论文摘要
我们提出了一个大约100,000 MUV的模拟图像目录= -22.5至-19.6 Mag星系，Z = 7-12的Mag Galaxies来自Bluetides宇宙学模拟。我们使用James Webb（JWST），Hubble，Roman和Euclid Space望远镜以及Subaru和Vista创建每个星系的模拟图像，并具有一系列近红外过滤器。我们在模拟图像上执行光度法，以估计这些仪器在检测高Z星系方面的成功。我们预测，JWST在检测高Z星系方面将具有前所未有的能力，其完整性极限至少比Vista和Subaru的幅度至少为2.5个大小，而Hubble比Hubble的幅度为1.1，而0.9比Roman的幅度为0.9，相同的波长和曝光时间。专注于JWST，我们考虑了一系列的曝光时间和过滤器，并发现Nircam F356W和F277W过滤器将检测到最微弱的星系，在10KS暴露中，M = 27.4 mag的完整性为95％。我们还预测了即将进行的JWST成像调查将发现的高Z星系数量。我们预测，Cosmos-Web调查将根据其较大的调查区域检测到约1000 Muv <-20.1 mag星系。 Jades-Medium将在Z <8.5处检测几乎100％的MUV <-20 mag星系，但由于其较小的调查区域，它将在6.5 <Z <7.5时仅检测到〜100个这些星系。宇宙差异会导致每个调查的预测星系数量范围很大，这在较小的调查中更为明显，例如CEORS和PEARLS NEP NEP和GOODS-S FIELDS。
We present a mock image catalogue of ~100,000 MUV=-22.5 to -19.6 mag galaxies at z=7-12 from the BlueTides cosmological simulation. We create mock images of each galaxy with the James Webb (JWST), Hubble, Roman, and Euclid Space Telescopes, as well as Subaru, and VISTA, with a range of near- and mid-infrared filters. We perform photometry on the mock images to estimate the success of these instruments for detecting high-z galaxies. We predict that JWST will have unprecedented power in detecting high-z galaxies, with a 95% completeness limit at least 2.5 magnitudes fainter than VISTA and Subaru, 1.1 magnitudes fainter than Hubble, and 0.9 magnitudes fainter than Roman, for the same wavelength and exposure time. Focusing on JWST, we consider a range of exposure times and filters, and find that the NIRCam F356W and F277W filters will detect the faintest galaxies, with 95% completeness at m=27.4 mag in 10ks exposures. We also predict the number of high-z galaxies that will be discovered by upcoming JWST imaging surveys. We predict that the COSMOS-Web survey will detect ~1000 MUV<-20.1 mag galaxies at 6.5<z<7.5, by virtue of its large survey area. JADES-Medium will detect almost 100% of MUV<-20 mag galaxies at z<8.5 due to its significant depth, however with its smaller survey area it will detect only ~100 of these galaxies at 6.5<z<7.5. Cosmic variance results in a large range in the number of predicted galaxies each survey will detect, which is more evident in smaller surveys such as CEERS and the PEARLS NEP and GOODS-S fields.
