We present an observational study about the impacts of interactions in electron density \ion{H}{ii} regions located 7 systems interacting galaxies. The data consist long-slit spectra range 4400-7300 A, obtained with Gemini Multi-Object Spectrograph at South (GMOS). was determined using ratio emission lines [SII]6716/6731. Our results indicate that estimates HII from our sample galaxies are systematically higher than those derived for isolated mean values $N_{\rm e}=24-532$\,$ \rm cm^{-3}$,...
In this paper, we derive oxygen abundance gradients from H ii regions located in 11 galaxies eight systems of close pairs. Long-slit spectra the range 4400–7300 Å were obtained with Gemini Multi-Object Spectrograph at South (GMOS-S). Spatial profiles gaseous phase along galaxy discs using calibrations based on strong emission lines (N2 and O3N2). We found to be significantly flatter for all studied than those typical isolated spiral galaxies. Four objects our sample, AM 1219A, 1256B, 2030A...
In these proceedings we give a summary of the characteristics and current status MEGARA instrument, future optical IFU MOS for 10.4-m Gran Telescopio Canarias (GTC). is being built by Consortium public research institutions led Universidad Complutense de Madrid (UCM, Spain) that also includes INAOE (Mexico), IAA-CSIC (Spain) UPM (Spain). The two different fiber bundles, one called LCB (Large Compact Bundle) with field-of-view 12.5×11.3 arcsec<sup>2</sup> spaxel size 0.62 arcsec yielding...
We present an observational study of the impacts interactions on stellar population in a sample galaxy pairs. Long-slit spectra wavelength range 3440-7300 Å obtained with Gemini Multi-Object Spectrograph (GMOS) at South for fifteen galaxies nine close pairs were used. The spatial distributions contributions using synthesis code STARLIGHT. Taking into account different to emitted light, we found that most our are dominated by young/intermediate populations. This result differs from one...
We investigate the interaction effects in stellar and gas kinematics, population ionized properties interacting galaxy pair AM1209-292, composed by NGC4105 NGC4106. The data consist of long-slit spectra range 3000-7050 {\AA}. massive E3 presents a flat velocity profile, while is strong rotation, suggesting external origin. Its companion, NGC4106, shows asymmetries radial field, likely due to interaction. dynamics was modeled using P-Gadget3 TreePM/SPH code, from which we show that system has...
A humanidade estabelece vínculos investigativos sobre o céu há muito tempo e desde que se tem registro de suas primeiras verificações até momento, muitas coisas mudaram: conhecimento a respeito do universo expandiu, planetas outros corpos celestes foram descobertos, Sol sua relação com Terra ficaram melhor compreendidos. Com passar tempo, estabeleceram-se estudos mais difundidos na área, houve melhorias nos equipamentos pesquisa e, isso, um número maior pessoas vem atuando nesta área...
Neste trabalho, apresenta-se um estudo sobre a influência das interações na população estelar emuma amostra de pares galáxias. Foram utilizados dados espectroscopia fenda longa região espectral 3000-7000 Å, obtida com o telescópio do Gemini Sul/GMOS, para uma cinco Esses foram combinados modelos síntese populações estelares usando programa STARLIGHT. Os resultados mostraram que alguns objetos são dominados por mais jovens, idade até 500 bilhões anos e outros têm perfil ao longo disco...
