摘要:

英国红外望远镜(UKIRT)的铁$^+$宽视场红外巡天(UWIFE)是对银河系第一象限(7 $^{\circ}$ <1 < 62 $^{\circ}$ ; |b| < 1.5 $^{\circ}$)的180度$^2$成像巡天,使用以[Fe II] 1.644 μm发射线为中心的窄带滤光片。[Fe II] 1.644 μm的发射是致密的激波激发气体的良好示踪剂,该调查将探测恒星周围的暴力环境:恒星形成区,演化的恒星和超新星遗迹等。UWIFE调查旨在补充现有的UKIRT H2广域红外调查(UWISH 2; Froebrich等人,2011)。该调查还将补充现有的宽带调查。观测图像的点源标称5σ探测限为18.7 mag,中值视宁度为0.83”。对于扩展源,我们估计表面亮度极限为8.1 × 10 $^{-20}$ W m $^{-2}$ arcsec $^{-2}$。在本文中,我们提出了这项调查的概述和初步结果。

英文摘要:

The United Kingdom Infrared Telescope (UKIRT) Widefield Infrared Survey for Fe$^+$ (UWIFE) is a 180 deg$^2$ imaging survey of the first Galactic quadrant (7$^{\circ}$ < l < 62$^{\circ}$; |b| < 1.5$^{\circ}$) using a narrow-band filter centered on the [Fe II] 1.644 μm emission line. The [Fe II] 1.644 μm emission is a good tracer of dense, shock-excited gas, and the survey will probe violent environments around stars: star-forming regions, evolved stars, and supernova remnants, among others. The UWIFE survey is designed to complement the existing UKIRT Widefield Infrared Survey for H2 (UWISH2; Froebrich et al. 2011). The survey will also complement existing broad-band surveys. The observed images have a nominal 5σ detection limit of 18.7 mag for point sources, with the median seeing of 0.83". For extended sources, we estimate surface brightness limit of 8.1 x 10$^{-20}$ W m$^{-2}$ arcsec$^{-2}$ . In this paper, we present the overview and preliminary results of this survey.
