An Integral View of Balmer-dominated Shocks in Supernova Remnants
We present integral-field spectroscopic observations with the VIMOS-IFU at the VLT of fast (2000-3000 kms-1) Balmer-dominated shocks surrounding the...
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...
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...
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...
