    Insights into the emission of the blazar 1ES 1011+496 through unprecedented broadband observations during 2011 and 2012
    Context. 1ES 1011+496 (z = 0.212) was discovered in very high-energy (VHE, E> 100 GeV) γ rays with MAGIC in 2007. The absence of simultaneous data at lower...

    Insights into the High-energy γ-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
    We report on the γ-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) γ-ray...

    INSPIRE: INvestigating Stellar Population In RElics - VI. The low-mass end slope of the stellar initial mass function and chemical composition
    The INSPIRE project has built the largest sample of ultra-compact massive galaxies (UCMGs) at 0.1 < z < 0.4 and obtained their star formation histories (SFHs)...

    Integral field spectroscopy based Hα sizes of local luminous and ultraluminous infrared galaxies. A direct comparison with high-z massive star-forming galaxies
    Aims: We study the analogy between local luminous and ultraluminous infrared galaxies (U/LIRGs) and high-z massive star forming galaxies (SFGs) by comparing...

    Integral Field Spectroscopy of Blue Compact Dwarf Galaxies
    We present results of integral field optical spectroscopy of five luminous blue compact dwarf galaxies. The data were obtained using the fiber system INTEGRAL...
