Hi-GAL, the Herschel infrared Galactic Plane Survey: photometric maps and compact source catalogues. First data release for the inner Milky Way: +68° ≥ l ≥ -70°
Bernard, J. -P.; Martin, P. G.; Natoli, P. +61 more
Aims: We present the first public release of high-quality data products (DR1) from Hi-GAL, the Herschel infrared Galactic Plane Survey. Hi-GAL is the keystone of a suite of continuum Galactic plane surveys from the near-IR to the radio and covers five wavebands at 70, 160, 250, 350 and 500 µm, encompassing the peak of the spectral energ…
Kiloparsec-scale Dust Disks in High-redshift Luminous Submillimeter Galaxies
Smail, I.; Ivison, R. J.; Menten, K. M. +22 more
We present high-resolution (0.″16) 870 µm Atacama Large Millimeter/submillimeter Array (ALMA) imaging of 16 luminous ({L}{IR}∼ 4× {10}12 {L}⊙ ) submillimeter galaxies (SMGs) from the ALESS survey of the Extended Chandra Deep Field South. This dust imaging traces the dust-obscured star formation in these z∼ 2.…
The XXL Survey. I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
Smith, G. P.; Chiappetti, L.; Altieri, B. +89 more
Context. The quest for the cosmological parameters that describe our universe continues to motivate the scientific community to undertake very large survey initiatives across the electromagnetic spectrum. Over the past two decades, the Chandra and XMM-Newton observatories have supported numerous studies of X-ray-selected clusters of galaxies, acti…
On Galactic Density Modeling in the Presence of Dust Extinction
Bovy, Jo; Rix, Hans-Walter; Finkbeiner, Douglas P. +2 more
Inferences about the spatial density or phase-space structure of stellar populations in the Milky Way require a precise determination of the effective survey volume. The volume observed by surveys such as Gaia or near-infrared spectroscopic surveys, which have good coverage of the Galactic midplane region, is highly complex because of the abundant…
z ≳ 7 Galaxies with Red Spitzer/IRAC [3.6]-[4.5] Colors in the Full CANDELS Data Set: The Brightest-Known Galaxies at z ~ 7-9 and a Probable Spectroscopic Confirmation at z = 7.48
Oesch, P. A.; van Dokkum, P.; Bouwens, R. J. +9 more
We identify four unusually bright (H {}160,{AB} < 25.5) galaxies from Hubble Space Telescope (HST) and Spitzer CANDELS data with probable redshifts z ∼ 7-9. These identifications include the brightest-known galaxies to date at z ≳ 7.5. As Y-band observations are not available over the full CANDELS program to perform a standard Lyman-…
AIRUSE-LIFE+: a harmonized PM speciation and source apportionment in five southern European cities
Amato, Fulvio; Alastuey, Andrés; Karanasiou, Angeliki +21 more
The AIRUSE-LIFE+ project aims at characterizing similarities and heterogeneities in particulate matter (PM) sources and contributions in urban areas from southern Europe. Once the main PMx sources are identified, AIRUSE aims at developing and testing the efficiency of specific and non-specific measures to improve urban air quality. This article re…
Cosmological Constraints from Galaxy Clusters in the 2500 Square-degree SPT-SZ Survey
Gladders, M. D.; Schrabback, T.; Rest, A. +74 more
We present cosmological parameter constraints obtained from galaxy clusters identified by their Sunyaev-Zel’dovich effect signature in the 2500 square-degree South Pole Telescope Sunyaev Zel’dovich (SPT-SZ) survey. We consider the 377 cluster candidates identified at z\gt 0.25 with a detection significance greater than five, corresponding to the 9…
The Third Fermi GBM Gamma-Ray Burst Catalog: The First Six Years
Collazzi, Andrew C.; Preece, Robert D.; Kouveliotou, Chryssa +30 more
Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two γ-ray bursts (GRBs) every three days. Here, we present the third of a series of catalogs of GRBs detected by GBM, extending the second catalog by two more years through the middle of 2014 July. The resulting list includes 1405 t…
Planck 2015 results. XXVI. The Second Planck Catalogue of Compact Sources
Böhringer, H.; Kneissl, R.; Miville-Deschênes, M. -A. +240 more
The Second Planck Catalogue of Compact Sources is a list of discrete objects detected in single-frequency maps from the full duration of the Planck mission and supersedes previous versions. It consists of compact sources, both Galactic and extragalactic, detected over the entire sky. Compact sources detected in the lower frequency channels are ass…
Circumstellar debris and pollution at white dwarf stars
Farihi, J.
Circumstellar disks of planetary debris are now known or suspected to closely orbit hundreds of white dwarf stars. To date, both data and theory support disks that are entirely contained within the preceding giant stellar radii, and hence must have been produced during the white dwarf phase. This picture is strengthened by the signature of materia…
