In this paper, we use information from the light field to obtain a distribution map of the wavefront phase. This distribution is associated with changes in refractive index which are relevant in the propagation of light through a heterogeneous or turbulent medium. Through the measurement of the wavefront phase from a single shot, it is possible to

Understanding how different stellar populations evolve in different regions is a key to understand the evolution of galaxies. Traditionally the kinematics and stellar populations in galaxies have been obtained separately and unrelatedly, sometimes ignoring the other one. In this pilot study we simultaneously disentangle the stellar populations

J-PAS is a Spanish-Brazilian 8500 deg^2 Cosmological Survey which will be carried out from the Javalambre Observatory with a purpose-built, dedicated 2.5 m telescope and a 4.7 deg^2 camera with 1.2 Gpix. Starting in 2015, J-PAS will use 59 filters to measure high precision 0.003(1+z) photometric redshifts for 90M galaxies plus several million QSOs

We present the discovery of a new dwarf galaxy, Hydra II, found serendipitously within the data from the ongoing Survey of the Magellanic Stellar History conducted with the Dark Energy Camera on the Blanco 4 m Telescope. The new satellite is compact ({{r}h}=68 ± 11 pc) and faint ({{M}V}=-4.8 ± 0.3), but well within the realm of dwarf galaxies. The

The refinement of the brown dwarf binary fraction may contribute to the understanding of the substellar formation mechanisms. Peculiar brown dwarf spectra or discrepancy between optical and near-infrared spectral type classification of brown dwarfs may indicate unresolved brown dwarf binary systems. We obtained medium-resolution spectra of 22 brown

Context. Lightning flashes in Jupiter have been observed by spacecraft orbiting the planet, but so far, they have escaped optical detection from Earth. However, theoretical estimations suggest that these flashes may be detectable by a large telescope if they can be distinguished from the much more intense background of reflected sunlight from the
