SIGNALS: Unveiling Star-Forming Regions in Nearby Galaxies

研究人员试图了解恒星如何在星系中形成，它们的出生地如何影响它们的性质，以及多代恒星如何改变星系。恒星通过将新元素返回星际气体来影响它们的环境。这些新的元素然后再循环形成新的恒星。恒星在各种各样的环境中形成。它们可能是不同的星系，不同的地点。结果是每个星星都有自己的故事。通过研究50，000个恒星活跃形成的区域，科学家们将了解是什么触发了它们的形成，恒星形成的效率如何，以及每一代恒星如何转变周围的气体。这也将有助于研究人员了解大爆炸以来整个宇宙的恒星形成历史。该项目由一名来自加拿大第一民族、居住在夏威夷的妇女领导，由70名研究人员组成，其中妇女占40%以上。预计将对夏威夷当地社区产生积极影响。该团队将与全州的STEM项目莫纳克亚学者合作，为他们的学生开发一个研讨会。莫纳克亚学者为夏威夷公立高中学生提供莫纳克亚天文台的望远镜时间。大多数学生是代表性不足的少数民族，包括女孩，夏威夷土著人和传统上服务不足的学生。研讨会将教授学生适用于他们的研究的新技能，鼓励他们的能力的信心。利用在加拿大-法国-夏威夷望远镜上进行的SIGNALS调查的数据，调查人员将研究50，000个空间分辨的恒星形成区域的光谱，以及其中的恒星，平均空间分辨率为20 pc。来自UV、IR、HI和CO的次级数据将使研究小组能够正确测量当地的环境特性，例如每个区域周围的恒星和气体密度。该团队将使用定制的建模技术和全球研究不同环境中的恒星种群来分析数据。他们的目标是首先测量环境对星星形成过程的影响。其次，将恒星再循环过程与周围恒星形成区域内的局部化学富集和动力学联系起来。他们的第三个目标是测量星星形成率作为测量指标的函数，因此，这些指标可以准确地应用于更遥远的星系的研究。该项目由天文学部和刺激竞争性研究的既定计划（EPSCoR）共同资助该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的评估被认为值得支持。影响审查标准。

The investigators seek to understand how stars form in galaxies, how their birthplace affects their properties, and how multiple generations of stars transform galaxies. Stars affect their environment by returning new elements to the interstellar gas. These new elements are then recycled to form new stars. Stars form in a wide variety of environments. These can be different galaxy to galaxy, location to location. The result is that each star has its own story. By studying 50,000 regions where stars actively form, scientists will understand what triggers their formation, how efficiently stars form, and how each generation transforms the gas around them. This will also help researchers to understand the star-formation history of the whole Universe since the Big-Bang. This project is led by a woman from the First Nations of Canada based in Hawaii and is composed of a group of 70 researchers including more than 40% of woman. Positive impacts are expected on the local community in Hawaii. The team will collaborate with a statewide STEM program, Mauna Kea Scholars, to develop a workshop for their students. Mauna Kea Scholars provides telescope time on the Mauna Kea Observatories for Hawaii public high schools students. Most of the students are underrepresented minorities, including girls, Native Hawaiians, and traditionally underserved students. The workshop will teach the students new skills applicable within their research, encouraging confidence in their abilities. Using data from the SIGNALS survey conducted at the Canada-France-Hawaii Telescope with a Fourier Transform Spectrograph, the investigators will study the spectra of 50,000 spatially resolved star-forming regions, and the stars within, at a mean spatial resolution of 20 pc. Secondary data from UV, IR, HI and CO will allow the team to properly measure the local environmental properties such as the density of stars and gas around each region. The team will analyze the data using a custom-tailored modeling technique and a global study stellar populations in different environments. Their goals are to first measure the impact of the environment on the star formation process. Second, link the stellar recycling processes to the local chemical enrichment and dynamics within the surrounding star-forming regions. Their third goal is measuring the star formation rate as a function of the measured indicators, so these indicators can be accurately applied to studies of more distant galaxies.This project is jointly funded by Astronomy Division and the Established Program to Stimulate Competitive Research (EPSCoR).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
