Galactic Center 6 and 20cm survey

We have used the VLA to survey 10 fields at 20 cm (1658MHz) and 11 fields at 6 cm (5GHz) that are between 7' and 137' from SgrA. Our objective was to identify extragalactic...我们利用甚大天线阵（Very Large Array，VLA）对10个天区开展了20厘米（1658MHz）波段的射电巡天观测，并对11个天区完成了6厘米（5GHz）波段的射电巡天观测，所有上述天区与人马座A（Sgr A，SgrA）的角距离均介于7角分至137角分之间。本研究的目标为识别河外（extragalactic...）。
