Abstract
Maps have been made of the 2-centimeter brightness distribution of M17, Cassiopeia-A, Taurus-A, and Orion nebula with a resolution of 2.3 minutes of arc, revealing several newly resolved features. M17 is a double thermal source. Some structure appears in Cassiopeia-A, including a suggestion of a ring shape. Taurus-A exhibits a brightness map similar to that obtained in earlier low-frequency results. The central part of Orion nebula is circularly symmetric to a high degree of accuracy.
摘要
已经制作了 M17、仙后座 A、金牛座 A 和猎户座星云的 2 厘米亮度分布的地图，分辨率为 2.3 角分，揭示了几个新解析的特征。M17 是一个双热源。仙后座 A 中出现了一些结构，包括一个环形的暗示。金牛座 A 显示出与早期低频结果相似的亮度图。猎户座星云的中心部分具有高度精确的圆形对称性。
