The redshift evolution of ULXs out to z~0.5

Ultraluminous X-ray sources (ULXs) are thought to be powerful X-ray binaries (XRBs) and may contribute significantly to the redshift-dependent X-ray emission from star-forming...超亮X射线源（Ultraluminous X-ray sources，ULXs）被普遍认为是高光度X射线双星（X-ray binaries，XRBs），且可能对恒星形成相关天体中依赖红移的X射线辐射做出显著贡献。
