This award will support construction, operation, and data management/distribution for the Zwicky Transient Facility (ZTF), a camera upgrade and renovation for the 48-inch Oschin Schmidt telescope on Mt Palomar. The telescope will conduct wide-area sky surveys with a goal of identifying new types of rare, rapidly varying astronomical sources at locations ranging from inside our own Solar System to significant fractions of the distance "across" the universe. Broader impacts of the work include hands-on training of students and early career scientists developing instrumentation for large area sky surveys. Expertise will be developed in STEM fields and will lead to skills important for NSF's major new project, the LSST. The ZTF will conduct an annual time-domain summer school open to students throughout the US, and will share the excitement of the Dynamic Sky with the public via an outreach program at the Palomar Observatory Visitors' Center. The facility will conduct a synoptic survey for high-cadence time-domain astronomy with the goal of identifying rare, fast-varying sources. These sources will include supernovae, exotic explosive transients, unusual stellar variables, compact binaries, active galactic nuclei, and asteroids. The ZTF survey will cover the entire Northern Sky, revisiting fields on timescales of a few hours and providing hundreds of visits per field each year. This shallow-wide-fast cadence is well suited to detecting fast transients and probing rapid variability. The single-visit depth of 20.4mag is well-matched to current spectrographs on 4-m class telescopes, while the final co-added images will provide wide sky coverage that is about two magnitudes deeper than that of the Sloan Digital Sky Survey. The new camera will have a 47 square degree field of view, larger than the original Palomar Sky Survey which was recorded on glass plates using this same telescope almost 60 years ago. The proposing team has substantial experience in this field, having run the similar but less powerful Palomar Transient Factory for a number of years previous to this. The project is leveraged by contributions from a number of partner institutions, including Caltech (lead), the Infrared Processing and Analysis Center (IPAC), Lawrence Berkeley Laboratory, the Weizmann Institute of Science (Israel), the Oskar Klein Centre (Sweden), DESY (High Energy Astronomy, Germany), Los Alamos National Laboratory, TANGO (Taiwan), the University of Wisconsin-Milwaukee, the Intra-University Centre for Astronomy and Astrophysics (India), and Pomona College.

该奖项将支持Zwicky Transient设施（ZTF）的施工，操作和数据管理/分发，这是48英寸Oschin Schmidt TeleScope MT Palomar上的相机升级和翻新。望远镜将进行广阔的天空调查，目的是在宇宙中识别从我们自己的太阳系内部到距离的显着分数的新型稀有，迅速变化的天文来源。这项工作的更广泛的影响包括对学生的动手培训和早期职业科学家开发大型天空调查的仪器。 专业知识将在STEM领域发展，并将导致对NSF的主要新项目LSST重要的技能。 ZTF将在美国的学生开设一所年度时间域暑期学校，并通过在Palomar天文台游客中心的宣传计划与公众分享动态天空的兴奋。 该设施将对高振动时间域天文学进行概要调查，目的是确定罕见的快速变化来源。这些来源将包括超新星，外来的爆炸性瞬变，异常的恒星变量，紧凑的二进制文件，活跃的银河核和小行星。 ZTF调查将覆盖整个北方天空，重新访问几个小时的时间尺度，并每年提供数百次访问。 这种浅宽的节奏非常适合检测快速瞬变和探测快速变化。在4-M类望远镜上的当前光谱仪匹配时，单访问深度为20.4mag，而最终的共同添加图像将提供宽阔的天空覆盖范围，比Sloan Digital Sky Survey更深约两个大小。 新相机将具有47平方英尺的视野，比原始的Palomar Sky调查大，该调查是在大约60年前使用同一望远镜在玻璃板上记录的。 提议的团队在此领域拥有丰富的经验，在此之前的许多年里，经营着相似但功能不佳的Palomar Transient工厂。 该项目由许多合作伙伴机构的贡献（包括加州大学（LEAD），红外加工和分析中心（IPAC），劳伦斯·伯克利实验室，韦兹曼科学学院（以色列），奥斯卡·克莱因中心（瑞典）（瑞典），德国高级能源天文学，美国阿拉姆·阿马姆·安马姆·安马姆·安马姆·安马姆·坦克（University the University the Universation），威斯康星州 - 米尔沃基，国内天文学和天体物理学中心（印度）和波莫纳学院。
