Gravity is the key engine for the evolution of the universe and the formation of its main structures: galaxies, clusters of galaxies and filaments. Gravity is...

Using deep color magnitude diagrams from HST ACS imaging, we have derived detailed star formation and chemical enrichment histories of a representative sample...

This volume documents the contributions presented at the 5th Scientific Meeting of the Spanish Astronomical Society (SEA). Covering a wide range of topics, the...

From a new mosaic image in the H-α line of the complete disc of the spiral galaxy M100, a catalogue is composed listing 1948 individual HII regions. For each...

From an H-α image of the spiral barred galaxy NGC 3359, an HII region catalogue is composed. The catalogue comprises the position, mean radius and the...

HII region catalogue of the barred galaxy NGC 7479. The catalogue contains the position, mean radius and the calibrated H-alpha luminosity of each HII region...

We propose the use of the break in the HII region luminosity function (LF) as a possible refined powerful standard candle for extragalactic distances. The...

We analyse the internal dynamics of star-forming H ii regions and their efficiency in interacting with the ISM. We have selected the nearby (4.5 Mpc) spiral...
