Here we present the methodology we have devised to study the spatial distribution of Massive Star Formation in galaxies. We show results of our analysis performed on a sample of 4,503 galaxies in a range of redshifts extending up to z˜1.2, in the Chandra Deep Field South. We use data from GOODS-HST and COMBO17. The aim is to produce techniques

The purpose of this work is to quantify the ionizing photon budget in the HII regions, deriving the fraction of the Lyman continuum (Lyc) absorbed by dust or escaping from the regions. An underlying aim is to explore the degree of inhomogeneity of a typical HII region.

Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are quite rare at present, minor mergers and satellite disruptions-which result in stellar streams-should be common, and are indeed seen in both the Milky Way and the Andromeda Galaxy. As a

We study a sample of 20 galaxies with an observed central drop in the stellar velocity dispersion (σ-drop) matched with a control sample of galaxies without a σ-drop. We search for correlations between σ-drops and the properties, primarily morphological, of the inner zones and discs of their host galaxies. Both morphological parameters and

Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a search for isolated planetary-mass objects in the 3 Myr-old star-forming region IC 348. Methods: Deep, narrowband CH4off and CH4on images were obtained with CFHT/WIRCam over 0.11 sq. deg
