    Discovery of true, likely and possible symbiotic stars in the dwarf spheroidal NGC 205
    In this paper we discuss the photometric and spectroscopic observations of newly discovered (symbiotic) systems in the dwarf spheroidal galaxy NGC 205. The...

    Discovery of two neighbouring satellites in the Carina constellation with MagLiteS
    We report the discovery of two ultra-faint satellites in the vicinity of the Large Magellanic Cloud (LMC) in data from the Magellanic Satellites Survey...

    Discovery of ultra-compact nuclear rings in three spiral galaxies
    Ring-shaped morphologies of nuclear star-forming regions within the central 40{-}200 pc of disk galaxies have been barely resolved so far in three composite Sy...

    Discovery of very high energy gamma-ray emission from the blazar 1ES 1727+502 with the MAGIC Telescopes
    Motivated by the prediction of a high TeV luminosity we investigated whether the blazar 1ES 1727+502 (z = 0.055) is emitting very high energy (VHE, E > 100 GeV)...

    Discovery of very high energy γ-ray emission from the blazar 1ES 0033+595 by the MAGIC telescopes
    The number of known very high energy (VHE) blazars is ˜50, which is very small in comparison to the number of blazars detected in other frequencies. This...

    Discovery of Very High Energy γ-Ray Emission from the Low-Frequency-peaked BL Lacertae Object BL Lacertae
    The MAGIC collaboration observed BL Lacertae for 22.2 hr during 2005 August to December and for 26 hr during 2006 July to September. The source is the...

    Discovery of Very High Energy γ-Rays from Markarian 180 Triggered by an Optical Outburst
    The high-frequency-peaked BL Lacertae object Markarian 180 (Mrk 180) was observed to have an optical outburst in 2006 March, triggering a Target of Opportunity...

    Discovery of VHE γ-ray emission from the BL Lacertae object B3 2247+381 with the MAGIC telescopes
    Aims: We study the non-thermal jet emission of the BL Lac object B3 2247+381 during a high optical state. Methods: The MAGIC telescopes observed the source...
