    Detection of an intranight optical hard lag with colour variability in blazar PKS 0735+178
    Blazars are a highly variable subclass of active galactic nuclei that have been observed to vary significantly during a single night. This intranight...

    Detection of an ionized gas outflow in the extreme UV-luminous star-forming galaxy BOSS-EUVLG1 at z = 2.47
    BOSS-EUVLG1 is the most ultraviolet (UV) and Lyα luminous galaxy to be going through a very active starburst phase detected thus far in the Universe. It is...

    Detection of an X-Ray Jet in 3C 371 with Chandra
    We report the detection at X-rays of the radio/optical jet of 3C 371 from a short (10 ks) Chandra exposure in 2000 March. We also present a new MERLIN...

    Detection of Extended Optical Emission Associated with the Northern Radio Hot SPOT of 3C 390.3
    We present deep V, R, and I broadband CCD images of the northern radio lobe associated with the radio galaxy 3C 390.3. Spatially resolved emission coincident...

    Detection of Infalling Hydrogen in Transfer between the Interacting Galaxies NGC 5426 and NGC 5427
    Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot...

    Detection of persistent VHE gamma-ray emission from PKS 1510-089 by the MAGIC telescopes during low states between 2012 and 2017
    Context. PKS 1510-089 is a flat spectrum radio quasar strongly variable in the optical and GeV range. To date, very high-energy (VHE, > 100 GeV) emission has...

    Detection of satellite remnants in the Galactic halo with Gaia- III. Detection limits for ultrafaint dwarf galaxies
    We present a method to identify ultrafaint dwarf galaxies (UFDGs) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its...

    Detection of the 2175 Å Extinction Feature at z = 0.83
    We determine the extinction curve in the zl=0.83 lens galaxy of the gravitational lens SBS 0909+532 from the wavelength dependence of the flux ratio between the...

    Detection of the blazar S4 0954+65 at very-high-energy with the MAGIC telescopes during an exceptionally high optical state
    Aims: The very high energy (VHE ≳100 GeV) γ-ray MAGIC observations of the blazar S4 0954+65, were triggered by an exceptionally high flux state of emission in...
