Probing for Evidence of Plumes on Europa with HST/STIS
Deustua, S. E.; Sparks, W. B.; Hand, K. P. +3 more
Roth et al. (2014a) reported evidence for plumes of water venting from a southern high latitude region on Europa: spectroscopic detection of off-limb line emission from the dissociation products of water. Here, we present Hubble Space Telescope direct images of Europa in the far-ultraviolet (FUV) as it transited the smooth face of Jupiter to measu…
Sulphur-bearing species in the coma of comet 67P/Churyumov-Gerasimenko
Altwegg, K.; Balsiger, H.; Berthelier, J. J. +15 more
Several sulphur-bearing species have already been observed in different families of comets. However, the knowledge on the minor sulphur species is still limited. The comet's sulphur inventory is closely linked to the pre-solar cloud and holds important clues to the degree of reprocessing of the material in the solar nebula and during comet accreti…
Evolution of the Dust Size Distribution of Comet 67P/Churyumov-Gerasimenko from 2.2 au to Perihelion
Jorda, L.; Lamy, P. L.; Bertaux, J. -L. +74 more
The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov-Gerasimenko, has been detecting individual dust particles of mass larger than 10-10 kg by means of the GIADA dust collector and the OSIRIS Wide Angle Camera and Narrow Angle Camera since 2014 August and will continue until 2016 September. Detections of single dust particles …
Planck 2015 results. XXVIII. The Planck Catalogue of Galactic cold clumps
Miville-Deschênes, M. -A.; Boulanger, F.; Bernard, J. -P. +220 more
We present the Planck Catalogue of Galactic Cold Clumps (PGCC), an all-sky catalogue of Galactic cold clump candidates detected by Planck. This catalogue is the full version of the Early Cold Core (ECC) catalogue, which was made available in 2011 with the Early Release Compact Source Catalogue (ERCSC) and which contained 915 high signal-to-noise s…
Planck 2015 results. XXI. The integrated Sachs-Wolfe effect
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +229 more
This paper presents a study of the integrated Sachs-Wolfe (ISW) effect from the Planck 2015 temperature and polarization data release. This secondary cosmic microwave background (CMB) anisotropy caused by the large-scale time-evolving gravitational potential is probed from different perspectives. The CMB is cross-correlated with different large-sc…
A combined transmission spectrum of the Earth-sized exoplanets TRAPPIST-1 b and c
Triaud, Amaury H. M. J.; Valenti, Jeff A.; Wakeford, Hannah R. +11 more
Three Earth-sized exoplanets were recently discovered close to the habitable zone of the nearby ultracool dwarf star TRAPPIST-1 (ref. 3). The nature of these planets has yet to be determined, as their masses remain unmeasured and no observational constraint is available for the planetary population surrounding ultracool dwarfs, of which the TRAPPI…
The VLT LEGA-C Spectroscopic Survey: The Physics of Galaxies at a Lookback Time of 7 Gyr
Wolf, C.; Brammer, G.; Rix, H. -W. +17 more
The Large Early Galaxy Census (LEGA-C) is a Public Spectroscopic Survey of ∼3200 K-band selected galaxies at redshifts z = 0.6 - 1.0 with stellar masses {M}*\gt {10}10\quad {M}⊙ , conducted with VIMOS on ESO’s Very Large Telescope. The survey is embedded in the COSMOS field (R.A. = 10h00; {decl}. = +2 {deg}). The 2…
The Swift GRB Host Galaxy Legacy Survey. II. Rest-frame Near-IR Luminosity Distribution and Evidence for a Near-solar Metallicity Threshold
Berger, E.; Chary, R.; Fynbo, J. P. U. +9 more
We present rest-frame near-IR (NIR) luminosities and stellar masses for a large and uniformly selected population of gamma-ray burst (GRB) host galaxies using deep Spitzer Space Telescope imaging of 119 targets from the Swift GRB Host Galaxy Legacy Survey spanning 0.03 < z < 6.3, and we determine the effects of galaxy evolution and chemical …
Improvement of cosmological neutrino mass bounds
Ho, Shirley; Mena, Olga; Gerbino, Martina +3 more
The most recent measurements of the temperature and low-multipole polarization anisotropies of the cosmic microwave background from the Planck satellite, when combined with galaxy clustering data from the Baryon Oscillation Spectroscopic Survey in the form of the full shape of the power spectrum, and with baryon acoustic oscillation measurements, …
Oblique Whistler-Mode Waves in the Earth's Inner Magnetosphere: Energy Distribution, Origins, and Role in Radiation Belt Dynamics
Agapitov, Oleksiy; Krasnoselskikh, Vladimir; Artemyev, Anton +3 more
In this paper we review recent spacecraft observations of oblique whistler-mode waves in the Earth's inner magnetosphere as well as the various consequences of the presence of such waves for electron scattering and acceleration. In particular, we survey the statistics of occurrences and intensity of oblique chorus waves in the region of the outer …
