We present very deep near-infrared imaging in the Js, H and Ks-bands of the HDF-S and the field around the z=0.83 cluster MS1054-03 with ISAAC on the VLT. For...

As targets of the fourth photometry campaign of the STEPHI network, the Delta Scuti stars BNCnc (HD73576) and BUCnc (HD73763) were simultaneously monitored...

DENIS is a project to survey the all-southern sky in three wavelength bands (Gunn-i 0.82 μm; J, 1.25 μm; and K_s, 2.15 μm) with limiting magnitudes 18.5, 16.5...

We report in this work on a project aimed at determining Lyα luminosity functions from z=3 to z=6. The project is based on the use of very deep photometry from...

WEAVE is the next-generation optical spectroscopy facility for the William Herschel Telescope and aims at spectroscopic follow-up of ground-based (LOFAR) and...

In principle, dark galaxies in the dwarf-galaxy mass range may be detectable through additional, small-scale image splitting of quasars that are already known...

Over the past two decades, enormous advances in the detection of exoplanets have taken place. Currently, we have discovered hundreds of Earth-sized planets...
