    Discovery of Very High Energy Gamma Radiation from IC 443 with the MAGIC Telescope
    We report the detection of a new source of very high energy (VHE; Eγ>=100 GeV) γ-ray emission located close to the Galactic plane, MAGIC J0616+225, which is...

    Discovery of Very High Energy Gamma Rays from 1ES 1218+30.4
    The MAGIC collaboration has studied the high-frequency-peaked BL Lac object 1ES 1218+30.4, at a redshift z=0.182, using the MAGIC imaging air Cerenkov telescope...

    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 1ES 1011+496 at z = 0.212
    We report on the discovery of very high energy (VHE) γ-ray emission from the BL Lacertae object 1ES 1011+496. The observation was triggered by an optical...

    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...

    Disentangling the Galactic Halo with APOGEE. I. Chemical and Kinematical Investigation of Distinct Metal-poor Populations
    We find two chemically distinct populations separated relatively cleanly in the [Fe/H]–[Mg/Fe] plane, but also distinguished in other chemical planes, among...

    Disentangling the Galactic Halo with APOGEE. II. Chemical and Star Formation Histories for the Two Distinct Populations
    The formation processes that led to the current Galactic stellar halo are still under debate. Previous studies have provided evidence for different stellar...

    Disk Galaxies Are Self-similar: The Universality of the H I-to-Halo Mass Ratio for Isolated Disks
    Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the...

    Disk-integrated Intensity Pseudomodes Measured by SOHO/VIRGO
    The high-frequency spectrum above the acoustic cutoff frequency (νac) of the solar atmosphere has been observed in velocity measurements at low and high angular...
