From the Local Universe to the First Massive Galaxies: the New IRAS Surveys for the 21st Century

我们请求两个PDRA将本地宇宙尘埃星系群与早期宇宙中的第一个大质量星系联系起来，使用来自两个新的主要调查天文设施的数据：英国詹姆斯克拉克麦克斯韦望远镜上的SCUBA-2相机和日本ASTRO-F太空望远镜。在本地宇宙（即在低红移），星系的综合属性（如尘埃质量，温度）是星系内的平均物理性质的可靠指标？在高红移，只有综合性能;我们解决远红外次毫米映射本地星系可以解决这个问题。测量高红移演化的红移z=0光度函数是什么？高红移粒子的模板光谱能量分布是什么？在高红移下，可观测宇宙中最明亮的星系是什么？活动星系核与最大质量球状体中的恒星质量集合体之间的联系是什么？我们申请资金用于（a）支持高红移发光物体的探测（0.5 PDRA FTE）和本地扩展星系（0.5 PDRA FTE）使用ASTRO-F全天巡天，我们有保证的时间数据访问;（B）0.5个PDRA全职工作人员，以支持与SCUBA-2全天空巡天密切相关的工作，Serjeant是其中的协调员，以及（c）0.5个PDRA FTE，以支持与SCUBA-2遗留调查“本地宇宙中星系的物理过程”密切相关的工作，Serjeant也是该调查的协调员。这些主要的广域中/远红外和亚毫米遗留调查将在未来几十年中发挥IRAS在世纪后期发挥的主导作用; IRAS自1983年以来至今已产生超过44，000次引用，其在天体物理领域的巨大范围内的生产力仍然没有减弱。PDRA将担任SCUBA-2全天巡天计划的管道管理员，并从Serjeant手中接管河外档案联系人的角色。这里要求的及时PDRA支持对于快速向公众提供SCUBA-2遗留调查精细数据产品（利用我们在SCUBA-1 HDF-N，8 mJy和SHADES调查中的广泛专业知识）以及在ASTRO-F保证时间的专有期间及时科学利用ASTRO-F全天调查至关重要。时间表要求从一开始就有一个具有高级技能的人（例如，在ASTRO-F第一阶段全天空调查的中间开始，以及在SCUBA-2调试开始的前后），因此这项工作显然不可能由博士生进行。

We request two PDRAs to link the local Universe dusty galaxy population to the first massive galaxies in the early Universe, using data from two new major survey astronomical facilities: the SCUBA-2 camera on the UK's James Clerk Maxwell Telescope, and the Japanese ASTRO-F Space Telescope. In the local Universe (i.e. at low redshift), are integrated properties of galaxies (e.g. dust mass, temperature) reliable indicators of the mean physical properties within galaxies? At high-redshift, only integrated properties are available; our resolved far-IR-sub-mm mapping of local galaxies can address this. What are the redshift z=0 luminosity functions from which one measures the high-redshift evolution? What are the template spectral energy distributions for the high-redshift population? At high redshifts, what are the most luminous galaxies in the observable Universe? What are the links between active galactic nuclei and the stellar mass assembly in the most massive spheroids? We request funding for (a) supporting the detection of high-redshift luminous objects (0.5 PDRA FTE) and local extended galaxies (0.5 PDRA FTE) using the ASTRO-F All-Sky Survey, to which we have Guaranteed Time data access; (b) 0.5 PDRA FTE to support closely related work for the SCUBA-2 All Sky Survey (SASSy) in which Serjeant is a Co-ordinator, and (c) 0.5 PDRA FTE to support closely related work for the SCUBA-2 Legacy Survey 'Physical Processes in Galaxies in the Local Universe' in which Serjeant is also a Co-ordinator. These major wide-area mid/far-infrared and sub-mm legacy surveys will play the dominant role in the coming decades that IRAS played in the late 20th century; IRAS has generated >44,000 citations to date since 1983 and its productivity in an enormous range of astrophysical areas is still undiminished. The PDRA will assume the role of Pipeline Manager for the SCUBA-2 All Sky Survey and take over the role of Extragalactic Archive Contact from Serjeant. The timely PDRA support requested here is essential for the rapid public delivery of SCUBA-2 Legacy Survey refined data products (capitalising on our extensive expertise in the SCUBA-1 HDF-N, 8mJy and SHADES surveys), and for the timely science exploitation of the ASTRO-F All-Sky Survey during the proprietary period of the ASTRO-F guaranteed time. The timescales require a person with advanced skills from the outset (e.g. commencing in the middle of the ASTRO-F Phase 1 all-sky survey, and around the start of SCUBA-2 commissioning) and so it is clearly impossible for this work to be conducted by a PhD student.
