The RedMaPPer Galaxy Cluster Catalog From DES Science Verification Data
Benoit-Lévy, A.; Nichol, R. C.; D'Andrea, C. B. +87 more
We describe updates to the redMaPPer algorithm, a photometric red-sequence cluster finder specifically designed for large photometric surveys. The updated algorithm is applied to 150 {{deg}}2 of Science Verification (SV) data from the Dark Energy Survey (DES), and to the Sloan Digital Sky Survey (SDSS) DR8 photometric data set. The DES …
WATCHDOG: A Comprehensive All-sky Database of Galactic Black Hole X-ray Binaries
Heinke, C. O.; Sivakoff, G. R.; Gladstone, J. C. +1 more
With the advent of more sensitive all-sky instruments, the transient universe is being probed in greater depth than ever before. Taking advantage of available resources, we have established a comprehensive database of black hole (and black hole candidate) X-ray binary (BHXB) activity between 1996 and 2015 as revealed by all-sky instruments, scanni…
The Third Fermi GBM Gamma-Ray Burst Catalog: The First Six Years
Collazzi, Andrew C.; Preece, Robert D.; Kouveliotou, Chryssa +30 more
Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two γ-ray bursts (GRBs) every three days. Here, we present the third of a series of catalogs of GRBs detected by GBM, extending the second catalog by two more years through the middle of 2014 July. The resulting list includes 1405 t…
The Herschel Orion Protostar Survey: Spectral Energy Distributions and Fits Using a Grid of Protostellar Models
Manoj, P.; Megeath, S. T.; Watson, D. M. +12 more
We present key results from the Herschel Orion Protostar Survey: spectral energy distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in the Orion molecular clouds. This is the largest sample of protostars studied in a single, nearby star formation complex. With near-infrared photometry from 2MASS, mid- and f…
Catalog of Ultra-diffuse Galaxies in the Coma Clusters from Subaru Imaging Data
Koda, Jin; Komiyama, Yutaka; Yagi, Masafumi +1 more
We present a catalog of ultra-diffuse galaxies (UDGs) in the Coma cluster. UDGs are a subset of low surface brightness (SB) galaxies with very large effective radii defined by van Dokkum et al. We surveyed the Subaru data archive for deep Suprime-Cam/Subaru R-band images, and used data covering the 1.°7 × 2.°7 region of the Coma cluster. The data …
The VLT LEGA-C Spectroscopic Survey: The Physics of Galaxies at a Lookback Time of 7 Gyr
Wolf, C.; Brammer, G.; Rix, H. -W. +17 more
The Large Early Galaxy Census (LEGA-C) is a Public Spectroscopic Survey of ∼3200 K-band selected galaxies at redshifts z = 0.6 - 1.0 with stellar masses {M}*\gt {10}10\quad {M}⊙ , conducted with VIMOS on ESO’s Very Large Telescope. The survey is embedded in the COSMOS field (R.A. = 10h00; {decl}. = +2 {deg}). The 2…
The 2 Ms Chandra Deep Field-North Survey and the 250 ks Extended Chandra Deep Field-South Survey: Improved Point-source Catalogs
Lehmer, B. D.; Alexander, D. M.; Bauer, F. E. +4 more
We present improved point-source catalogs for the 2 Ms Chandra Deep Field-North (CDF-N) and the 250 ks Extended Chandra Deep Field-South (E-CDF-S) Surveys, implementing a number of recent improvements in Chandra source-cataloging methodology. For CDF-N/E-CDF-S, we provide a main catalog that contains 683/1003 X-ray sources detected with wavdetect …
ALMA Census of Faint 1.2 mm Sources Down to ~ 0.02 mJy: Extragalactic Background Light and Dust-poor, High-z Galaxies
Ono, Yoshiaki; Ouchi, Masami; Momose, Rieko +4 more
We present statistics of 133 faint 1.2 mm continuum sources detected in about 120 deep Atacama Large Millimeter/submillimeter Array (ALMA) pointing data that include all the archival deep data available by 2015 June. We derive number counts of 1.2 mm continuum sources down to 0.02 mJy partly with the assistance of gravitational lensing, and find t…
The IBIS Soft Gamma-Ray Sky after 1000 Integral Orbits
Hill, A. B.; Bird, A. J.; Fiocchi, M. +6 more
Here we report an all-sky soft gamma-ray source catalog based on IBIS observations performed during the first 1000 orbits of INTEGRAL. The database for the construction of the source list consists of all good-quality data available, from the launch in 2002, up to the end of 2010. This corresponds to ∼110 Ms of scientific public observations, with …
A Precise Determination of the Mid-infrared Interstellar Extinction Law Based on the APOGEE Spectroscopic Survey
Gao, Jian; Wang, Shu; Li, Aigen +3 more
A precise measure of the mid-infrared interstellar extinction law is crucial for investigating the properties of interstellar dust, especially larger-sized grains. Based on the stellar parameters derived from the SDSS-III/Apache Point Observatory Galaxy Evolution Experiment (APOGEE) spectroscopic survey, we select a large sample of G-type and K-ty…
