The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) is designed to document the first third of galactic evolution, over the approximate redshift (z) range 8--1.5. It will image >250,000 distant galaxies using three separate cameras on the Hubble Space Telescope, from the mid-ultraviolet to the near-infrared, and will find and measure Type Ia supernovae at z>1.5 to test their accuracy as standardizable candles for cosmology. Five premier multi-wavelength sky regions are selected, each with extensive ancillary data. The use of five widely separated fields mitigates cosmic variance and yields statistically robust and complete samples of galaxies down to a stellar mass of 10^9 M_\odot to z \approx 2, reaching the knee of the ultraviolet luminosity function (UVLF) of galaxies to z \approx 8. The survey covers approximately 800 arcmin^2 and is divided into two parts. The CANDELS/Deep survey (5σ point-source limit H=27.7 mag) covers \sim 125 arcmin^2 within GOODS-N and GOODS-S. The CANDELS/Wide survey includes GOODS and three additional fields (EGS, COSMOS, and UDS) and covers the full area to a 5σ point-source limit of H \gtrsim 27.0 mag. Together with the Hubble Ultra Deep Fields, the strategy creates a three-tiered "wedding cake" approach that has proven efficient for extragalactic surveys. Data from the survey are nonproprietary and are useful for a wide variety of science investigations. In this paper, we describe the basic motivations for the survey, the CANDELS team science goals and the resulting observational requirements, the field selection and geometry, and the observing design. The Hubble data processing and products are described in a companion paper.
S-CANDELS: The Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Survey. Survey Design, Photometry, and Deep IRAC Source Counts
斯皮策宇宙大会深近红外河外遗产调查(S-CANDELS; PI G。Fazio)是一个第8周期的探索计划,旨在探测非常高红移(z > 5)的星系。为了减轻宇宙变化的影响,并利用哈勃空间望远镜多周期财政计划CANDELS在多个波段的深度同延覆盖,S-CANDELS在五个相距甚远的河外区域进行:UKIDSS超深巡天、扩展钱德拉深场南、COSMOS、HST深场北和扩展格罗斯带。S-CANDELS建立在斯皮策扩展深度调查(SEDS)现有的这些领域的覆盖范围之上,将积分时间从12小时增加到总共50小时,但在较小的区域内,0.16平方度。额外的深度显著增加了微弱星等下的勘测完整性。本文介绍了S-CANDELS调查的设计、处理和公开提供的数据产品。我们目前的IRAC双波段3.6+4.5微米目录达到26.5 AB MAG的深度。深IRAC计数的大约135,000个星系检测的S-CANDELS是一致的模型的基础上已知的星系种群。比早期斯皮策/IRAC调查更深的深度增加并没有揭示离散源对弥漫的宇宙红外背景(CIB)的显着额外贡献。因此,它仍然是正确的,只有大约一半的估计CIB通量从COBE/DIRBE解决。
CANDELS: The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey - The Hubble Space Telescope Observations, Imaging Data Products and Mosaics
We present results from a search for gravitationally lensed galaxies present in the Hubble Space Telescope (HST)/Wide Field Camera-3 (WFC3) images of the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS). We present one bona fide lens system in UDS and two compact lens candidates in the GOODS-S field. The lensing system in UDS involves two background galaxies, one at z=1.847 lensed to an arc and a counterimage, and the second at a photometric redshift of z=2.32^{+0.10}_{-0.06} lensed to a double image. We reconstruct the lensed sources in the source plane and find in each of t…

Deep Extragalactic VIsible Legacy Survey (DEVILS): Evolution of the $σ_{\mathrm{SFR}}$-M$_{\star}$ relation and implications for self-regulated star formation
我们提出的恒星形成色散恒星质量关系($σ_{SFR}$ -M $_{\star}$)的演变在魔鬼D10地区使用新的测量使用ProSpect光谱能量分布拟合代码。我们发现,$σ_{SFR}$ -M $_{\star}$在中等恒星质量从0.1<z<0.7的一些度量,包括使用去卷积的本征色散的特征“U形”。这种关系的物理解释是随机的恒星形成和恒星反馈的组合造成大的散射在低恒星质量和AGN反馈造成不对称的散射在高恒星质量。因此,这种分布的形状及其演变编码了有关影响恒星形成,反馈和星系生命周期的天体物理过程的详细信息。我们发现,最小值$σ_{SFR}$出现的恒星质量随红移线性演化,随着回望时间的增加,恒星质量向更高的恒星质量移动,并跟踪恒星形成序列中的周转。这个最小的$σ_{SFR}$点也被发现出现在一个固定的比恒星形成率(sSFR)在所有的历元(sSFR~10 $^{-9.6}$ yr $^{-1}$)。物理解释是,存在一个最大的sSFR,星系可以在内部自我调节的恒星形成的紧密序列。在较高的sSFR,随机恒星过程开始导致星系被推到恒星形成序列的上方和下方,导致SFR分散增加。随着宇宙的演化,更高比例的星系将下降到低于这个sSFR阈值,导致恒星形成序列的低恒星质量端的分散度随着时间的推移而减少。
Evidence for Infrared-Faint Radio Sources as z > 1 Radio-Loud AGN
暗射电源(英语:Inferred-Faint Radio Source,缩写IFRS)是在澳大利亚望远镜大区域巡天(英语:Australia Telescope Large Area Survey)中发现的一类射电源,在斯皮策广域河外红外线巡天(英语:Spitzer Wide-area Infrared Extragaltic)中没有可观测到的中红外线对应物。扩展后的Chandra Deep Field South现在有更深的斯皮策成像(3.6至70微米),来自一些传统的调查。我们报告了两个IFRS源在IRAC图像中的检测。另外两个IFRS的未检测允许我们限制源类型。对这些天体的SED的详细模拟表明,它们与高红移(z > 1)活动星系核相一致。
