    TeV gamma-ray observations of the Crab and MKN 501 during moonshine and twilight
    TeV gamma-ray signals from the Crab Nebula and Mkn 501 were detected with the HEGRA CT1 imaging Cerenkov telescope during periods when the moon was shining and...

    TeV pion bumps in the gamma-ray spectra of flaring blazars
    Context. Very high-energy (VHE, E > 100 GeV) observations of the blazar Mrk 501 with MAGIC in 2014 provided evidence for an unusual narrow spectral feature at...

    The "K-Correction" for Irradiated Emission Lines in LMXBs: Evidence for a Massive Neutron Star in X1822-371 (V691 CrA)
    We study the K-correction for the case of emission lines formed in the X-ray-illuminated atmosphere of a Roche lobe-filling star. We compute the K-correction as...

    The (galaxy-wide) IMF in giant elliptical galaxies: from top to bottom
    Recent evidence based independently on spectral line strengths and dynamical modelling point towards a non-universal stellar initial mass function (IMF)...

    The 1.5 meter solar telescope GREGOR
    The 1.5 m telescope GREGOR opens a new window to the understanding of solar small-scale magnetism. The first light instrumentation includes the Gregor Fabry...

    The 10-200 MU M spectral energy distribution of the prototype narrow-line X-ray galaxy NGC 7582
    We present the spectral energy distribution (SED) between 10 and 200 mu m obtained for the prototype narrow-line X-ray galaxy NGC 7582 with ISOPHOT, the...

    The 100 Myr Star Formation History of NGC 5471 from Cluster and Resolved Stellar Photometry
    We show that star formation in the giant H II region NGC 5471 has been ongoing during the past 100 Myr. Using Hubble Space Telescope/Wide-Field Planetary Camera...
