摘要:

本文给出了用国家伽利略望远镜获得的113个红移< 0.3的3CR射电源的光学核谱的均匀和92%完整的数据集。对于这些来源,我们可以获得关键的光谱光学诊断的均匀和不间断的覆盖。观测到的样本,包括强大的经典FR II射电星系和FR I,一起跨越四个数量级的射电光度,提供了一个广泛的代表性的射电星系的光谱特性。在这第一篇论文中,我们提出了一个图集的光谱,提供测量的诊断发射线的比率,并确定活跃的核宽线发射。这些数据将用于后续论文,以解决样品的光谱特性和多波长特性之间的联系。

英文摘要:

We present a homogeneous and 92 % complete dataset of optical nuclear spectra for the 113 3CR radio sources with redshifts < 0.3, obtained with the Telescopio Nazionale Galileo. For these sources we could obtain uniform and uninterrupted coverage of the key spectroscopic optical diagnostics. The observed sample, including powerful classical FR II radio-galaxies and FR I, together spanning four orders of magnitude in radio-luminosity, provides a broad representation of the spectroscopic properties of radio galaxies. In this first paper we present an atlas of the spectra obtained, provide measurements of the diagnostic emission line ratios, and identify active nuclei with broad line emission. These data will be used in follow-up papers to address the connection between the optical spectral characteristics and the multiwavelength properties of the sample.
