NGC 3379 planetary nebulae radial velocities

We present the results of a radial velocity survey of planetary nebulae (PNs) in the normal elliptical galaxy NGC 3379 performed with the Kitt Peak 4m telescope and the NESSIE...我们呈现了利用基特峰4米望远镜与NESSIE，对正常椭圆星系NGC 3379内的行星状星云（planetary nebulae，PNs）开展视向速度巡天所得到的结果。
