    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: Improving the efficiency of weak lensing shear bias calibration. Pixel noise cancellation and the response method on trial
    To obtain an accurate cosmological inference from upcoming weak lensing surveys such as the one conducted by Euclid, the shear measurement requires calibration...

    Exploring the correlation between dark matter, intracluster light, and globular cluster distribution in SMACS0723
    We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass...

    Extragalactic science with EMIR-GTC
    EMIR is a wide-field, near-IR spectrograph currently under development for the Nasmyth focus of the Spanish 10.4m GTC at Canary Islands. EMIR will provide...

    Far-infrared constraints on the contamination by dust-obscured galaxies of high-z dropout searches
    The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared...

    Fast Multipole Method for Gravitational Lensing: Application to High-magnification Quasar Microlensing
    We introduce the use of the fast multipole method (FMM) to speed up gravitational lensing ray tracing calculations. The method allows very fast calculation of...

    First Assessment of the Binary Lens OGLE-2015-BLG-0232
    We present an analysis of the microlensing event OGLE-2015-BLG-0232. This event is challenging to characterize for two reasons. First, the light curve is not...

    First black hole mass estimation for the quadruple lensed system WGD2038-4008
    Context. The quadruple lensed system WGD2038-4008 (z s = 0.777 ± 0.001) has recently been discovered with the help of new techniques and observations. Black...

    First Direct Evidence for Keplerian Rotation in Quasar Inner Broad-line Regions
    We introduce a novel method to derive rotation curves with light-day spatial resolution of the inner regions of lensed quasars. We aim to probe the kinematics...
