    Observations of the Hubble Deep Field with the Infrared Space Observatory - III. Source counts and P(D) analysis
    We present source counts at 6.7 and 15 μm from our maps of the Hubble Deep Field (HDF) region, reaching 38.6 muJy at 6.7 μm and 255 muJy at 15 mum. These are...

    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 recurrent M 31 transient XMMU J004215.8+411924 with Swift, Chandra, HST, and Einstein
    Context. The transient X-ray source XMMU J004215.8+411924 within M 31 was found to be in outburst again in the 2010 May 27 Chandra observation. We present...

    Observations of [OI]63-=μm line emission in main-sequence galaxies at z ∼ 1.5
    We present Herschel-PACS spectroscopy of four main-sequence star-forming galaxies at z ∼ 1.5. We detect [OI]63-=μm line emission in BzK-21000 at z = 1.5213, and...

    Observed versus simulated halo c-M<SUB>vir</SUB> relations
    The concentration - virial mass relation is a well-defined trend that reflects the formation of structure in an expanding universe. Numerical simulations reveal...

    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...

    OH megamasers, starburst and AGN activity in Markarian 231
    We present Multi-Element Radio-Linked Interferometer Network (MERLIN) observations of OH maser and radio continuum emission within a few hundred pc of the core...
