    Observations of the Hubble Deep Field with the Infrared Space Observatory - IV. Association of sources with Hubble Deep Field galaxies
    We discuss the identification of sources detected by the Infrared Space Observatory (ISO) at 6.7 and 15 μ in the Hubble Deep Field (HDF) region. We...

    Observations of the Hubble Deep Field with the Infrared Space Observatory - V. Spectral energy distributions, starburst models and star formation history
    We have modelled the spectral energy distributions of the 13 Hubble Deep Field (HDF) galaxies reliably detected by the Infrared Space Observatory (ISO). For two...

    Observations of the microwave background on a scale of 8 deg. I - The observing system
    A sensitive observing system for observing the cosmic microwave background on an angular scale of 8 deg is described. This angular scale is appropriate for...

    Observing the Dark Matter Density Profile of Isolated Galaxies
    Using the Sloan Digital Sky Survey (SDSS), we probe the halo mass distribution by studying the velocities of satellites orbiting isolated galaxies. In a...

    On an analytical framework for voids: their abundances, density profiles and local mass functions
    We present a general analytical procedure for computing the number density of voids with radius above a given value within the context of gravitational...
  • Publication
    On the application of the spherical infall model to real (anisotropic and/or non-isolated) mass concentrations
    We have studied analytically the mean pull on shells of real (anisotropic and/or non-isolated) mass concentrations. Using a non-linear scheme, the radial...

    On the Environmental Dependence of the Cluster Galaxy Assembly Timescale
    We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in eight clusters over a range of richness and morphology. Spectra...

    On the Eulerian Approach to the Evolution of Large-Scale Structures
    Within the classical Eulerian theory of gravitational instability, and in an Omega = 1 universe, we introduce a method for obtaining iterative solutions for the...

    On the influence of resonant scattering on cosmic microwave background polarization anisotropies
    We implement the theory of resonant scattering in the context of cosmic microwave background (CMB) polarization anisotropies. We compute the changes in the E...
