CANDELS: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey
Finkelstein, Steven L.; Bell, Eric F.; Castellano, Marco +104 more
The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) is designed to document the first third of galactic evolution, over the approximate redshift (z) range 8-1.5. It will image >250,000 distant galaxies using three separate cameras on the Hubble Space Telescope, from the mid-ultraviolet to the near-infrared, and will fin…
CANDELS: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey—The Hubble Space Telescope Observations, Imaging Data Products, and Mosaics
Finkelstein, Steven L.; Bell, Eric F.; Castellano, Marco +121 more
This paper describes the Hubble Space Telescope imaging data products and data reduction procedures for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). This survey is designed to document the evolution of galaxies and black holes at z ≈ 1.5-8, and to study Type Ia supernovae at z > 1.5. Five premier multi-wavelengt…
Supernova Constraints and Systematic Uncertainties from the First Three Years of the Supernova Legacy Survey
Sullivan, M.; Lidman, C.; González-Gaitán, S. +33 more
We combine high-redshift Type Ia supernovae from the first three years of the Supernova Legacy Survey (SNLS) with other supernova (SN) samples, primarily at lower redshifts, to form a high-quality joint sample of 472 SNe (123 low-z, 93 SDSS, 242 SNLS, and 14 Hubble Space Telescope). SN data alone require cosmic acceleration at >99.999% confiden…
The Chandra Deep Field-South Survey: 4 Ms Source Catalogs
Smail, I.; Lehmer, B. D.; Hornschemeier, A. E. +22 more
We present source catalogs for the 4 Ms Chandra Deep Field-South (CDF-S), which is the deepest Chandra survey to date and covers an area of 464.5 arcmin2. We provide a main Chandra source catalog, which contains 740 X-ray sources that are detected with WAVDETECT at a false-positive probability threshold of 10-5 in at least on…
The First Hundred Brown Dwarfs Discovered by the Wide-field Infrared Survey Explorer (WISE)
Kartaltepe, Jeyhan S.; Tsai, Chao-Wei; Cushing, Michael C. +38 more
We present ground-based spectroscopic verification of 6 Y dwarfs (see also Cushing et al.), 89 T dwarfs, 8 L dwarfs, and 1 M dwarf identified by the Wide-field Infrared Survey Explorer (WISE). Eighty of these are cold brown dwarfs with spectral types >=T6, six of which have been announced earlier by Mainzer et al. and Burgasser et al. We presen…
The Galactic O-Star Spectroscopic Survey. I. Classification System and Bright Northern Stars in the Blue-violet at R ~ 2500
Maíz Apellániz, J.; Alfaro, E. J.; Barbá, R. H. +5 more
We present the first installment of a massive spectroscopic survey of Galactic O stars, based on new, high signal-to-noise ratio, R ~ 2500 digital observations from both hemispheres selected from the Galactic O-Star Catalog of Maíz Apellániz et al. and Sota et al. The spectral classification system is rediscussed and a new atlas is presented, whic…
The Hubble Space Telescope Wide Field Camera 3 Early Release Science Data: Panchromatic Faint Object Counts for 0.2-2 µm Wavelength
Hathi, Nimish P.; Koekemoer, Anton M.; Mutchler, Max +36 more
We describe the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) Early Release Science (ERS) observations in the Great Observatories Origins Deep Survey (GOODS) South field. The new WFC3 ERS data provide calibrated, drizzled mosaics in the UV filters F225W, F275W, and F336W, as well as in the near-IR filters F098M (Ys ), F125W (J…
The GHOSTS Survey. I. Hubble Space Telescope Advanced Camera for Surveys Data
Ferguson, H. C.; Dalcanton, J. J.; Bell, E. F. +15 more
We present an overview of the GHOSTS survey, the largest study to date of the resolved stellar populations in the outskirts of disk galaxies. The sample consists of 14 disk galaxies within 17 Mpc, whose outer disks and halos are imaged with the Hubble Space Telescope Advanced Camera for Surveys (ACS). In the first paper of this series, we describe…
The Next Generation Atlas of Quasar Spectral Energy Distributions from Radio to X-Rays
Hines, Dean C.; Green, Richard F.; Gallagher, Sarah C. +14 more
We have produced the next generation of quasar spectral energy distributions (SEDs), essentially updating the work of Elvis et al. by using high-quality data obtained with several space- and ground-based telescopes, including NASA's Great Observatories. We present an atlas of SEDs of 85 optically bright, non-blazar quasars over the electromagnetic…
Wide-field Precision Kinematics of the M87 Globular Cluster System
Spitler, Lee R.; Romanowsky, Aaron J.; Brodie, Jean P. +6 more
We present the most extensive combined photometric and spectroscopic study to date of the enormous globular cluster (GC) system around M87, the central giant elliptical galaxy in the nearby Virgo Cluster. Using observations from DEIMOS and the Low Resolution Imaging Spectrometer at Keck, and Hectospec on the Multiple Mirror Telescope, we derive ne…
