This work presents a low resolution spectroscopic data analisis of HII regions in the magellanic clouds. Nineteen nights of data over five observing seasons were analyzed to obtain the spectrums of planetary nebulae,supernova remnants, single star shells, bubbles, superbubbles and the interstellar medium. This investigation is part of the more

In this work we discuss the detection of Ly-α emitters (LAEs) through the gravitational amplification effect due to the mass in the core of the cluster of galaxies MS~2053.7-0449. We modeled the cluster using two NFW profiles, and 23 Galaxy-scale mass components as perturbations to the cluster potential. We simulate a distribution of sources for

We present the first results from the mass modelling of the Sculptor dwarf spheroidal galaxy, using spectroscopic data from our VLT/FLAMES CaII triplet wide area survey of Sculptor.

The characteristics of ionized and H I gas in the peculiar star/cluster complex in NGC 6946, obtained with the 6-m telescope (BTA) Special Astrophysical Observatory Russian Academy of Sciences (RAS), the Gemini North telescope, and the Westerbork Synthesis Radio Telescope, are presented. The complex is unusual as hosting a super star cluster, the

We present here a part of the project aimed to study the SFH in different parts of the SMC. We observed 12 fields during a four year campaign (2001-2004) using the 100-inch Irénée du Pont telescope at Las Campanas Observatory, Chile, with positions ranging from ˜1° to ˜4° from the SMC center and located at different azimuths. In this poster we
