    Discovery of a galactic wind in the central region of M100
    We report the discovery of a galactic wind in the central region of the galaxy M100. This result is based on a careful 2D spectroscopic study performed on...

    Discovery of a GeV Blazar Shining Through the Galactic Plane
    The Fermi Large Area Telescope (LAT) discovered a new gamma-ray source near the Galactic plane, Fermi J0109+6134, when it flared brightly in 2010 February. The...

    Discovery of a giant and luminous Lyα+C IV+He II nebula at z = 3.326 with extreme emission line ratios
    We present the discovery of HLock01-LAB, a luminous and large Lyα nebula at z = 3.326. Medium-band imaging and long-slit spectroscopic observations with the...

    Discovery of a Giant Stellar Tidal Stream Around The Disk Galaxy NGC 4013
    We report the discovery of a giant, looplike stellar structure around the edge-on spiral galaxy NGC 4013. This arcing feature extends 6' (~26 kpc in projected...

    Discovery of a high-z protocluster with tunable filters: the case of 6C0140+326 at z= 4.4
    We present the first results obtained using a tunable narrow-band filter in the search for high-z protoclusters. Using the recently commissioned red tunable...

    Discovery of a Lensed Ultrabright Submillimeter Galaxy at z = 2.0439
    We report an ultrabright lensed submillimeter galaxy (SMG) at z = 2.0439, WISE J132934.18+224327.3, identified as a result of a full-sky cross-correlation of...

    Discovery of a Lyα blob photo-ionised by a super-cluster of massive stars associated with a z = 3.49 galaxy
    Aims. We report the discovery and characterisation of a Lyman α (Lyα) blob close to a galaxy at redshift z = 3.49. We present the analysis we performed to check...

    Discovery of a Multiply Lensed Submillimeter Galaxy in Early HerMES Herschel/SPIRE Data
    We report the discovery of a bright (f(250 μm)>400 mJy), multiply lensed submillimeter galaxy HERMES J105751.1+573027 in Herschel/SPIRE Science Demonstration...

    Discovery of a red ultra-diffuse galaxy in a nearby void based on its globular cluster luminosity function
    Distance determinations of extremely low-surface-brightness galaxies are expensive in terms of spectroscopic time. Because of this, their distances are often...
