    Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction
    We present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are...

    Dark Energy Survey Year 3 Results: Galaxy mock catalogs for BAO analysis
    The calibration and validation of scientific analysis in simulations is a fundamental tool to ensure unbiased and robust results in observational cosmology. In...

    Dark Energy Survey Year 3 results: marginalization over redshift distribution uncertainties using ranking of discrete realizations
    Cosmological information from weak lensing surveys is maximized by sorting source galaxies into tomographic redshift subsamples. Any uncertainties on these...

    Dark energy survey year 3 results: weak lensing shape catalogue
    We present and characterize the galaxy shape catalogue from the first 3 yr of Dark Energy Survey (DES) observations, over an effective area of 4143 deg 2 of the...

    Dark matter annihilation and the Galactic Centre Excess
    We compare the surface brightness profile and morphology of the Galactic Centre Excess (GCE) identified in wide-angle γ-ray maps from the Fermi-Large Area...

    Dark Matter Decay and Annihilation in the Local Universe: Clues from Fermi
    We present all-sky simulated Fermi maps of γ-rays from dark matter (DM) decay and annihilation in the local universe. The DM distribution is obtained from a...

    Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology
    We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo mass and redshift in the...

    Data Reduction Pipeline for EMIR, the Near-IR Multi-Object Spectrograph for GTC
    EMIR (Balcells et al. 2000) is a near-infrared wide-field camera and multi-object spectrograph being built for the GTC. The Data Reduction Pipeline (DRP) will...

    Data treatment towards the ELT age. The ESPRESSO case
    Several ambitious scientific projects are currently pushing the limits of astrophysical spectroscopy, in terms of wavelength accuracy and long-term stability...
