Collaborative Research: MAGPIS: A Multi-Array Galactic Plane Imaging Survey

AST0507663在超大型阵列20周年之际，对厘米波长的银河系平面进行的最好的测量是在20厘米和11厘米的5-10角分钟分辨率的埃菲尔斯伯格测量。两年前，David Helfand博士和Robert Becker博士开始了一项计划，利用MAGPIS(多阵列银河平面成像测量)将银河系图像的分辨率和灵敏度提高两个数量级。他们刚刚完成了从经度L=5到L=32的平面成像，分辨率为5角秒，动态范围为1000：1，点源灵敏度为“1mJy”。这些图像可在http://third.ucllnl.org/gps，网站上公开获取，并将用于广泛的应用，从结合正在进行的斯皮策平面测量对银河系恒星形成进行全面普查，到发现银河系最年轻的超新星残骸，再到计算合并中子星产生的LIGO信号的预期速率。哥伦比亚大学的赫尔方德博士和加州大学戴维斯分校的罗伯特·贝克尔博士获得的这一合作项目奖将用于继续创建这张银河系平面的最终图像，并支持其公开分发，以及将调查结果用于各种科学计划，因为通过银河系在射电、中红外和X射线波长的新视角已经成为可能。在这个项目中创建的数据产品都是公开的，并将在未来几十年内用于银河系研究。为访问这些数据而创建的工具也很可能具有广泛的适用性。该项目还将提供许多机会，将研究生和本科生教育与研究工作结合起来。这些研究人员已经建议与19名以上的博士物理学家和天文学家约会，还有更多的人将参与到这个项目中来。过去的八名博士中有六名是女性，我们将继续努力纠正女性和少数族裔在我们学科中代表性不足的问题。***

AST 0507663BeckerOn the 20th anniversary of the Very Large Array, the best available survey of the Galactic Plane at centimeter wavelengths were the 5-10-arcminute resolution Effelsberg surveys at 20 and 11 cm. Two years ago, Drs David Helfand and Robert Becker began a program to improve the resolution and sensitivity of the image of the Galaxy by two orders of magnitude with MAGPIS, the Multi-Array Galactic Plane Imaging Survey. They have just completed imaging the Plane from longitude l = 5 to l = 32 with a resolution of 5 arcseconds, a dynamic range of 1000:1, and a point-source sensitivity of " 1 mJy. These images are publicly available at the website http://third.ucllnl.org/gps, and will find use in a wide variety of applications ranging from the construction of a complete census of the Galaxy's star formation in conjunction with the ongoing Spitzer Plane surveys, to the discovery of the youngest supernova remnants in the Galaxy, to calculation of the expected rate of LIGO signals from merging neutron stars. This collaborative project award for Dr. Helfand at Columbia University and Dr. Robert Becker at the University of California at Davis will be used to continue the creation of this definitive image of the Galactic Plane and to support its public distribution, as well as to use the survey results in a variety of science programs now becoming possible as a consequence of new views through the Galaxy at radio, mid-IR, and X-ray wavelengths.The data products created in this project are all publicly available, and will find use in Galactic studies for decades to come. The tools created for accessing these data may well also find wide applicability. The project will also provide many opportunities for integrating graduate and undergraduate education with the research effort. These researchers have advised to date more than nineteen PhD physicists and astronomers, and several more will become involved with this project. Six of the last eight PhDs are women, and there will be a continuing effort to focus on redressing the under-representation of women and minorities in our discipline. ***
