Probing the Growth of Galaxies with the Bolocam Millimeter-Wave Galaxy Survey

这个项目是一项毫米波巡天，通过探测100多个红移z1的超亮星系发出的热尘埃，直接探测早期宇宙中星系的形成。这项调查将在寻找最高红移的星系方面具有独特的效率，并被设计用于探测极其明亮的星系。这将使光学，红外和x射线观测识别的可能性最大化，并且即使没有光学光谱识别，也可以限制物体的红移。这项调查的关键是Bolocam，这是加州理工学院亚毫米波天文台的毫米波测热仪相机，具有很高的测绘速度。探测到的星系将在加州理工学院亚毫米天文台的SHARC II上进行350微米光度测定。这次巡天产生的Bolocam星系目录将为许多研究者后续的多波段观测提供丰富的来源列表。科学项目将与利用科罗拉多大学独特的菲斯克天文馆的教育和公众推广项目相结合。将编写适合公众晚上和天文学入门讲座的两部分多媒体表演。它们将展示我们对宇宙的快速发展的理解，正如微波和亚/毫米观测所揭示的：(1)“火热的大爆炸的证据”和(2)“星系的形成”。该奖项将资助一名博士研究生，并为首席研究员提供部分夏季工资，以开展科学和推广项目。

AST-0206158GlennThis program is a millimeter-wave survey that will directly probe the formation of galaxies in the early universe by detecting thermal dust emission from more than one hundred ultraluminous galaxies at redshifts z 1. The survey will be uniquely efficient at finding galaxies at the highest redshifts, and is designed to detect extremely luminous galaxies. This will maximize the likelihood of identification with optical, infrared, and X-ray observations, and allow redshifts to be constrained for objects even without optical spectroscopic identifications. The key to the survey is Bolocam, a millimeter-wave bolometer camera with high mapping speed on the Caltech Submillimeter Observatory. The detected galaxies will be followed-up with 350 micron photometry with SHARC II on the Caltech Submillimeter Observatory. The Bolocam galaxy catalog generated by this survey will provide a rich source list for follow-up multi-band observations by many investigators. The science program will be integrated with an education and public outreach program that takes advantage of the unique Fiske Planetarium at the University of Colorado. A two-part, multi-media show suitable for public nights and introductory astronomy lectures will be written. They will showcase our rapidly evolving understanding of the Universe as revealed by microwave and sub/millimeter observations: (I) "Evidence for the Fiery Big Bang" and (II) "The Formation of Galaxies". The award will support a Ph.D. graduate student and provide partial summer salary for the Principle Investigator to carry out the science and outreach programs.
