Collaborative Research: CDS&E: New Image Resampling Techniques for the Mapping Nearby Galaxies at Apache Point Observatory in the NASA Sloan Atlas

对本宇宙中大量星系的观测使我们能够了解星系是如何通过恒星形成而成长的。恒星形成和气体与中央黑洞的相互作用都会对星系中恒星形成的速度产生正负反馈。该项目将开发一种新的分析工具，用于综合从地面和空间的许多不同天文台获得的数据。这些数据将被用来生成附近星系的统一目录，其中包括从紫外线到红外的各种波长的图像，以及从一些单独的星系获取的光谱。该星表将对研究星系增长的研究人员有价值。APO(漫画)的测绘附近星系的调查提供了从NASA斯隆地图集中挑选出来的10,000个附近星系的表面光谱。这些数据使得关于动力学、恒星形成历史、活动星系核等的广泛科学研究成为可能。这个新数据集最有成效的用途是将TIN与可用于这些星系的从紫外线到红外的多波长成像数据集结合使用。该项目将在所有这些波长和光谱范围内产生一致的位置采样图像，并将公开发布数据集。他们将开发一种更好的分析技术，将重新采样的负面影响降至最低。这项技术在天文学内外都有广泛的应用。利用这一技术的算法也将公开可用。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Observations of a large population of galaxies in the local universe allows us to learn about how galaxies grow through star formation. Both star formation and the interaction of gas with the central black hole can have positive and negative feedback on the rate at which stars form in galaxies. This project will develop a new analysis tool for combining data taken from many different observatories on the ground and in space. The data will be used to produce a uniform catalog of nearby galaxies with images in wavelengths from ultraviolet to infrared, as well as spectra taken from some individual galaxies. The catalog will be of value to researchers who study galaxy growth.The Mapping Nearby Galaxies at APO (MaNGA) survey is providing spectroscopy across the face of 10,000 nearby galaxies selected from the NASA Sloan Atlas. This data enables a broad range of science on dynamics, star formation histories, active galactic nuclei, and more. The most productive use of this new data set is to use tin conjunction with the multiwavelength imaging data sets available for these galaxies from the ultraviolet through to the infrared. The project will produce images consistently sampled in position across all of these wavelengths and within the spectra, and will publicly release the data set. They will develop a better analysis technique that minimizes the negative effects of resampling. The technique may have broad application inside and outside astronomy. An algorithm exploiting this technique will also be made publicly available.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.
