Mapping the low surface brightness (μ >28 mag arcsec^{-2}) structures of the galaxies opens the possibility of testing our current ΛCDM galaxy formation model. At these surface brightness values the accretion history of the galaxies should clearly reveal. We present here two undergoing projects conducted at the IAC whose aim is to explore the

GLORIA, funded under the auspices of the EU FP7 program in 2012--14, is a collaborative web--2.0 project based on a network of 18 robotic telescopes, which has become the first free-access network opened to the world for public outreach and specially for e-Science projects. On-line (solar and night) observations (experiments) as well as batch-mode

We present a new code for fitting radial velocities of stellar binaries and exoplanets using an Adaptive Simulated Annealing (ASA) global minimisation method. ASA belongs to the family of Monte Carlo methods and its main advantages are that it only needs evaluations of the objective function, it does not rely on derivatives, and the parameters

The amount of energy coming into the Earth's climate system is the combination of two parameters: solar constant, and Earth's albedo (or reflectance). Our main goal in this work is to record an absolutely-calibrated global albedo time series. The albedo can be determined by alternative observations of the bright and dark sides of the Moon. The

COrE+ has been proposed to ESA as a medium-class mission for investigating, within the framework of the ESA Cosmic Vision program, a set of important scientific questions that require high sensitivity, full-sky observations of the sky emission at wavelengths ranging from millimeter-wave to the far-infrared. Its main scientific objective is to

Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expect them to share the same chemical composition. Most of the stellar aggregates are disrupted while orbiting the Galaxy and most of the dynamic information is lost, thus the only possibility of
