    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves
    The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is...
  • Publication
    Hubble tensions: a historical statistical analysis
    Statistical analyses of measurements of the Hubble-Lemaître constant H 0 (163 measurements between 1976 and 2019) show that the statistical error bars...
  • Publication
    Interferometry of the Cosmic Microwave Background
    We describe the Very Small Array (VSA) and review the recent results on the angular power spectrum of the Cosmic Microwave Background (CMB) obtained in the Ka...
  • Publication
    Missing large-angle correlations versus even-odd point-parity imbalance in the cosmic microwave background
    Context. The existence of a maximum correlation angle (θ max ≳ 60°) in the two-point angular temperature correlations of cosmic microwave background (CMB)...
  • Publication
    New database for a sample of optically bright lensed quasars in the northern hemisphere
    In the framework of the Gravitational LENses and DArk MAtter (GLENDAMA) project, we present a database of nine gravitationally lensed quasars (GLQs) that have...

    Non-local contribution from small scales in galaxy-galaxy lensing: comparison of mitigation schemes
    Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 3 × 2pt, had to discard a lot of signal to noise...
