3D-HST WFC3-selected Photometric Catalogs in the Five CANDELS/3D-HST Fields: Photometry, Photometric Redshifts, and Stellar Masses
Maseda, Michael V.; van Dokkum, Pieter G.; Franx, Marijn +24 more
The 3D-HST and CANDELS programs have provided WFC3 and ACS spectroscopy and photometry over ≈900 arcmin2 in five fields: AEGIS, COSMOS, GOODS-North, GOODS-South, and the UKIDSS UDS field. All these fields have a wealth of publicly available imaging data sets in addition to the Hubble Space Telescope (HST) data, which makes it possible t…
The McGill Magnetar Catalog
Kaspi, V. M.; Olausen, S. A.
We present a catalog of the 26 currently known magnetars and magnetar candidates. We tabulate astrometric and timing data for all catalog sources, as well as their observed radiative properties, particularly the spectral parameters of the quiescent X-ray emission. We show histograms of the spatial and timing properties of the magnetars, comparing …
The Galactic O-Star Spectroscopic Survey (GOSSS). II. Bright Southern Stars
Maíz Apellániz, J.; Alfaro, E. J.; Barbá, R. H. +5 more
We present the second installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R ~ 2500 digital observations from both hemispheres selected from the Galactic O-Star Catalog (GOSC). In this paper we include bright stars and other objects drawn mostly from the first version of GO…
An Atlas of Galaxy Spectral Energy Distributions from the Ultraviolet to the Mid-infrared
Imanishi, Masatoshi; Peek, J. E. G.; Moustakas, John +6 more
We present an atlas of 129 spectral energy distributions for nearby galaxies, with wavelength coverage spanning from the ultraviolet to the mid-infrared. Our atlas spans a broad range of galaxy types, including ellipticals, spirals, merging galaxies, blue compact dwarfs, and luminous infrared galaxies. We have combined ground-based optical drift-s…
The Panchromatic Hubble Andromeda Treasury. X. Ultraviolet to Infrared Photometry of 117 Million Equidistant Stars
Bell, Eric F.; Monachesi, Antonela; Dolphin, Andrew E. +16 more
We have measured stellar photometry with the Hubble Space Telescope Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys in near ultraviolet (F275W, F336W), optical (F475W, F814W), and near infrared (F110W, F160W) bands for 117 million resolved stars in M31. As part of the Panchromatic Hubble Andromeda Treasury survey, we measured photometry…
The Second Fermi GBM Gamma-Ray Burst Catalog: The First Four Years
Collazzi, Andrew C.; Goldstein, Adam; Preece, Robert D. +30 more
This is the second of a series of catalogs of gamma-ray bursts (GRBs) observed with the Fermi Gamma-ray Burst Monitor (GBM). It extends the first two-year catalog by two more years, resulting in an overall list of 953 GBM triggered GRBs. The intention of the GBM GRB catalog is to provide information to the community on the most important observabl…
The Third Gravitational Lensing Accuracy Testing (GREAT3) Challenge Handbook
Schrabback, Tim; Miyatake, Hironao; Leauthaud, Alexie +28 more
The GRavitational lEnsing Accuracy Testing 3 (GREAT3) challenge is the third in a series of image analysis challenges, with a goal of testing and facilitating the development of methods for analyzing astronomical images that will be used to measure weak gravitational lensing. This measurement requires extremely precise estimation of very small gal…
1SXPS: A Deep Swift X-Ray Telescope Point Source Catalog with Light Curves and Spectra
Tagliaferri, G.; Gehrels, N.; Pagani, C. +9 more
We present the 1SXPS (Swift-XRT point source) catalog of 151,524 X-ray point sources detected by the Swift-XRT in 8 yr of operation. The catalog covers 1905 deg2 distributed approximately uniformly on the sky. We analyze the data in two ways. First we consider all observations individually, for which we have a typical sensitivity of ~3 …
The Herschel Stripe 82 Survey (HerS): Maps and Early Catalog
Doré, O.; Scott, D.; Jogee, S. +36 more
We present the first set of maps and band-merged catalog from the Herschel Stripe 82 Survey (HerS). Observations at 250, 350, and 500 µm were taken with the Spectral and Photometric Imaging Receiver instrument aboard the Herschel Space Observatory. HerS covers 79 deg2 along the SDSS Stripe 82 to an average depth of 13.0, 12.9, and…
X-Ray Emission from Magnetic Massive Stars
Wade, Gregg A.; Nazé, Yaël; ud-Doula, Asif +4 more
Magnetically confined winds of early-type stars are expected to be sources of bright and hard X-rays. To clarify the systematics of the observed X-ray properties, we have analyzed a large series of Chandra and XMM-Newton observations, corresponding to all available exposures of known massive magnetic stars (over 100 exposures covering ~60% of star…
