Description
Gravity is the key engine for the evolution of the universe and the formation of its main structures: galaxies, clusters of galaxies and filaments. Gravity is also an invaluable tool for exploring the universe through the relativistic effect of gravitational lensing. The gravitational potentials of clusters of galaxies turn these bodies into powerful cosmic telescopes which enhance the signal from high-redshift galaxies. In this paper we present a project to study such galaxies with the Gran Telescopio Canarias (GTC) and the instrument OSIRIS. We describe the gravitational lens effect, stressing the strong regime case in clusters of galaxies. Then we show an application of the numerical codes to study the cluster MS2137.3-2353. Finally, we discuss the use of the Large Millimeter Telescope (LMT) to find candidates for lensed galaxies at very high redshift.

    The European Low Frequency Survey. Observing the radio sky to understand the beginning of the Universe
    In this paper we present the European Low Frequency Survey (ELFS), a project that will enable the detection of primordial B-mode polarization by measuring the Galactic and extra-Galactic foregrounds in the 5- 120 GHz frequency window. Indeed, the main difficulty in measuring the Bmode polarization comes not just from its sheer faintness, but from

    Estimation of the hydrostatic-to-lensing mass bias from resolved cluster masses
    We present a study on the bias of hydrostatic masses with respect to lensing mass estimates for a sample of 53 clusters in a redshift range between z = 0.05 and 1.07. The M 500 mass for each cluster was inferred from X-ray and lensing data, without using a priori observable-mass scaling relations. Cluster masses of our reference analysis were

    IRAM 30-meter millimeter follow-up of deep OSIRIS-GTC optical surveys
    It is broadly accepted that CO is a reliable tracer of H2 in massive IR (L IR ≳ 10 9 L ⊙) galaxies, and that there are clear correlations between L IR and L' CO that are qualitatively independent of environment and even redshift. We present two tales on the search for 12CO emission from dusty star-forming galaxies in both field (Lockman Hole, z < 0
