Ground-state OH masers in W3(OH) study

We present VLBA observations of the ground-state hydroxyl masers in W3(OH) at 0.02km/s spectral resolution. Over 250 masers are detected, including 56 Zeeman pairs. Line shapes...本研究报道了针对天体W3(OH)中基态羟基脉泽（ground-state hydroxyl masers）的甚长基线阵列（Very Long Baseline Array，VLBA）观测，观测采用0.02km/s的光谱分辨率。此次观测共探测到超过250个脉泽源，其中包含56个塞曼对（Zeeman pairs）。谱线形态……
