Dark Energy Survey Year 1 Results: The Photometric Data Set for Cosmology
DOI: 10.3847/1538-4365/aab4f5 Bibcode: 2018ApJS..235...33D

Benoit-Lévy, A.; Bechtol, K.; Smith, M. +87 more

We describe the creation, content, and validation of the Dark Energy Survey (DES) internal year-one cosmology data set, Y1A1 GOLD, in support of upcoming cosmological analyses. The Y1A1 GOLD data set is assembled from multiple epochs of DES imaging and consists of calibrated photometric zero-points, object catalogs, and ancillary data products—e.g…

The SINS/zC-SINF Survey of z ∼ 2 Galaxy Kinematics: SINFONI Adaptive Optics-assisted Data and Kiloparsec-scale Emission-line Properties
DOI: 10.3847/1538-4365/aadd49 Bibcode: 2018ApJS..238...21F

Lutz, D.; Wuyts, S.; Cimatti, A. +29 more

We present the “SINS/zC-SINF AO survey” of 35 star-forming galaxies, the largest sample with deep adaptive optics (AO)-assisted near-infrared integral field spectroscopy at z ∼ 2. The observations, taken with SINFONI at the Very Large Telescope, resolve the Hα and [N II] emission and kinematics on scales of ∼1.5 kpc. The sample probes the massive …

The JWST Extragalactic Mock Catalog: Modeling Galaxy Populations from the UV through the Near-IR over 13 Billion Years of Cosmic History
DOI: 10.3847/1538-4365/aabcbb Bibcode: 2018ApJS..236...33W

Chevallard, Jacopo; Maseda, Michael V.; Carniani, Stefano +24 more

We present an original phenomenological model to describe the evolution of galaxy number counts, morphologies, and spectral energy distributions across a wide range of redshifts (0.2< z< 15) and stellar masses [{log}(M/{M})≥slant 6]. Our model follows observed mass and luminosity functions of both star-forming and quiescent gala…

On the Observability of Individual Population III Stars and Their Stellar-mass Black Hole Accretion Disks through Cluster Caustic Transits
DOI: 10.3847/1538-4365/aaa760 Bibcode: 2018ApJS..234...41W

Kelly, Patrick L.; Driver, Simon P.; Windhorst, Rogier A. +8 more

We summarize panchromatic Extragalactic Background Light data to place upper limits on the integrated near-infrared surface brightness (SB) that may come from Population III stars and possible accretion disks around their stellar-mass black holes (BHs) in the epoch of First Light, broadly taken from z ≃ 7-17. Theoretical predictions and recent nea…

The Resolved Stellar Populations in the LEGUS Galaxies1
DOI: 10.3847/1538-4365/aaa8e5 Bibcode: 2018ApJS..235...23S

Schaerer, D.; Östlin, G.; Herrero, A. +52 more

The Legacy ExtraGalactic UV Survey (LEGUS) is a multiwavelength Cycle 21 Treasury program on the Hubble Space Telescope. It studied 50 nearby star-forming galaxies in 5 bands from the near-UV to the I-band, combining new Wide Field Camera 3 observations with archival Advanced Camera for Surveys data. LEGUS was designed to investigate how star form…

HFF-DeepSpace Photometric Catalogs of the 12 Hubble Frontier Fields, Clusters, and Parallels: Photometry, Photometric Redshifts, and Stellar Masses
DOI: 10.3847/1538-4365/aaacce Bibcode: 2018ApJS..235...14S

Muzzin, Adam; Labbé, Ivo; van der Wel, Arjen +14 more

We present Hubble multi-wavelength photometric catalogs, including (up to) 17 filters with the Advanced Camera for Surveys and Wide Field Camera 3 from the ultra-violet to near-infrared for the Hubble Frontier Fields and associated parallels. We have constructed homogeneous photometric catalogs for all six clusters and their parallels. To further …

X-UDS: The Chandra Legacy Survey of the UKIDSS Ultra Deep Survey Field
DOI: 10.3847/1538-4365/aab9b4 Bibcode: 2018ApJS..236...48K

Papovich, Casey; Kocevski, Dale D.; Koekemoer, Anton M. +25 more

We present the X-UDS survey, a set of wide and deep Chandra observations of the Subaru-XMM Deep/UKIDSS Ultra Deep Survey (SXDS/UDS) field. The survey consists of 25 observations that cover a total area of 0.33 deg2. The observations are combined to provide a nominal depth of ∼600 ks in the central 100 arcmin2 region of the fi…

Far-ultraviolet Activity Levels of F, G, K, and M Dwarf Exoplanet Host Stars

Loyd, R. O. Parke; Redfield, Seth; France, Kevin +4 more

We present a survey of far-ultraviolet (FUV; 1150-1450 Å) emission line spectra from 71 planet-hosting and 33 non-planet-hosting F, G, K, and M dwarfs with the goals of characterizing their range of FUV activity levels, calibrating the FUV activity level to the 90-360 Å extreme-ultraviolet (EUV) stellar flux, and investigating the potential for FU…

Oesch, P. A.; Carollo, C. M.; Nelson, E. J. +15 more

We present the Hubble Deep UV Legacy Survey (HDUV), a 132-orbit imaging program with the WFC3/UVIS camera on board the Hubble Space Telescope (HST). The HDUV extends and builds on the few previous UV imaging surveys in the two GOODS/CANDELS-Deep fields to provide deep images over a total area of ∼100 arcmin2 in the two filters F275W and…

hCOSMOS: A Dense Spectroscopic Survey of r ≤ 21.3 Galaxies in the COSMOS field

Hwang, Ho Seong; Geller, Margaret J.; Damjanov, Ivana +2 more

We describe the hCOSMOS redshift survey of the COSMOS field conducted with the Hectospec spectrograph on the MMT. In the central 1 deg2, the hCOS20.6 subset of the survey is > 90 % complete to a limiting magnitude r = 20.6. The hCOSMOS survey includes 1701 new redshifts in the COSMOS field. We also use the total of 4362 new and remea…
