Description
We have completed a survey of early-type galaxies in a region covering 700 sq. degrees with cz<7000km/s. We find no early-type galaxies with MB > -20 that satisfy our isolation criteria. The sample galaxies obey the Mg-sigma relation but have a higher frequency of [OII] and [OIII] emission than found in the Fornax cluster. They appear to be younger than the ellipticals in the Fornax cluster having a spread in luminosity weighted ages similar to lenticular galaxies. This work was funded by the PPARC rolling grant: ``Extragalactic Astronomy and Cosmology in Durham 2000-2004'' PPA/G/O/1999/00604.

    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
