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

AST-0206158Glenn本计划是一项毫米波探测计划，将通过探测100多个红移为z 1的超轻星系的热尘埃发射，直接探测早期宇宙中星系的形成。该计划将在寻找红移最高的星系方面独一无二地有效，并被设计为探测极亮星系。这将最大限度地利用光学、红外和X射线观测进行识别，并允许即使在没有光学光谱识别的情况下也可以限制物体的红移。这项调查的关键是Bolocam，这是加州理工大学亚毫米天文台上的一款具有高速测绘速度的毫米波测辐射热计相机。探测到的星系将在加州理工大学亚毫米天文台使用SHARC II进行350微米光度测量。此次调查产生的Bolocam星系星表将为许多研究人员后续的多波段观测提供丰富的来源清单。科学计划将与利用科罗拉多大学独特的菲斯克天文馆的教育和公共推广计划相结合。将编写一部适合公共夜晚和天文学入门讲座的分两部分的多媒体节目。它们将展示我们对宇宙的快速发展的理解，如微波和亚/毫米观测所揭示的：(I)“炽热大爆炸的证据”和(Ii)“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暑期工资，以开展科学和推广计划。

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.
