摘要:

我们提出了PPAK积分场光谱(IFS)附近的Galerkin调查:PINGS,一个2维光谱镶嵌的17个附近的盘星系在光学波长范围内。该项目是首次尝试获得附近宇宙中星系整个表面的连续覆盖光谱。最终的数据集包括50000多个单独的光谱,总共覆盖了近80弧分的观测区域^[2]。在本文中,我们描述了主要的天体物理问题要解决的PINGS项目,我们提出的星系样本和解释的观测策略,数据处理过程和所有的不确定性。此外,我们给出了一些从PINGS样本的第一次分析中提取的科学亮点。

英文摘要:

We present the PPAK Integral Field Spectroscopy (IFS) Nearby Galaxies Survey: PINGS, a 2-dimensional spectroscopic mosaicking of 17 nearby disk galaxies in the optical wavelength range. This project represents the first attempt to obtain continuous coverage spectra of the whole surface of a galaxy in the nearby universe. The final data set comprises more than 50000 individual spectra, covering in total an observed area of nearly 80 arcmin^2. In this paper we describe the main astrophysical issues to be addressed by the PINGS project, we present the galaxy sample and explain the observing strategy, the data reduction process and all uncertainties involved. Additionally, we give some scientific highlights extracted from the first analysis of the PINGS sample.
