Collaborative Research: Science with LWA1

这是新墨西哥大学和弗吉尼亚理工大学合作运营长波阵列(LWA1)第一个站的奖项。LWA1于2011年4月完成，目前是一个运行中的无线电观测站，除了持续的调试和表征计划外，还进行第一次征求建议书所产生的观测。该仪器由256个双偏振偶极子组成，这些偶极子被数字化并组合成波束。LWA1有四个可独立控制的双极化光束，每个都有两个16 MHz带宽的窗口，可以独立地调谐到10 MHz到88 MHz之间的任何频率。LWA1为银河系科学、脉冲星科学、太阳和行星科学、空间气象、宇宙学和搜索天体物理瞬变提供了独特的新功能。LWA1的结果将探测到或严格限制地球50秒内热木星的存在。LWA1将在频率和时间上提供高分辨率，以研究太阳爆发、蟹状脉冲星的巨大脉冲和4：1频率范围内的脉冲星等现象，其中包括鲜为人知的周转和陡峭光谱制度。再电离时代将通过一个由美国国家科学基金会资助的名为LEDA的项目来探索。在更广泛的影响领域，LWA1将培养未来仪器所需的工程人才，如再电离阵列的氢纪元(HERA)，将增加拉美裔对天文学的参与，并将为K-12学生直接参与观测提供机会，而不影响其主要科学任务。LWA1是大学开发的工具，学生和博士后已经并应该继续发挥开发人员和用户的重要作用。

This is a collaborative award to the University of New Mexico and Virginia Tech to operate the first station of the Long Wavelength Array (LWA1). LWA1 was completed in April 2011 and is currently an operating radio observatory, performing observations resulting from its first call for proposals in addition to a continuing program of commissioning and characterization. The instrument consists of 256 dual-polarization dipoles, which are digitized and combined into beams. Four independently-steerable dual-polarization beams are available, each with two windows of 16 MHz bandwidth that can be independently tuned to any frequency between 10 MHz and 88 MHz.LWA1 provides unique new capabilities for Galactic science, pulsar science, solar and planetary science, space weather, cosmology, and searches for astrophysical transients. Results from the LWA1 will detect or severely constrain the presence of hot Jupiters within 50 parsecs of Earth. The LWA1 will provide high resolution in frequency and in time to examine phenomena such as solar bursts, giant pulses from the Crab Pulsar, and pulsars over a 4:1 frequency range that includes the poorly-understood turnover and steep-spectrum regimes. The Epoch of Reionization will be explored via an NSF-supported project called LEDA. In the area of broader impacts, LWA1 will develop engineering talent required for future instruments such as the Hydrogen Epoch of Reionization Array (HERA), will increase the participation of Hispanics in astronomy, and will provide opportunities for the direct involvement of K-12 students in observing with no impact on its primary science mission. LWA1 is a university-developed instrument in which students and post-docs have played, and should continue to play, an essential role as developers and users.
