    An Integral View on Virgo and Field Dwarf Elliptical Galaxies: Late-Type Origin and Environmental Transformations
    Dwarf elliptical galaxies (dEs) are the most common galaxy class in dense environments. They are also a surprisingly inhomogenous class, which has made it...

    An Intensive HST, IUE, and Ground-Based Study of NGC 5548
    We present the first results of a combined HST/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order...

    An Intermediate-Mass Black Hole candidate in M51
    We undertake a study of M51 ULX-7, using archival data from XMM-Newton, Chandra and NuSTAR, and optical and radio data from HST and VLA. The source has a...

    An interpretation of the lightcurve of BL Lac.
    Extensive monitoring is now available for a good sample of the brighter quasars and BL Lacs. In some cases, lightcurves are well enough sampled to permit...

    An Inversion Technique to Derive Model Photospheres in Late-Type Stars from High-Resolution Spectroscopy: The Sun
    An inversion technique has been developed to recover LTE one-dimensional model photospheres for late-type stars from very high-resolution high signal-to-noise...

    An Investigation into the Radiation Damage of the Silicon Detectors of the H1-PLUG Calorimeter within the HERA environment
    The silicon detectors used in the H1-PLUG calorimeter have shown increasing aging effects during the '94 run period of the electron proton storage ring HERA...

    An ionised bubble before the epoch of recombination
    A proto-cluster of Lyα emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionising continuum photons. We find that...

    An Observational Study of Line-Profile Variable B-stars in Multiple Systems
    We present the results of an observational study of the pulsational behavior of the line-profile variable binary components of κ Sco, λ Sco and ɛ Lup. Our...
