Context. Among the blazars whose emission has been detected up to very high-energy (VHE; 100 GeV

We report the results of near-infrared Very Large Telescope (VLT)-Infrared Spectrometer and Array Camera (ISAAC) spectroscopy of a sample of 12 galaxies at z=0...

We present Very Small Array (VSA) observations (centred on ~34 GHz) on scales ~20 arcmin towards a complete, X-ray flux-limited sample of seven clusters at...

We continue the development of our Voronoi Galaxy Cluster Finder (VGCF) technique by applying it to galaxy catalogs obtained with B and R band observations of...

Context. QSO B1420+326 is a blazar classified as a flat-spectrum radio quasar (FSRQ). At the beginning of the year 2020, it was found to be in an enhanced flux...

We present the results of the DART imaging and CaII triplet (CaT) survey of the Fornax dwarf spheroidal galaxy (dSph) at ESO. We collected hundreds of low...

The observations were carried out between 2009 June 20 and August 20 in service mode with the ESO VLT instrument FORS2 at UT1 (Antu). FORS2 is a focal reducer...

The recent history of star formation in VII Zw 403 is analyzed taking into account the dynamics of the starburst blown superbubble and the restrictions that...

Context. Blue compact galaxies (BCG) are gas-rich, low-luminosity, low-metallicity systems that undergo a violent burst of star formation. These galaxies offer...
