Westerbork HALOGAS调查:现状和早期结果
The Westerbork HALOGAS Survey: Status and Early Results
摘要:
我们目前正在进行的氢吸积LOCAL GALAXIES(HALOGAS)调查,这是与韦斯特博克合成射电望远镜(WSRT)进行的早期结果。HALOGAS调查的目的是通过对中性氢21厘米谱线发射的敏感观测,探测附近螺旋中的冷气吸积过程并确定其特征。在这方面的贡献,我们提出了一个正在进行的几个HALOGAS目标的分析概述。
英文摘要:
We present early results from the ongoing Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) Survey, which is being performed with the Westerbork Synthesis Radio Telescope (WSRT). The HALOGAS Survey aims to detect and characterize the cold gas accretion process in nearby spirals, through sensitive observations of neutral hydrogen (HI) 21-cm line emission. In this contribution, we present an overview of ongoing analyses of several HALOGAS targets.
