In the last years star-forming regions and massive protostars have been suggested to be gamma-ray emitters. Isolated massive protostars present powerful...
Gas accretion from the cosmic web in the local Universe
Numerical simulations predict that gas accretion from the cosmic web drives star formation in disks galaxies. The process is important in low mass haloes ( 1012...
GLACE survey: Galaxy activity in ZwCl0024+1652 cluster from strong optical emission lines
Although ZwCl0024+1652 galaxy cluster at z ∼ 0.4 has been thoroughly analysed, it lacks a comprehensive study of star formation and nuclear activity of its...
GLACE survey: OSIRIS/GTC tuneable filter Hα imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z = 0.395. I. Survey presentation, TF data reduction techniques, and catalogue
The cores of clusters at 0 ≲ z ≲ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters...
GLACE survey: OSIRIS/GTC tuneable imaging of the galaxy cluster ZwCl 0024.0+1652. II. The mass-metallicity relationship and the effect of the environment
Aims: In this paper, we revisit the data for the galaxy cluster ZwCl 0024.0+1652 provided by the GLACE survey and study the mass-metallicity function and its...
Global morphology and physical relations between the stars, gas and dust in the disc and arms of M100.
We study star formation processes in the disc of the weakly barred grand design spiral galaxy M100 (NGC 4321) from a variety of images tracing recent massive...
Globular cluster ejection, infall, and the host dark matter halo of the Pegasus dwarf galaxy
Recent photometric observations revealed a massive, extended (M GC ≳ 10 5 M ☉; R h ̃ 14 pc) globular cluster (GC) in the central region (D 3D ≲ 100 pc) of the...
Globular clusters systems and their host dark matter halos
In the Λ-CDM galaxy formation paradigm, the star formation history of a galaxy is coupled to the total mass of its dark matter halo through processes like...
GOYA Survey: U and B Number Counts in the Groth-Westphal Strip
We present U and B galaxy number counts from a field that comprises a 0.29 square degrees area of sky, and which covers the Groth-Westphal Strip (Groth et al...
