Mass assembly in quiescent and star-forming galaxies since z ≃ 4 from UltraVISTA
Aussel, H.; Le Floc'h, E.; Sanders, D. B. +33 more
We estimate the galaxy stellar mass function and stellar mass density for star-forming and quiescent galaxies with 0.2 < z < 4. We construct a large, deep (Ks < 24) sample of 220 000 galaxies selected using the new UltraVISTA DR1 data release. Our analysis is based on precise 30-band photometricredshifts. By comparing these pho…
The Evolution of the Stellar Mass Functions of Star-forming and Quiescent Galaxies to z = 4 from the COSMOS/UltraVISTA Survey
van Dokkum, Pieter G.; Franx, Marijn; Muzzin, Adam +8 more
We present measurements of the stellar mass functions (SMFs) of star-forming and quiescent galaxies to z = 4 using a sample of 95,675 Ks -selected galaxies in the COSMOS/UltraVISTA field. The SMFs of the combined population are in good agreement with previous measurements and show that the stellar mass density of the universe was only 5…
Phibss: Molecular Gas Content and Scaling Relations in z ~ 1-3 Massive, Main-sequence Star-forming Galaxies
Lutz, D.; Wuyts, S.; Förster Schreiber, N. M. +21 more
We present PHIBSS, the IRAM Plateau de Bure high-z blue sequence CO 3-2 survey of the molecular gas properties in massive, main-sequence star-forming galaxies (SFGs) near the cosmic star formation peak. PHIBSS provides 52 CO detections in two redshift slices at z ~ 1.2 and 2.2, with log(M *(M ⊙)) >= 10.4 and log(SFR(M
The Low-luminosity End of the Radius-Luminosity Relationship for Active Galactic Nuclei
Treu, Tommaso; Peterson, Bradley M.; Filippenko, Alexei V. +15 more
We present an updated and revised analysis of the relationship between the Hβ broad-line region (BLR) radius and the luminosity of the active galactic nucleus (AGN). Specifically, we have carried out two-dimensional surface brightness decompositions of the host galaxies of nine new AGNs imaged with the Hubble Space Telescope Wide Field Camera 3. T…
The DEEP2 Galaxy Redshift Survey: Design, Observations, Data Reduction, and Redshifts
Weiner, Benjamin J.; Conroy, Charlie; Davis, Marc +31 more
We describe the design and data analysis of the DEEP2 Galaxy Redshift Survey, the densest and largest high-precision redshift survey of galaxies at z ~ 1 completed to date. The survey was designed to conduct a comprehensive census of massive galaxies, their properties, environments, and large-scale structure down to absolute magnitude MB
A `kilonova' associated with the short-duration γ-ray burst GRB 130603B
Fruchter, A. S.; Wiersema, K.; Levan, A. J. +4 more
Short-duration γ-ray bursts are intense flashes of cosmic γ-rays, lasting less than about two seconds, whose origin is unclear. The favoured hypothesis is that they are produced by a relativistic jet created by the merger of two compact stellar objects (specifically two neutron stars or a neutron star and a black hole). This is supported by indire…
Cosmicflows-2: The Data
Dolphin, Andrew E.; Wu, Po-Feng; Shaya, Edward J. +11 more
Cosmicflows-2 is a compilation of distances and peculiar velocities for over 8000 galaxies. Numerically the largest contributions come from the luminosity-line width correlation for spirals, the Tully-Fisher relation (TFR), and the related fundamental plane relation for E/S0 systems, but over 1000 distances are contributed by methods that provide …
New Constraints on Cosmic Reionization from the 2012 Hubble Ultra Deep Field Campaign
Ono, Yoshiaki; Ouchi, Masami; Stark, Daniel P. +13 more
Understanding cosmic reionization requires the identification and characterization of early sources of hydrogen-ionizing photons. The 2012 Hubble Ultra Deep Field (UDF12) campaign has acquired the deepest infrared images with the Wide Field Camera 3 aboard Hubble Space Telescope and, for the first time, systematically explored the galaxy populatio…
The Abundance of Star-forming Galaxies in the Redshift Range 8.5-12: New Results from the 2012 Hubble Ultra Deep Field Campaign
Ono, Yoshiaki; Ouchi, Masami; Stark, Daniel P. +13 more
We present the results of the deepest search to date for star-forming galaxies beyond a redshift z ~= 8.5 utilizing a new sequence of near-infrared Wide-Field Camera 3 (WFC3/IR) images of the Hubble Ultra Deep Field (UDF). This "UDF12" campaign completed in 2012 September doubles the earlier exposures with WFC3/IR in this field and quadruples the …
CANDELS Multi-wavelength Catalogs: Source Detection and Photometry in the GOODS-South Field
Barro, Guillermo; Castellano, Marco; Ferguson, Henry C. +33 more
We present a UV to mid-infrared multi-wavelength catalog in the CANDELS/GOODS-S field, combining the newly obtained CANDELS HST/WFC3 F105W, F125W, and F160W data with existing public data. The catalog is based on source detection in the WFC3 F160W band. The F160W mosaic includes the data from CANDELS deep and wide observations as well as previous …
