The CANDELS/SHARDS Multiwavelength Catalog in GOODS-N: Photometry, Photometric Redshifts, Stellar Masses, Emission-line Fluxes, and Star Formation Rates
Barro, Guillermo; Pérez-González, Pablo G.; Castellano, Marco +52 more
We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts, and stellar parameters derived from the analysis of the multiwavelength data. The catalog contains 35,445 sources over the 171 arcmin2 of the CANDELS F160W mosaic…
The Hubble Legacy Field GOODS-S Photometric Catalog
Franx, Marijn; Mowla, Lamiya; Labbé, Ivo +12 more
This manuscript describes the public release of the Hubble Legacy Fields (HLF) project photometric catalog for the extended GOODS-South region from the Hubble Space Telescope (HST) archival program AR-13252. The analysis is based on the version 2.0 HLF data release that now includes all ultraviolet (UV) imaging, combining three major UV surveys. T…
Microlensing Optical Depth and Event Rate toward the Galactic Bulge from 8 yr of OGLE-IV Observations
Udalski, Andrzej; Mróz, Przemek; Szymański, Michał K. +9 more
The number and properties of observed gravitational microlensing events depend on the distribution and kinematics of stars and other compact objects along the line of sight. In particular, precise measurements of the microlensing optical depth and event rate toward the Galactic bulge enable strict tests of competing models of the Milky Way. Previo…
Automated Mining of the ALMA Archive in the COSMOS Field (A3COSMOS). I. Robust ALMA Continuum Photometry Catalogs and Stellar Mass and Star Formation Properties for ∼700 Galaxies at z = 0.5-6
Bondi, M.; Magnelli, B.; Vaccari, M. +21 more
The rich information on (sub)millimeter dust continuum emission from distant galaxies in the public Atacama Large Millimeter/submillimeter Array (ALMA) archive is contained in thousands of inhomogeneous observations from individual PI-led programs. To increase the usability of these data for studies deepening our understanding of galaxy evolution,…
Rates and Properties of Supernovae Strongly Gravitationally Lensed by Elliptical Galaxies in Time-domain Imaging Surveys
Nugent, Peter E.; Goobar, Ariel; Goldstein, Daniel A.
Supernovae that are strongly gravitationally lensed (gLSNe) by elliptical galaxies are powerful probes of astrophysics and cosmology that will be discovered systematically by wide-field, high-cadence imaging surveys such as the Zwicky Transient Facility (ZTF) and the Large Synoptic Survey Telescope (LSST). Here we use pixel-level simulations that …
The Massive and Distant Clusters of WISE Survey. I. Survey Overview and a Catalog of >2000 Galaxy Clusters at z ≃ 1
Chambers, Kenneth C.; Magnier, Eugene; Wright, Edward L. +23 more
We present the Massive and Distant Clusters of WISE Survey (MaDCoWS), a search for galaxy clusters at 0.7 ≲ z ≲ 1.5 based upon data from the Wide-field Infrared Survey Explorer (WISE) mission. MaDCoWS is the first cluster survey capable of discovering massive clusters at these redshifts over the full extragalactic sky. The search is divided into t…
Col-OSSOS: The Colors of the Outer Solar System Origins Survey
Wang, Shiang-Yu; Marsset, Michaël; Fraser, Wesley C. +15 more
The Colours of the Outer Solar System Origins Survey is acquiring near-simultaneous g, r, and J photometry of unprecedented precision with the Gemini North Telescope, targeting nearly 100 trans-Neptunian objects (TNOs) brighter than m r = 23.6 mag discovered in the Outer Solar System Origins Survey. Combining the optical and near-infr…
Transition Probabilities of Sc I and Sc II and Scandium Abundances in the Sun, Arcturus, and HD 84937
Sneden, C.; Wood, M. P.; Lawler, J. E. +3 more
New branching fraction (BF) measurements for lines of Sc I and Sc II from 24 Fourier transform spectra calibrated using standard lamps and the Ar branching ratio method are reported. The BFs for 259 lines are converted to absolute atomic transition probabilities using published radiative lifetimes from laser-induced fluorescence measurements. Deta…
A Census of Early-phase High-mass Star Formation in the Central Molecular Zone
Ott, Jürgen; Lu, Xing; Henshaw, Jonathan D. +13 more
We present new observations of the C-band continuum emission and masers to assess high-mass (>8 {M}⊙ ) star formation at early evolutionary phases in the inner 200 pc of the Central Molecular Zone (CMZ) of the Galaxy. The continuum observation is complete to free-free emission from stars above 10-11 {M}⊙ in 91% of the cov…
Subpercent Photometry: Faint DA White Dwarf Spectrophotometric Standards for Astrophysical Observatories
Rest, Armin; Matheson, Thomas; Points, Sean +18 more
We have established a network of 19 faint (16.5 mag < V < 19 mag) northern and equatorial DA white dwarfs (WDs) as spectrophotometric standards for present and future wide-field observatories. Our analysis infers spectral energy distribution (SED) models for the stars that are tied to the three CALSPEC primary standards. Our SED models are c…
