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.

该研究计划将为位于墨西哥中部的50米大型毫米波望远镜（LMT）开发、建造和部署一台新的毫米波相机（称为Toltec）。主要的科学目标是对银河系和外部星系中的星星形成进行四次重大调查。 外部星系调查将包括绘制宇宙中的大尺度结构。这项工作的更广泛的影响包括培训本科生，研究生和仪器开发博士后，MSIP的一个主要重点。 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。该团队将围绕该项目的科学和仪器开展一系列公共宣传活动。 该相机将在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）三个波段工作，并将提供测量线性偏振的能力。 根据目前的计划，在未来一年内，望远镜表面的外两个环，覆盖直径在32米和50米之间的区域，将重新铺设表面，并及时进行主动控制，以便部署TolTEC。计划进行四次大视场遗留调查：（1）云-核遗留调查将探讨有关恒星初始质量函数的问题;（2）云-场-丝遗留调查将以赫歇尔空间望远镜最近关于丝在星星形成中的重要性和磁场作用的发现为基础;（3）对恒星形成星系的超深巡天将是对红移2-10的亮红外星系群的一次模糊有限巡天;大尺度结构巡天将利用Sunyeav Zel'dovich效应研究高红移下星系团的形成和动力学。
