银河系中心区基态OH脉泽分布

Ground-state OH maser distributions in the Galactic Centre region

Hai-Hua Qiao, Andrew J. Walsh, Zhi-Qiang Shen, Joanne R. Dawson

摘要:

用澳大利亚望远镜紧凑阵列观测了在南帕克斯大面积巡天中发现的基态OH脉泽,以获得高精度的位置($\sim$ 1\,arcsec)。根据OH脉泽的精确位置,我们将其分为演化恒星OH脉泽、恒星形成OH脉泽、超新星遗迹OH脉泽、行星状星云OH脉泽和未知OH脉泽。我们详细研究了银河系中心区域(介于$-5^{\circ}$到$+5^{\circ}$的银河系边缘和$-2^{\circ}$和$+2^{\circ}$的银河系纬度之间)演化的恒星和恒星形成OH脉泽位置,以了解它们的分布。

英文摘要:

Ground-state OH masers identified in the Southern Parkes Large-Area Survey in Hydroxyl were observed with the Australia Telescope Compact Array to obtain positions with high accuracy ($\sim$1\,arcsec). We classified these OH masers into evolved star OH maser sites, star formation OH maser sites, supernova remnant OH maser sites, planetary nebula OH maser sites and unknown maser sites using their accurate positions. Evolved star and star formation OH maser sites in the Galactic Centre region (between Galactic longitudes of $-5^{\circ}$ to $+5^{\circ}$ and Galactic latitudes of $-2^{\circ}$ and $+2^{\circ}$) were studied in detail to understand their distributions.
