论文摘要
超大深度边界领域和传统观测（布法罗）是101轨道 + 101平行周期25 Hubble Space望远镜财政部计划，从2018 - 2020年开始获取数据。 Buffalo将在WFC3/IR F105W，F125W和F160W和ACS/WFC F606W和F814W和F814W周围的每个HFF群集和侧翼磁场中的每个WFC3/IR F105W和F160W和F160W和F160W和F160W和F160W和F814W中扩展现有的覆盖范围。 HST尚未观察到这个额外的区域，但已经被包括Spitzer和Chandra在内的深层多波长数据集所覆盖。与原始的HFF程序一样，Buffalo旨在利用从大型簇到同时找到高红移星系的重力镜头，否则这些星系将低于HST检测限，并模型前景簇来研究暗物质和星系组件的属性。扩展的区域将为大型HFF群集郊区的高红移和星系组件的宇宙差异提供第一个机会。保留五个额外的轨道以进行瞬态随访。水牛数据包括镶嵌，增值目录和集群质量分布模型，将定期发布，因为六个单独的簇完成了观测值和分析。
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. BUFFALO will expand existing coverage of the Hubble Frontier Fields (HFF) in WFC3/IR F105W, F125W, and F160W and ACS/WFC F606W and F814W around each of the six HFF clusters and flanking fields. This additional area has not been observed by HST but is already covered by deep multi-wavelength datasets, including Spitzer and Chandra. As with the original HFF program, BUFFALO is designed to take advantage of gravitational lensing from massive clusters to simultaneously find high-redshift galaxies which would otherwise lie below HST detection limits and model foreground clusters to study properties of dark matter and galaxy assembly. The expanded area will provide a first opportunity to study both cosmic variance at high redshift and galaxy assembly in the outskirts of the large HFF clusters. Five additional orbits are reserved for transient followup. BUFFALO data including mosaics, value-added catalogs and cluster mass distribution models will be released via MAST on a regular basis, as the observations and analysis are completed for the six individual clusters.
