Numerical simulations predict that metal-poor gas accretion from the cosmic web fuels the formation of disk galaxies. This paper discusses how cosmic gas...
Star formation trends in high-redshift galaxy surveys: the elephant or the tail?
Star formation rate and accumulated stellar mass are two fundamental physical quantities that describe the evolutionary state of a forming galaxy. Two recent...
Star Formation Triggering by Density Waves in the Grand Design Spirals NGC 3992 and NGC 628
Although spiral structure in grand design galaxies is generally present in the young and old stellar components and also in both atomic and molecular gas, the...
Star-forming galaxies at low-redshift in the SHARDS survey
Context. The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy...
Star-forming galaxies in SDSS: signs of metallicity evolution
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...
Star-Forming Galaxies in the Hercules Cluster: Hα Imaging of A2151
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...
Star-forming Objects in the Tidal Tails of Compact Groups
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...
Star-forming Regions in the Irregular Galaxy NGC 4449: Determination of Their Integrated Parameters
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...
Star-gas decoupling and a non-rotating stellar core in He 2-10. Integral field spectroscopy with FLAMES/ARGUS
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...
