10199 Chariklo (1997 CU26) is the largest Centaur so far known. We carried out near-infrared observations of this object during two different runs separated by...

We have conducted a deep multiwavelength analysis (0.15-160 μm) to study the outer region of the nearby galaxy M94. We show that the non-optical data support...

In order to characterize the low surface brightness component in blue compact dwarf galaxies, we determine their structural parameters for eight objects by...

We present broadband (gamma-ray, X-ray, near-infrared, optical, and radio) observations of the Swift gamma-ray burst (GRB) 090709A and its afterglow in an...

Aims: We aim to determine unique features that characterise the past evolution of the progenitor of the Helmi streams through the analysis of star formation...

We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC)...

The peculiar low-mass X-ray binary XSS J12270-4859, associated with the Fermi/LAT source 2FGL J1227.7-4853, was in an X-ray, gamma-ray and optical low...

We analyse the dynamical state of the galaxy clusters Abell 76 and Abell 1307 from the optical point of view, presenting a coherent scenario that responds to...

We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 μm images from the Spitzer Survey of Stellar...
