越来越多的证据表明，在银河系中心观测到的一系列现象中，磁场是很重要的。我们在这里报告了Zeeman对环核盘（CND；内半径约1.7 pc）中致密分子气体磁场的测量，使用1667 MHz OH吸收对银河系中心（Sgr A）的连续射电源。这些观测结果的分辨率为3″×4″（在8 kpc时为0.15 pc）
There is mounting evidence that suggests magnetic fields are important in a range of phenomena observed in the Galactic center. We report here Zeeman measurements of the magnetic field in the dense molecular gas in the circumnuclear disk (CND; inner radius ∼1.7 pc) using the 1667 MHz OH absorption against the continuum radio source at the Galactic center (Sgr A). These observations with a resolution of 3″×4″ (∼0.15 pc at 8 kpc) were made with the Very Large Array
