类星体对于天体测量是必不可少的,因为它们离太阳很远,所以在空间上是静止的。欧洲航天局(欧空局)的盖亚天体测量卫星正在以前所未有的精度扫描整个天空,精度可达几微秒。然而,盖亚的双视场观测策略可能会在盖亚星表中引入视差偏差。由于类星体没有明显的视差,它是探测这种偏差的完美自然对象。更重要的是,类星体可以用来为盖亚使命构建一个光波段的天体参考系。在这篇文章中,我们整理了一个已知的类星体列表,已经在文献中发表。最终的汇编(命名为Gaia使命已知类星体目录,KQCG)包含1842076个天体,其中797632个天体在交叉识别后在Gaia DR 1中被发现。如果可能的话,还提供了物体的红移、颜色信息和位置不确定性。这个目录对盖亚使命将非常有用。
Quasars are essential for astrometry in the sense that they are spatially stationary because of their large distance from the Sun. The European Space Agency (ESA) astrometric satellite Gaia is scanning the whole sky with unprecedented accuracy up to the level of a few μas. However, Gaia’s two-fields-of-view-observation strategy may introduce a parallax bias in the Gaia catalog. Since it presents no significant parallax, a quasar is the perfect natural object to detect such bias. More importantly, quasars can be used to construct a celestial reference frame in the optical wavelengths for the Gaia mission. In this paper, we compile a list of known quasars that have been published in the literatures. The final compilation (designated as Known Quasars Catalog for Gaia mission, KQCG) contains 1 842 076 objects, among which 797 632 objects are found in Gaia DR1 after cross-identifications. Redshift, color information and position uncertainties of the objects are also provided if available. This catalog will be very useful for the Gaia mission.
