The Baryon Oscillation Spectroscopic Survey of SDSS-III
Weiner, Benjamin J.; Finley, Hayley; Brandt, W. N. +162 more
The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger volume than the combined efforts of all previous spectroscopic surveys of large-scale structure. BOSS uses 1.5 million luminous galaxies as faint as i = 19.9 over 10,000 deg2…
The Fourth US Naval Observatory CCD Astrograph Catalog (UCAC4)
Zacharias, N.; Finch, C. T.; Girard, T. M. +4 more
The fourth United States Naval Observatory (USNO) CCD Astrograph Catalog, UCAC4, was released in 2012 August (double-sided DVD and CDS data center Vizier catalog I/322). It is the final release in this series and contains over 113 million objects; over 105 million of them with proper motions (PMs). UCAC4 is an updated version of UCAC3 with about t…
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 Second Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars
Troja, E.; Caraveo, P. A.; Orlando, E. +208 more
This catalog summarizes 117 high-confidence >=0.1 GeV gamma-ray pulsar detections using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite. Half are neutron stars discovered using LAT data through periodicity searches in gamma-ray and radio data around LAT unassociated source positions. The 117 pulsars are eve…
The Solar Wind as a Turbulence Laboratory
Bruno, Roberto; Carbone, Vincenzo
In this review we will focus on a topic of fundamental importance for both astrophysics and plasma physics, namely the occurrence of large-amplitude low-frequency fluctuations of the fields that describe the plasma state. This subject will be treated within the context of the expanding solar wind and the most meaningful advances in this research f…
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…
