Unveiling the Obscured Formation of Stars and Galaxies: Large-Scale Legacy Surveys with a New Three Color Imaging Polarimeter on a 50-m Millimeter-Wave Telescope

这项研究计划将为位于墨西哥中部的50米大毫米望远镜(LMT)开发、建造和部署一种新的毫米波相机(称为Toltec)。主要的科学目标是对银河系和外部星系的恒星形成进行四项主要调查。外部星系调查将包括绘制宇宙中的大尺度结构图。这项工作的更广泛影响包括对本科生、研究生和仪器开发博士后的培训，这是MSIP的主要重点。为了加强参与，女天文学家将担任该项目的项目科学家和副项目科学家。该小组将介绍一系列以项目的科学和工具为中心的公共宣传活动。该相机将工作在2.1 mm(900个探测器)、1.4 mm(1800个探测器)和1.1 mm(3600个探测器)三个波段，并将提供测量线偏振的能力。根据目前的计划，在明年，覆盖直径在32米到50米之间的望远镜表面的两个外环将重新铺设，并及时进行主动控制，以便部署Toltec。计划进行四次广域遗产调查：(1)云到核遗产调查将解决与恒星初始质量函数有关的问题；(2)场到灯丝遗产调查将以最近的赫歇尔空间望远镜发现的恒星形成和磁场的作用为基础；(3)恒星形成星系的超深探测将是对红移2-10的发光红外星系群的有限混淆调查；(4)大型结构调查将利用Sunyeav Zel‘dovich效应来研究高红移的星系团的形成和动力学。

This research program will develop, construct, and deploy a new millimeter-wavelength camera (known as Toltec) for the 50m Large Millimeter Telescope (LMT), located in central Mexico. The main scientific goal is to carry out four major surveys of star formation in the Galaxy and in external galaxies. The external galaxy survey will include mapping the large scale structure in the universe. Broader impacts of the work include training of undergraduate students, graduate students, and a postdoc in instrumentation development, a major focus of MSIP. Enhancing participation, female astronomers will serve as Project Scientist and Deputy Project Scientist for the project. The team will present a series of public outreach activities centered on the science and instrumentation of the project. The camera will operate in the three bands 2.1 mm (900 detectors), 1.4mm (1800 detectors), and 1.1mm (3600 detectors), and it will offer the capability of measuring linear polarization. According to current plans, over the next year the outer two rings of the telescope surface, which cover the area between 32 m and 50 m diameter, will be resurfaced and brought under active control in time for TolTEC to be deployed. Four wide-field legacy surveys are planned: (1) The Clouds-to-Cores Legacy Survey will address questions about the stellar initial mass function;(2)nThe Fields-to-Filaments Legacy Survey will build on recent Herschel space telescope findings of the importance of filaments in star formation and the role of the magnetic field; (3)The Ultra-Deep Survey of Star-forming Galaxies will be a confusion-limited survey of the luminous infrared galaxy population over redshifts 2-10; and (4) The Large Scale Structure Survey will use the Sunyeav Zel'dovich effect to study galaxy cluster formation and dynamics at high redshifts.
