    Resolving the AGN and Host Emission in the Mid-infrared using a Model-independent Spectral Decomposition
    We present results on the spectral decomposition of 118 Spitzer Infrared Spectrograph (IRS) spectra from local active galactic nuclei (AGNs) using a large set...

    Resonant Structure in the Disks of Spiral Galaxies, Using Phase Reversals in Streaming Motions from Two-dimensional Hα Fabry-Perot Spectroscopy
    In this Letter, we introduce a technique for finding resonance radii in a disk galaxy. We use a two-dimensional velocity field in Hα emission obtained with...

    Results of the digital co-addition of thirteen Schmidt films of the Virgo cluster of galaxies
    We have digitally co-added APM scans of 13 Kodak TechPan films of the SE region of the Virgo cluster of galaxies. The ~ 6.2degr x 6.2degr field of the R-band...

    Revisiting the transits of CoRoT-7b at a lower activity level
    The first super-Earth with measured radius discovered was CoRoT-7b and it has opened the new field of rocky exoplanet characterisation. To better understand...
