The COSMOS2015 Catalog: Exploring the 1 < z < 6 Universe with Half a Million Galaxies
Aussel, H.; Le Floc'h, E.; Sanders, D. B. +34 more
We present the COSMOS201524 catalog, which contains precise photometric redshifts and stellar masses for more than half a million objects over the 2deg2 COSMOS field. Including new {{YJHK}}{{s}} images from the UltraVISTA-DR2 survey, Y-band images from Subaru/Hyper-Suprime-Cam, and infrared data from the Spitzer La…
A unified multiwavelength model of galaxy formation
Baugh, Carlton M.; Lagos, Claudia D. P.; Cole, Shaun +7 more
We present a new version of the GALFORM semi-analytical model of galaxy formation. This brings together several previous developments of GALFORM into a single unified model, including a different initial mass function (IMF) in quiescent star formation and in starbursts, feedback from active galactic nuclei suppressing gas cooling in massive haloes…
The SFR-M* Relation and Empirical Star-Formation Histories from ZFOURGE* at 0.5 < z < 4
Papovich, Casey; Dickinson, Mark; Inami, Hanae +19 more
We explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M*). Using data from the FourStar Galaxy Evolution Survey (ZFOURGE) in combination with far-IR imaging from the Spitzer and Herschel observatories we measure the SFR-M* relation at 0.5 < z <…
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…
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…
The FourStar Galaxy Evolution Survey (ZFOURGE): Ultraviolet to Far-infrared Catalogs, Medium-bandwidth Photometric Redshifts with Improved Accuracy, Stellar Masses, and Confirmation of Quiescent Galaxies to z ∼ 3.5
Papovich, Casey; Kelson, Daniel D.; Kacprzak, Glenn G. +26 more
The FourStar galaxy evolution survey (ZFOURGE) is a 45 night legacy program with the FourStar near-infrared camera on Magellan and one of the most sensitive surveys to date. ZFOURGE covers a total of 400 arcmin2 in cosmic fields CDFS, COSMOS and UDS, overlapping CANDELS. We present photometric catalogs comprising >70,000 galaxies, se…
The Herschel Orion Protostar Survey: Spectral Energy Distributions and Fits Using a Grid of Protostellar Models
Manoj, P.; Megeath, S. T.; Watson, D. M. +12 more
We present key results from the Herschel Orion Protostar Survey: spectral energy distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in the Orion molecular clouds. This is the largest sample of protostars studied in a single, nearby star formation complex. With near-infrared photometry from 2MASS, mid- and f…
The Link between Turbulence, Magnetic Fields, Filaments, and Star Formation in the Central Molecular Zone Cloud G0.253+0.016
Testi, L.; Federrath, C.; Bally, J. +8 more
Star formation is primarily controlled by the interplay between gravity, turbulence, and magnetic fields. However, the turbulence and magnetic fields in molecular clouds near the Galactic center may differ substantially compared to spiral-arm clouds. Here we determine the physical parameters of the central molecular zone (CMZ) cloud G0.253+0.016, …
The Herschel-ATLAS data release 1 - I. Maps, catalogues and number counts
Ivison, R. J.; Ibar, E.; Dunne, L. +11 more
We present the first major data release of the largest single key-project in area carried out in open time with the Herschel Space Observatory. The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 600 deg2 in five photometric bands - 100, 160, 250, 350 and 500 µm - with the Photoconductor Array Camera an…
Mass Measurements in Protoplanetary Disks from Hydrogen Deuteride
Henning, Th.; van Dishoeck, E. F.; Pontoppidan, K. M. +8 more
The total gas mass of a protoplanetary disk is a fundamental, but poorly determined, quantity. A new technique has been demonstrated to assess directly the bulk molecular gas reservoir of molecular hydrogen using the HD J = 1-0 line at 112 µm. In this work we present a Herschel Space Observatory 10 survey of six additional T Tauri…
