Context. The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy...

Context: Evolution of galaxies through cosmic time has been widely studied at high redshift, but there are a few studies in this field at lower redshifts...

This paper presents the first results of an Hα imaging survey of galaxies in the central regions of the A2151 cluster. A total of 50 sources were detected in Hα...

A search for star-forming objects belonging to tidal tails has been carried out in a sample of deep Hα images of 16 compact groups of galaxies. A total of 36...

We present a study of the H II regions in the central area of the giant irregular galaxy NGC 4449 based on observations taken on the William Herschel Telescope...

Aims:We study the two-dimensional distribution and kinematics of the stellar and gaseous components in the centre of the blue compact dwarf galaxy He 2-10. The...

Context. At high redshift, starburst galaxies present irregular morphologies with 10-20% of their star formation occurring in giant clumps. These clumpy...

In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the...

We present new spectroscopic identifications of 12 X-shaped radio galaxies and use the spectral data to derive starburst histories and masses of the nuclear...
