    Euclid: Constraining dark energy coupled to electromagnetism using astrophysical and laboratory data
    In physically realistic, scalar-field-based dynamical dark energy models (including, e.g., quintessence), one naturally expects the scalar field to couple to...

    Euclid: Cosmology forecasts from the void-galaxy cross-correlation function with reconstruction
    We have investigated the cosmological constraints that can be expected from measurement of the cross-correlation of galaxies with cosmic voids identified in the...

    Euclid: Forecasts from redshift-space distortions and the Alcock-Paczynski test with cosmic voids
    Euclid is poised to survey galaxies across a cosmological volume of unprecedented size, providing observations of more than a billion objects distributed over a...

    Euclid: Forecasts from the void-lensing cross-correlation
    The Euclid space telescope will survey a large dataset of cosmic voids traced by dense samples of galaxies. In this work we estimate its expected performance...

    Euclid: Testing the Copernican principle with next-generation surveys
    Context. The Copernican principle, the notion that we are not at a special location in the Universe, is one of the cornerstones of modern cosmology. Its...

    Extracting cosmological information from the angular power spectrum of the 2MASS Photometric Redshift catalogue
    Using the almost all-sky 2MASS Photometric Redshift catalogue (2MPZ) we perform for the first time a tomographic analysis of galaxy angular clustering in the...

    First Cosmology Results using Supernovae Ia from the Dark Energy Survey: Survey Overview, Performance, and Supernova Spectroscopy
    We present details on the observing strategy, data-processing techniques, and spectroscopic targeting algorithms for the first three years of operation for the...

    First results from the Very Small Array - IV. Cosmological parameter estimation
    We investigate the constraints on basic cosmological parameters set by the first compact-configuration observations of the Very Small Array (VSA), and other...
