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…
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…
CANDELS Visual Classifications: Scheme, Data Release, and First Results
Bell, Eric F.; Castellano, Marco; Kartaltepe, Jeyhan S. +49 more
We have undertaken an ambitious program to visually classify all galaxies in the five CANDELS fields down to H < 24.5 involving the dedicated efforts of over 65 individual classifiers. Once completed, we expect to have detailed morphological classifications for over 50,000 galaxies spanning 0 < z < 4 over all the fields, with classificati…
Galaxy Mergers Drive Shocks: An Integral Field Study of GOALS Galaxies
Kewley, L. J.; Dopita, M. A.; Rich, J. A.
We present an integral field spectroscopic study of radiative shocks in 27 nearby ultraluminous and luminous infrared galaxies (U/LIRGs) from the Great Observatory All-sky LIRG Survey, a subset of the Revised Bright Galaxy Sample. Our analysis of the resolved spectroscopic data from the Wide Field Spectrograph focuses on determining the detailed p…
OGLE-III Microlensing Events and the Structure of the Galactic Bulge
Udalski, Andrzej; Szymański, Michał K.; Skowron, Jan +9 more
We present and study the largest and most comprehensive catalog of microlensing events ever constructed. The sample of standard microlensing events comprises 3718 unique events from 2001-2009 with 1409 events that had not been detected before in real-time by the Early Warning System of the Optical Gravitational Lensing Experiment. The search pipel…
