    Detection of Very High Energy γ-ray Emission from the Perseus Cluster Head-Tail Galaxy IC 310 by the MAGIC Telescopes
    We report on the detection with the MAGIC telescopes of very high energy (VHE) γ-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster...

    Detection of very-high energy γ-ray emission from NGC 1275 by the MAGIC telescopes
    We report on the detection of very-high energy (VHE, E > 100 GeV) γ-ray emission from NGC 1275, the central radio galaxy of the Perseus cluster of galaxies. The...

    Detection of young (≤20 Myr) stellar populations in apparently quenched low-mass galaxies using red spectral line indices
    We report on the detection of a small contribution (around and below 1 per cent in mass) from young stellar components with ages ≤20 Myr in low-mass galaxies...

    Determination of the pattern speed in the grand design spiral galaxy NGC 4321.
    Measurement of pattern speeds has been an observational imperative in the last years since a clear determination of the corotation resonance radius will give...

    Determination of the properties of the central engine in microlensed QSOs
    We study a recently observed gravitational microlensing peak in the V-band light curve of Q2237+0305A using a relatively simple physical model, but one that is...

    Determining the fraction of reddened quasars in COSMOS with multiple selection techniques from X-ray to radio wavelengths
    The sub-population of quasars reddened by intrinsic or intervening clouds of dust are known to be underrepresented in optical quasar surveys. By defining a...

    Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation
    We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in...

    Diagnostic diagrams of H 0 regions in the Local Group
    We have studied here for the first time the use of the log(H 0/[N 0]), log (H 0/[S 0]) diagnostic diagram for determining the metallicities and ionization...

    Differences and similarities of stellar populations in LAEs and LBGs at z ∼ 3.4-6.8
    Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) represent the most common groups of star-forming galaxies at high z, and the differences between...
