摘要:

UKIDSS银河平面巡天(英语:Galactic Plane Survey)是由UKIDSS联合体进行的五个近红外公共遗产巡天之一,使用英国红外望远镜上的宽视场相机。它是测量1868 sq.deg.。在银河系纬度-5<b<5的北银河系平面和赤道银河系平面在J,H和K过滤器和a ~200平方度。在这三种滤光片和2.12 μ m(1-0)H_2滤光片中测量了Taurus-Auriga-Perseus分子云复合体的面积。它将提供约20亿来源的数据。在这里,我们描述了数据集的属性,并提供了一个用户的指南,其利用。我们还介绍了DR 2和科学验证计划的简要演示科学结果。这些结果说明了如何经常将全球定位系统数据与其他波段的数据相结合,以产生科学结果。示范科学包括以下研究:(一)恒星形成区G28.983-0.603,与斯皮策-GLIMPSE数据交叉匹配以确定YSO;(二)M17星云;(三)rho Ophiuchi暗云中的H_2发射;(四)银河系中心的X射线源;(五)回避区的外部星系;(六)IPHAS-GPS光学-红外分光光度分光光度分型。(节略)。

英文摘要:

The UKIDSS Galactic Plane Survey (GPS) is one of the five near infrared Public Legacy Surveys that are being undertaken by the UKIDSS consortium, using the Wide Field Camera on the United Kingdom Infrared Telescope. It is surveying 1868 sq.deg. of the northern and equatorial Galactic plane at Galactic latitudes -5<b<5 in the J, H and K filters and a ~200 sq.deg. area of the Taurus-Auriga-Perseus molecular cloud complex in these three filters and the 2.12 um (1-0) H_2 filter. It will provide data on ~2 billion sources. Here we describe the properties of the dataset and provide a user's guide for its exploitation. We also present brief Demonstration Science results from DR2 and from the Science Verification programme. These results illustrate how GPS data will frequently be combined with data taken in other wavebands to produce scientific results. The Demonstration Science includes studies of: (i) the star formation region G28.983-0.603, cross matching with Spitzer-GLIMPSE data to identify YSOs; (ii) the M17 nebula; (iii) H_2 emission in the rho Ophiuchi dark cloud; (iv) X-ray sources in the Galactic Centre; (v) external galaxies in the Zone of Avoidance; (vi) IPHAS-GPS optical-infrared spectrophotometric typing. (abridged).
