The clustering of the SDSS DR7 main Galaxy sample - I. A 4 per cent distance measure at z = 0.15
Howlett, Cullan; Manera, Marc; Ross, Ashley J. +3 more
We create a sample of spectroscopically identified galaxies with z < 0.2 from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7), covering 6813 deg2. Galaxies are chosen to sample the highest mass haloes, with an effective bias of 1.5, allowing us to construct 1000 mock galaxy catalogues (described in Paper II), which we use to…
Fermi Large Area Telescope Third Source Catalog
Troja, E.; Caraveo, P. A.; Mirabal, N. +169 more
We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in the 100 MeV-300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma-ray Space Telescope mission, it is the deepest yet in this energy range. Relative to the Second Fermi LAT catalog, the 3FGL catalog incorporates twice as much data, as wel…
The 2014 ALMA Long Baseline Campaign: First Results from High Angular Resolution Observations toward the HL Tau Region
Kneissl, R.; Andreani, P.; Hill, T. +82 more
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region. The continuum images at wavelengths of 2.9, 1.3, and 0.87 mm have unprecedented angular resolutions of 0.″ 075 (10 AU) to 0.″ 025 (3.5 AU), revealing an astonishing le…
UV Luminosity Functions at Redshifts z ∼ 4 to z ∼ 10: 10,000 Galaxies from HST Legacy Fields
Trenti, M.; Oesch, P. A.; Bouwens, R. J. +11 more
The remarkable Hubble Space Telescope (HST) data sets from the CANDELS, HUDF09, HUDF12, ERS, and BoRG/HIPPIES programs have allowed us to map the evolution of the rest-frame UV luminosity function (LF) from z∼ 10 to z∼ 4. We develop new color criteria that more optimally utilize the full wavelength coverage from the optical, near-IR, and mid-IR ob…
Joint Analysis of BICEP2/Keck Array and Planck Data
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +277 more
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg2 patch of sky centered on RA 0 h, Dec. -57.5 ° . The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polariz…
Baryon acoustic oscillations in the Lyα forest of BOSS DR11 quasars
Pâris, Isabelle; Petitjean, Patrick; Aubourg, Éric +35 more
We report a detection of the baryon acousticoscillation (BAO) feature in the flux-correlation function of the Lyα forest of high-redshift quasars with a statistical significance of five standard deviations. The study uses 137 562 quasars in the redshift range 2.1 ≤ z ≤ 3.5 from the data release 11 (DR11) of the Baryon Oscillation Spectroscopic Sur…
Cosmic Reionization and Early Star-forming Galaxies: A Joint Analysis of New Constraints from Planck and the Hubble Space Telescope
Ellis, Richard S.; Robertson, Brant E.; Dunlop, James S. +1 more
We discuss new constraints on the epoch of cosmic reionization and test the assumption that most of the ionizing photons responsible arose from high-redshift star-forming galaxies. Good progress has been made in charting the end of reionization through spectroscopic studies of z ≃ 6-8 QSOs, gamma-ray bursts, and galaxies expected to host Lyα emiss…
The Herschel view of the dominant mode of galaxy growth from z = 4 to the present day
Magnelli, B.; Aussel, H.; Daddi, E. +20 more
We present an analysis of the deepest Herschel images in four major extragalactic fields GOODS-North, GOODS-South, UDS, and COSMOS obtained within the GOODS-Herschel and CANDELS-Herschel key programs. The star formation picture provided by a total of 10 497 individual far-infrared detections is supplemented by the stacking analysis of a mass compl…
Cosmological implications of baryon acoustic oscillation measurements
Pâris, Isabelle; Petitjean, Patrick; Aubourg, Éric +93 more
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave background (CMB) data and a recent reanalysis of Type Ia supernova (SN) data. In particular, we take advantage of high-precision BAO measurements from galaxy clustering and th…
The Evolution of the Galaxy Rest-frame Ultraviolet Luminosity Function over the First Two Billion Years
Papovich, Casey; Finkelstein, Steven L.; Castellano, Marco +26 more
We present a robust measurement and analysis of the rest-frame ultraviolet (UV) luminosity functions at z = 4-8. We use deep Hubble Space Telescope imaging over the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey/GOODS fields, the Hubble Ultra Deep Field, and the Hubble Frontier Field deep parallel observations near the Abell 2744 a…
