The first results of an analysis of the spatial variations along and across the ENLR of NGC 4151 are presented. The excitation of the gas clearly decreases with...

Recently, huge photometric databases are being obtained for the Magellanic Clouds and other Local Group galaxies. These data allow, not only to study in great...

Massive galaxies experienced an enormous structural evolution in the last ten billion years. The most viable explanation is that massive galaxies have undergone...

The ability of any Machine Learning method to classify the spectra of galaxies depending on the properties of the stellar component rests on the information...

We are obtaining deep multiwavelength data of a sample of nearby blue compact dwarf galaxies (BCDGs) combining broad-band optical/NIR and Hα photometry, optical...

We are currently performing a new analysis of the close environment of star-forming dwarf galaxies and its effects on their star-forming activity. For a sample...

The energy emission involved in a Gamma-Ray Burst evidently can be estimated only provided that we know the distance to the source. The same is true for the...

The study of the Extremly Red Objects (EROs), is the importance for setting constraints on the first epoch of massive galaxy formation, for exploring the...
