Description
Photometry and long-slit spectroscopy are presented for 14 S0 and spiral galaxies of the Fornax, Eridanus and Pegasus clusters and the NGC 7582 group. The age, metallicity and α/Fe enhancement of the stellar population in the centres and their gradients are obtained using stellar population models with variable element abundance ratios. Most of the sample bulges display solar α/Fe enhancement, no gradient in age, and a negative gradient of metallicity. One of the bulges, that of NGC 1292, is a pseudobulge and the properties of its stellar population are consistent with a slow build-up within a scenario of secular evolution.

    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
