A Measurement of Secondary Cosmic Microwave Background Anisotropies from the 2500 Square-degree SPT-SZ Survey
DOI: 10.1088/0004-637X/799/2/177 Bibcode: 2015ApJ...799..177G

Bleem, L. E.; Stark, A. A.; George, E. M. +45 more

We present measurements of secondary cosmic microwave background (CMB) anisotropies and cosmic infrared background (CIB) fluctuations using data from the South Pole Telescope (SPT) covering the complete 2540 deg2 SPT-SZ survey area. Data in the three SPT-SZ frequency bands centered at 95, 150, and 220 GHz, are used to produce six angula…

The formation of massive, compact galaxies at z = 2 in the Illustris simulation
DOI: 10.1093/mnras/stv303 Bibcode: 2015MNRAS.449..361W

van Dokkum, Pieter; Kriek, Mariska; Wellons, Sarah +13 more

Massive, quiescent galaxies at high redshift have been found to be considerably more compact than galaxies of similar mass in the local universe. How these compact galaxies formed has yet to be determined, though several progenitor populations have been proposed. Here we investigate the formation processes and quantify the assembly histories of su…

Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate
DOI: 10.1088/0004-637X/800/1/40 Bibcode: 2015ApJ...800...40I

Menten, K. M.; Falgarone, E.; Godard, B. +19 more

In diffuse interstellar clouds the chemistry that leads to the formation of the oxygen-bearing ions OH+, H2O+, and H3O+ begins with the ionization of atomic hydrogen by cosmic rays, and continues through subsequent hydrogen abstraction reactions involving H2. Given these reaction pa…

A Spectroscopic Redshift Measurement for a Luminous Lyman Break Galaxy at z = 7.730 Using Keck/MOSFIRE
DOI: 10.1088/2041-8205/804/2/L30 Bibcode: 2015ApJ...804L..30O

Oesch, P. A.; Bouwens, R. J.; Illingworth, G. D. +9 more

We present a spectroscopic redshift measurement of a very bright Lyman break galaxy at z=7.7302+/- 0.0006 using the Keck/Multi-Object Spectrometer for Infra-Red Exploration. The source was pre-selected photometrically in the EGS field as a robust z ∼ 8 candidate with H = 25.0 mag based on optical non-detections and a very red Spitzer/IRAC [3.6]-[4…

The Grism Lens-Amplified Survey from Space (GLASS). I. Survey Overview and First Data Release
DOI: 10.1088/0004-637X/812/2/114 Bibcode: 2015ApJ...812..114T

Malkan, M. A.; Poggianti, B.; Vulcani, B. +19 more

We give an overview of the Grism Lens Amplified Survey from Space (GLASS), a large Hubble Space Telescope program aimed at obtaining grism spectroscopy of the fields of 10 massive clusters of galaxies at redshift z = 0.308-0.686, including the Hubble Frontier Fields (HFF). The Wide Field Camera 3 (WFC3) yields near-infrared spectra of the cluster …

The SCUBA-2 Cosmology Legacy Survey: ALMA Resolves the Rest-frame Far-infrared Emission of Sub-millimeter Galaxies
DOI: 10.1088/0004-637X/799/1/81 Bibcode: 2015ApJ...799...81S

Thomson, A. P.; Ivison, R. J.; Scott, D. +26 more

We present high-resolution (0.''3) Atacama Large Millimeter Array 870 µm imaging of 52 sub-millimeter galaxies (SMGs) in the Ultra Deep Survey field to investigate the size and morphology of the sub-millimeter (sub-mm) emission on 2-10 kpc scales. We derive a median intrinsic angular size of FWHM = 0.''30 ± 0.''04 for the 23 SMGs in the samp…

The Herschel Dwarf Galaxy Survey. I. Properties of the low-metallicity ISM from PACS spectroscopy
DOI: 10.1051/0004-6361/201425207 Bibcode: 2015A&A...578A..53C

Cooray, A.; Lebouteiller, V.; Madden, S. C. +17 more

Context. The far-infrared (FIR) lines are important tracers of the cooling and physical conditions of the interstellar medium (ISM) and are rapidly becoming workhorse diagnostics for galaxies throughout the universe. There are clear indications of a different behavior of these lines at low metallicity that needs to be explored.
Aims: Our goal…

High-mass X-ray binaries in the Milky Way. A closer look with INTEGRAL
DOI: 10.1007/s00159-015-0082-6 Bibcode: 2015A&ARv..23....2W

Tsygankov, Sergey S.; Lutovinov, Alexander A.; Walter, Roland +1 more

High-mass X-ray binaries are fundamental in the study of stellar evolution, nucleosynthesis, structure and evolution of galaxies and accretion processes. Hard X-rays observations by INTEGRAL and Swift have broadened significantly our understanding in particular for the super-giant systems in the Milky Way, whose number has increased by almost a fa…

GOODS-Herschel: Star Formation, Dust Attenuation, and the FIR-radio Correlation on the Main Sequence of Star-forming Galaxies up to z ≃4
DOI: 10.1088/0004-637X/807/2/141 Bibcode: 2015ApJ...807..141P

Aussel, H.; Daddi, E.; Elbaz, D. +25 more

We use deep panchromatic data sets in the GOODS-N field, from GALEX to the deepest Herschel far-infrared (FIR) and VLA radio continuum imaging, to explore the evolution of star-formation activity and dust attenuation properties of star-forming galaxies to z ≃ 4, using mass-complete samples. Our main results can be summarized as follows: (i) the sl…

Context. The Rosetta mission of the European Space Agency has been orbiting the comet 67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A large complement of scientific experiments designed to complete the most detailed study of a comet ever attempted are onboard Rosetta.
Aims: We present results for the photom…
