Spectroscopic Confirmation of A Radio - Selected Galaxy
We report the discovery of a galaxy overdensity at z = 1.11 associated with the z = 1.110 high-redshift radio galaxy MG 0442+0202. The group, CL 0442+0202, was found in a near-infrared survey of z > 1 radio galaxies undertaken to identify spatiallycoincident regions with a high density of objects red in I − K ′ color, typical of z > 1 elliptical galaxies. Spectroscopic observations from the Kec...
متن کاملA Spectroscopic Confirmation of the Boötes Ii Dwarf Spheroidal
We present a new suite of photometric and spectroscopic data for the faint Boötes II dwarf spheroidal galaxy candidate. Our deep photometry, obtained with the INT/WFC, suggests a distance of 46 kpc and a small half-light radius of 4.0 (56 pc), consistent with previous estimates. Follow-up spectroscopy obtained with the Gemini/GMOS instrument yielded radial velocities and metallicities. While th...
متن کاملSpectroscopic confirmation of clusters from the ESO imaging survey
We measure redshifts for 67 galaxies in the field of six cluster candidates from the ESO Imaging Survey (EIS). The cluster candidates are selected in the EIS patches C and D among those with estimated mean redshifts 0.5 ≤ z ≤ 0.7. The observations were made with EFOSC2 at the 3.6m ESO telescope. In the six candidate cluster fields, we identify 19 possible sets of 2 to 7 galaxies in redshift spa...
متن کاملUVES observations of the Canis Major overdensity ⋆
We present the first detailed chemical abundances for three giant stars which are candidate members of the Canis Major over-density, obtained by using FLAMES-UVES at VLT. The stars, in the background of the open cluster NGC 2477, have radial velocities compatible with a membership to this structure. However, due to Galactic disc contamination, radial velocity by itself is unable to firmly estab...
متن کاملSpectroscopic Confirmation of an Extreme Starburst at Redshift 4.547*
We report the spectroscopic confirmation of a sub-mm galaxy (SMG) at z = 4.547 with an estimated LIR = 0.5−2.0×10 L⊙. The spectra, mid-IR, and X-ray properties indicate the bolometric luminosity is dominated by star formation at a rate of > 1000M⊙yr . Multiple, spatially separated components are visible in the Ly-Alpha line with an observed velocity difference of up to 380 km/sec and the object...
