THCA Professor publishes a review paper in ARA&A

On August 18, 2017, a review paper entitled Ultraluminous X-ray Sources was published in this year’s Annual Review of Astronomy and Astrophysics, written by THCA Professor Hua Feng (second author), in collaboration with Philip Kaaret (first author), and Tim Roberts. The paper reviews the observational facts of a special kind of X-ray sources in the sky, so-called ultra-luminous X-ray sources (ULXs), and how theoretical models and numerical simulations can explain the data. The link between the studies of ULXs, the early universe, and the detection of gravitational waves is also discussed. Prof. Feng’s major interests are 1) to understand the physics around compact objects, including ULXs and 2) to develop novel instrumentation for future X-ray astronomy.


The Annual Review of Astronomy and Astrophysics is a peer reviewed journal published by the nonprofit publisher Annual Reviews. According to the Journal Citation Reports, the impact factor of ARA&A is 30.7 in 2016, ranked 1st out of 63 Astronomy and Astrophysics journals. So far, only four other astrophysicists based in mainland China have published papers in this journal.
