Interaction effects on galaxy pairs with Gemini/GMOS- I : electron density
Krabbe, Angela Cristina; Rosa, Deise Aparecida; Dors Júnior, Oli Luiz; Pastoriza, Miriani Griselda; Winge, Claudia; Hägelle, Guillermo Federico; Cardaci, Mónica V.; Rodrigues, Irapuan (2014) [Artigo de periódico]We present an observational study about the impacts of the interactions on the electron density of HII regions located in seven systems of interacting galaxies. The data consist of long-slit spectra in the range 4400–7300 ... -
Interaction effects on galaxy pairs with Gemini/GMOS- III : stellar population synthesis
Krabbe, Angela Cristina; Rosa, Deise Aparecida; Pastoriza, Miriani Griselda; Hägelle, Guillermo Federico; Cardaci, Mónica V.; Dors Júnior, Oli Luiz; Winge, Claudia (2017) [Artigo de periódico]We present an observational study of the impacts of interactions on the stellar population in a sample of galaxy pairs. Long-slit spectra in the wavelength range 3440–7300 Å obtained with the Gemini Multi-Object Spectrograph ... -
Interaction effects on galaxy pairs with Gemini/GMOS – II oxygen abundance gradients
Rosa, Deise Aparecida; Dors Júnior, Oli Luiz; Krabbe, Angela Cristina; Hägelle, Guillermo Federico; Cardaci, Mónica V.; Pastoriza, Miriani Griselda; Rodrigues, Irapuan; Winge, Claudia (2014) [Artigo de periódico]In this paper, we derive oxygen abundance gradients from HII regions located in 11 galaxies in eight systems of close pairs. Long-slit spectra in the range 4400–7300 Å were obtained with the Gemini Multi-Object Spectrograph ... -
Optical and mid-infrared neon abundance determinations in star-forming regions
Dors Júnior, Oli Luiz; Hägelle, Guillermo Federico; Cardaci, Mónica V.; Pérez-Montero, Enrique; Krabbe, Angela Cristina; Vilchez, Jose M.; Sales, Dinalva Aires de; Riffel, Rogério; Riffel, Rogemar André (2013) [Artigo de periódico]We have used observational spectroscopic data of star-forming regions compiled from the literature and photoionization models to analyse the neon ionic abundances obtained using both optical and mid-infrared emission lines. ...
