    Flat-spectrum symmetric objects with ~1kpc sizes - I. The candidates
    In order to understand the origin and evolution of radio galaxies, searches for the youngest such sources have been conducted. Compact symmetric objects (CSOs)...

    Fluctuations of K-band galaxy counts
    We measure the variance in the distribution of off-plane (|b|>20o ) galaxies with m_K

    Follow-up observations at 16 and 33GHz of extragalactic sources from WMAP 3-yr data: I - Spectral properties
    We present follow-up observations of 97 point sources from the Wilkinson Microwave Anisotropy Probe (WMAP) 3-yr data, contained within the New Extragalactic...

    Follow-up observations at 16 and 33GHz of extragalactic sources from WMAP 3-yr data: II - Flux density variability
    Using the Arcminute Microkelvin Imager (AMI) at 16GHz and the Very Small Array (VSA) at 33GHz to make follow-up observations of sources in the New Extragalactic...

    Footprints of the early Universe in the SFHs of dwarf galaxies
    We present the star formation histories (SFHs) as a function of galactocentric radius of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix. Our...

    Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters
    Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first...

    Formation and evolution of dwarf early-type galaxies in the Virgo cluster. II. Kinematic scaling relations
    We place our sample of 18 Virgo dwarf early-type galaxies (dEs) on the (V - K)e-velocity dispersion, Faber-Jackson, and fundamental plane (FP) scaling relations...

    Formation and evolution of S0 galaxies: a SAURON case study of NGC 7332
    We present SAURON integral-field observations of the S0 galaxy NGC 7332. Existing broad-band ground-based and Hubble Space Telescope (HST) photometry reveals a...
