM2322-821 with Gemini/GMOS
A. C. Krabbe, M. G. Pastoriza, C. Winge +3
We present an observational study about the impacts of the interactions in the kinematics, stellar populations, and oxygen abundances of the components of the galaxy pair AM\,2322-…
