Galaxies are found to obey scaling relations between a number of observables. These relations follow different trends at the low- and high-mass ends. The processes driving the curvature of scaling relations remain uncertain. In this Letter, we focus on the specific family of early-type galaxies, deriving the star formation histories of a complete

The LHC has been built to understand the dynamics at the origin of the breaking of the electroweak symmetry. Weakly coupled models with a fundamental Higgs boson have focused most of the attention of the experimental searches. We will discuss here how to reinterpret these searches in the context of strongly coupled models where the Higgs boson

Context. The old Galactic halo stars hold the fossil record of the interstellar medium chemical composition at the time of their formation. Most of the stars studied so far are relatively near to the Sun, this prompts the study of more distant stars, both to increase the size of the sample and to search for possible variations of abundance patterns

Deep optical photometry of the Fornax dSph in the B, V and I filters was obtained using the CTIO 4-m MOSAIC II camera over 9 nights in October 2008 and November 2009. Deep photometry for the outer fields was obtained as part of observing proposal 2008B-0397 (PI M. Mateo) supplemented by deep pointings covering the centre of Fornax as part of

Context. Paper I presents the magnetic structure, inferred for the photosphere and the chromosphere, of a filament that developed in active region (AR) NOAA 10781, observed on 2005 July 3 and July 5. Aims: In this paper we complement those results with the velocities retrieved from Doppler shifts measured at the chromosphere and the photosphere in
