The UV and X-ray Astronomy (UVXA) Research Group at Purple Mountain Observatory, Chinese Academy of Sciences, was established in 2017. Based on the high-resolution spectroscopy studies in High-energy astrophysics, we aim to investigate the frontiers of UV and X-ray Astronomy both in science and technology.
Our research interests are mainly focused on 1) the hot diffuse gas in/surrounding galaxies, 2) the nuclear regions harboring the supermassive black holes, 3) the warm absorbers, 4) the feedback from young stars/stellar clusters, 5) the multi-phase plasmas in galaxies of clusters, 6) the X-ray binaries and compact objects, and 7) the census of missing baryons. At present, we mainly take advantage of all available space/ground missions, such as Chandra, XMM-Newton, HST, and FAST, and the most updated atomic database (ATOMDB) to unveil the physical properties of those hot/warm/cold diffuse gas in different regions.
In addition, we are interested in the technologies in UV and X-ray Astronomy. We devote ourselves to develop the new space missions to explore the far-UV emission mapping of the diffuse universe. Currently, we are working on the key technologies for the small UV explorer CAFE (Census of WHIM, Accretion and Feedback Explorer). We also propose LyRIC (Lyman UV Radiation from ISM and CGM), the large independent payload on our space station. Besides, we join our science efforts to the future missions such as the future space observatories XRISM(2023), CSST(2023+), and Athena(2032+), and the developing project such as HUBs.
