Interaction effects on galaxy pairs with Gemini/GMOS- I: Electron density
A. C. Krabbe, D. A. Rosa, O. L. Dors +5
We present an observational study about the impacts of the interactions in the electron density of \ion{H}{ii} regions located in 7 systems of interacting galaxies. The data consis…
FM 047-02: a collisional pair of galaxies with a ring
M. Faundez-Abans, M. de Oliveira-Abans, A. C. Krabbe +3
Aims. We investigate the nature of the galaxy pair FM 047-02, which has been proposed as an archetype of the Solitaire types of peculiar (collisional) ring galaxies. Methods. The s…
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…
Optical and mid-infrared neon abundance determinations in star-forming regions
Oli L. Dors, Guillermo F. Hagele, Monica V. Cardaci +6
We employed observational spectroscopic data of star-forming regions compiled from the literature and photoionization models to analyse the neon ionic abundances obtained using bot…
A study of the remarkable galaxy system AM 546-324 (the core of Abell S0546)
M. Faúndez-Abans, A. C. Krabbe, M. Oliveira-Abans +4
We report first results of an investigation of the tidally disturbed galaxy system AM\,546-324, whose two principal galaxies 2MFGC 04711 and AM\,0546-324 (NED02) were previously cl…
X-rays as dominant excitation mechanism of [Fe ii] and H2 emission lines in active galaxies
Oli L. Dors, Rogemar A. Riffel, Monica V. Cardaci +4
We investigate the excitation mechanisms of near-infrared [Fe ii] and H2 emission lines observed in Active Galactic Nuclei (AGNs). We built a photoionization model grid considering…
