Cosmic discordance: are Planck CMB and CFHTLenS weak lensing measurements out of tune?
Jain, Bhuvnesh; Zuntz, Joe; Bridle, Sarah +2 more
We examine the level of agreement between low-redshift weak lensing data and the cosmic microwave background using measurements from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) and Planck+Wilkinson Microwave Anisotropy Probe (WMAP) polarization. We perform an independent analysis of the CFHTLenS six bin tomography results of Heyma…
The Most Luminous Galaxies Discovered by WISE
Tsai, Chao-Wei; Juneau, Stéphanie; Gelino, Christopher R. +25 more
We present 20 Wide-field Infrared Survey Explorer (WISE)-selected galaxies with bolometric luminosities Lbol > 1014 L⊙, including five with infrared luminosities LIR ≡ L(rest 8-1000 µm) > 1014 L⊙. These “extremely luminous infrared galaxies,” or ELIRGs, were d…
A Stubbornly Large Mass of Cold Dust in the Ejecta of Supernova 1987A
Ivison, R. J.; van Loon, J. Th.; Lundqvist, P. +33 more
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 µm data and improved imaging quality at 100 and 160 µm compared to previous observations in 2010. Our Herschel spectra show only weak CO line emission, and provide an upper li…
Strong coronal channelling and interplanetary evolution of a solar storm up to Earth and Mars
Dumbović, Mateja; Temmer, Manuela; Vršnak, Bojan +15 more
The severe geomagnetic effects of solar storms or coronal mass ejections (CMEs) are to a large degree determined by their propagation direction with respect to Earth. There is a lack of understanding of the processes that determine their non-radial propagation. Here we present a synthesis of data from seven different space missions of a fast CME, …
Properties of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies
Maraschi, L.; Tagliaferri, G.; Lähteenmäki, A. +27 more
We have conducted a multiwavelength survey of 42 radio loud narrow-1ine Seyfert 1 galaxies (RLNLS1s), selected by searching among all the known sources of this type and omitting those with steep radio spectra. We analyse data from radio frequencies to X-rays, and supplement these with information available from online catalogues and the literature…
Dissipation and heating in solar wind turbulence: from the macro to the micro and back again

New redshift z ≃ 9 galaxies in the Hubble Frontier Fields: implications for early evolution of the UV luminosity density
McLure, R. J.; Dunlop, J. S.; McLeod, D. J. +3 more
We present the results of a new search for galaxies at redshift z ≃ 9 in the first two Hubble Frontier Fields with completed HST WFC3/IR and ACS imaging. To ensure robust photometric redshift solutions, and to minimize incompleteness, we confine our search to objects with H160 < 28.6 (AB mag), consider only image regions with an rms …
T-PHOT: A new code for PSF-matched, prior-based, multiwavelength extragalactic deconfusion photometry
Elbaz, D.; Shu, X.; Ferguson, H. C. +19 more
Context. The advent of deep multiwavelength extragalactic surveys has led to the necessity for advanced and fast methods for photometric analysis. In fact, codes which allow analyses of the same regions of the sky observed at different wavelengths and resolutions are becoming essential to thoroughly exploit current and future data. In this context…
Photohadronic origin of γ -ray BL Lac emission: implications for IceCube neutrinos
Padovani, P.; Resconi, E.; Mastichiadis, A. +2 more
The recent IceCube discovery of 0.1-1 PeV neutrinos of astrophysical origin opens up a new era for high-energy astrophysics. Although there are various astrophysical candidate sources, a firm association of the detected neutrinos with one (or more) of them is still lacking. A recent analysis of plausible astrophysical counterparts within the error…
New Constraints on the Faint End of the UV Luminosity Function at z ~ 7-8 Using the Gravitational Lensing of the Hubble Frontier Fields Cluster A2744
Richard, Johan; Schaerer, Daniel; Kneib, Jean-Paul +8 more
Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond the limits of blank field surveys. Using the complete Hubble Space Telescope observations of the first HFF cluster A2744, we report the detection of 50 galaxy candidates at…
