    Discovery of a Dynamical Cold Point in the Heart of the Sagittarius dSph Galaxy with Observations from the APOGEE Project
    The dynamics of the core of the Sagittarius (Sgr) dwarf spheroidal (dSph) galaxy are explored using high-resolution (R ~ 22, 500), H-band, near-infrared spectra...

    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 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...
