Swift/UVOT observations of 12 nearby SN-Ia

We compare early ultraviolet (UV) observations of Type Ia supernovae (SNe Ia) with theoretical predictions for the brightness of the shock associated with the collision between...我们将Ia型超新星（Type Ia supernovae，SNe Ia）的早期紫外线（ultraviolet，UV）观测结果，与碰撞过程所关联的激波亮度的理论预测进行对比。
