Intermediate high-velocity clouds distances

We present optical spectra of 403 stars and quasi-stellar objects in order to obtain distance limits towards intermediate- and high-velocity clouds (IHVCs), including new...本研究报道了403颗恒星与类星体（quasi-stellar objects）的光学光谱，旨在获取朝向中等速度云和高速云（IHVCs）的距离限制，其中包含新增的……
