ABSTRACT AST-9420159. Irvine, William M. The 14m radio telescope of the Five College Radio Astronomy Observatory (FCRAO) is owned and operated by the University of Massachusetts at Amherst. By operating the facility under the Five College Astronomy program, faculty and students at the University and 4 other nearby institutions (Smith College, Amherst College, Mount Holyoke College and Hampshire College) can utilize each other's facilities. The antenna is used primarily for interstellar spectroscopy in the 80-120 GHz band, although single-pixel receivers are also available for the 130-170 GHz and 35-50 GHz bands; a dual-channel 1mm receiver system is also available. This award will support education, technology development and research with the 14-meter radio telescope for a period of three years. Building on its success during the past three-year grant period, the 15-element focal plane array receiver and recentlycompleted autocorrelator spectrometer will be used in a wide variety of studies of objects ranging from the Solar system to the distant galaxies. Major observatory programs in this period will include an imaging survey of carbon monoxide emission from the first quadrant of the Galaxy, a systematic survey of the cores of several nearby molecular clouds, objects believed to be sites of imminent star formation, and a systematic, high-resolution study of molecular gas in the nearby Andromeda spiral galaxy. Work will also begin on a new generation of focal plane array receivers, intended to increase the mapping capabilities of the FCRAO antenna by an order of magnitude. ***

摘要 AST-9420159。 作者：William M. 五学院射电天文台（FCRAO）的14米射电望远镜由位于阿默斯特的马萨诸塞州大学拥有和运营。通过在五个学院天文学项目下运行该设施，大学和附近其他4个机构（史密斯学院、阿默斯特学院、霍利奥克山学院和汉普郡学院）的教师和学生可以利用彼此的设施。该天线主要用于80-120 GHz频段的星际光谱学，尽管单像素接收器也可用于130-170 GHz和35-50 GHz频段;也可使用双通道1 mm接收器系统。 该奖项将支持14米射电望远镜的教育，技术开发和研究，为期三年。在过去三年赠款期取得成功的基础上，15元件焦平面阵列接收器和最近完成的自相关分光计将用于对从太阳系到遥远星系的各种物体进行研究。这一时期的主要观测计划将包括对银河系第一象限的一氧化碳排放进行成像调查，对附近几个分子云的核心进行系统调查，这些分子云被认为是即将形成星星的天体，以及对附近仙女座螺旋星系的分子气体进行系统的高分辨率研究。还将开始研制新一代焦平面阵列接收器，目的是将FCRAO天线的测绘能力提高一个数量级。 ***
