Fermi Large Area Telescope Third Source Catalog
Troja, E.; Caraveo, P. A.; Mirabal, N. +169 more
We present the third Fermi Large Area Telescope (LAT) source catalog (3FGL) of sources in the 100 MeV-300 GeV range. Based on the first 4 yr of science data from the Fermi Gamma-ray Space Telescope mission, it is the deepest yet in this energy range. Relative to the Second Fermi LAT catalog, the 3FGL catalog incorporates twice as much data, as wel…
Galaxy Clusters Discovered via the Sunyaev-Zel'dovich Effect in the 2500-Square-Degree SPT-SZ Survey
Gladders, M. D.; Schrabback, T.; Rest, A. +71 more
We present a catalog of galaxy clusters selected via their Sunyaev-Zel'dovich (SZ) effect signature from 2500 deg2 of South Pole Telescope (SPT) data. This work represents the complete sample of clusters detected at high significance in the 2500 deg2 SPT-SZ survey, which was completed in 2011. A total of 677 (409) cluster can…
The MOSFIRE Deep Evolution Field (MOSDEF) Survey: Rest-frame Optical Spectroscopy for ~1500 H-selected Galaxies at 1.37 < z < 3.8
Siana, Brian; van Dokkum, Pieter G.; Conroy, Charlie +21 more
In this paper we present the MOSFIRE Deep Evolution Field (MOSDEF) survey. The MOSDEF survey aims to obtain moderate-resolution (R = 3000-3650) rest-frame optical spectra (∼3700-7000 Å) for ∼1500 galaxies at 1.37≤ z≤ 3.80 in three well-studied CANDELS fields: AEGIS, COSMOS, and GOODS-N. Targets are selected in three redshift intervals: 1.37≤ z≤ 1.…
Morphologies of ∼190,000 Galaxies at z = 0-10 Revealed with HST Legacy Data. I. Size Evolution
Ouchi, Masami; Harikane, Yuichi; Shibuya, Takatoshi
We present the redshift evolution of the galaxy effective radius re obtained from the Hubble Space Telescope (HST) samples of ∼190,000 galaxies at z = 0-10. Our HST samples consist of 176,152 photo-z galaxies at z = 0-6 from the 3D-HST+CANDELS catalog and 10,454 Lyman break galaxies (LBGs) at z = 4-10 identified in the Cosmic Assembly N…
Calibration of the NuSTAR High-energy Focusing X-ray Telescope.
An, Hongjun; Hailey, Charles J.; Walton, Dominic J. +19 more
We present the calibration of the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray satellite. We used the Crab as the primary effective area calibrator and constructed a piece-wise linear spline function to modify the vignetting response. The achieved residuals for all off-axis angles and energies, compared to the assumed spectrum, are typical…
Stellar Masses and Star Formation Rates for 1M Galaxies from SDSS+WISE
van der Wel, Arjen; Rix, Hans-Walter; da Cunha, Elisabete +1 more
We combine Sloan Digitital Sky Survey (SDSS) and WISE photometry for the full SDSS spectroscopic galaxy sample, creating spectral energy distributions (SEDs) that cover λ = 0.4-22 µm for an unprecedentedly large and comprehensive sample of 858,365 present-epoch galaxies. Using MAGPHYS, we then simultaneously and consistently model both the a…
A Catalog of Visual-like Morphologies in the 5 CANDELS Fields Using Deep Learning
Kartaltepe, J. S.; Faber, S. M.; Huertas-Company, M. +12 more
We present a catalog of visual-like H-band morphologies of ∼50.000 galaxies (Hf160w < 24.5) in the 5 CANDELS fields (GOODS-N, GOODS-S, UDS, EGS, and COSMOS). Morphologies are estimated using Convolutional Neural Networks (ConvNets). The median redshift of the sample is < z> ∼ 1.25. The algorithm is trained on GOODS-S, for which…
Noise-based Detection and Segmentation of Nebulous Objects
Ichikawa, Takashi; Akhlaghi, Mohammad
A noise-based non-parametric technique for detecting nebulous objects, for example, irregular or clumpy galaxies, and their structure in noise is introduced. “Noise-based” and “non-parametric” imply that this technique imposes negligible constraints on the properties of the targets and that it employs no regression analysis or fittings. The sub-sk…
The FMOS-COSMOS Survey of Star-forming Galaxies at z~1.6. III. Survey Design, Performance, and Sample Characteristics
Daddi, E.; Rodighiero, G.; Ilbert, O. +28 more
We present a spectroscopic survey of galaxies in the COSMOS field using the Fiber Multi-object Spectrograph (FMOS), a near-infrared instrument on the Subaru Telescope. Our survey is specifically designed to detect the Hα emission line that falls within the H-band (1.6-1.8 µm) spectroscopic window from star-forming galaxies with 1.4 < z &l…
AEGIS-X: Deep Chandra Imaging of the Central Groth Strip
Barmby, P.; Ivison, R. J.; Cooper, M. C. +22 more
We present the results of deep Chandra imaging of the central region of the Extended Groth Strip, the AEGIS-X Deep (AEGIS-XD) survey. When combined with previous Chandra observations of a wider area of the strip, AEGIS-X Wide (AEGIS-XW), these provide data to a nominal exposure depth of 800 ks in the three central ACIS-I fields, a region of approx…
