Modeling Rosetta's final descent
Blanco, Philip
Using Competitions to Engage the Public: Lessons Learnt from Rosetta
Bauer, M.; McCaughrean, M.; O'Flaherty, K. S. +9 more
The year 2014 was an historic and challenging time for the Rosetta mission. On 20 January the spacecraft awoke from a 957-day hibernation; by August, it had arrived at Comet 67P/Churyumov-Gerasimenko; and in November, the lander Philae was deployed to the comet's surface. These milestones were communicated by traditional outreach channels -- on we…
Assessing the contribution of centaur impacts to ice giant luminosities
Dodson-Robinson, Sarah E.
Voyager 2 observations revealed that Neptune's internal luminosity is an order of magnitude higher than that of Uranus. If the two planets have similar interior structures and cooling histories, Neptune's luminosity can only be explained by invoking some energy source beyond gravitational contraction. This paper investigates whether centaur impact…
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…
