SPARC4 A simultaneous polarimeter and rapid camera in 4 bands
We present the basic concept of a new astronomical instrument: SPARC4 - Simultaneous Polarimeter and Rapid Camera in 4 bands. SPARC4 combines in one instrument...
Spatial Distribution of Stars, Dust and Gas in Nearby Galaxies: IFU Spectroscopy of NGC4654
We present the results and future prospects of an extensive study of the spatial distribution of stars, dust and gas in nearby galaxies, aimed at understanding...
Spatial Gradients of Old Populations in the Sculptor Dwarf Spheroidal Galaxy
We propose to observe six fields in the nearby dwarf spheroidal galaxy (dSph) Sculptor in order to study the stellar populations, and in particular their...
Spatial Structure of NGC 6822: an Example for Statistical Modeling of Astronomical Data
The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15...
Spatial variations in the star formation history of the Large Magellanic Cloud
Based on the quantitative analysis of a set of wide-field color—magnitude diagrams reaching the old main sequence-turnoffs, we present new LMC star-formation...
