Radio astronomy is a vital branch of astrophysical research that explores the properties of celestial objects such as galaxies, stars, the interstellar medium, compact objects, and black holes by analyzing radio waves from the universe. It helps us understand critical issues like cosmic evolution, galaxy formation, stellar life cycles, and the nature of dark matter and dark energy. The Department of Astronomy at Tsinghua University focuses on several key areas in radio astronomy: the ISM (interstellar medium) evolution and star formation, pulsars and fast radio bursts (FRBs), the development of novel concepts for large-field-of-view detectors of the dynamic universe, such as the "Cosmic Antennae" (phase-field telescopes, distributed antenna arrays, etc.), and various radio transients. These efforts leverage advanced domestic and international facilities, including “China Sky Eye” FAST, ALMA, CHIME, JWST, GBT, and the Delingha millimeter telescope. The department actively engages in international collaborations, leading and participating in major surveys such as the FAST key programs "Commensal Radio Astronomy FasT Survey (CRAFTS)" and "Fast Radio Burst Survey". Additionally, Tsinghua's astronomy team is committed to innovation in radio astronomy technology, collaborating with leading computational and AI institutions to develop next-generation AI-driven detection and research equipment and techniques.
