Fri, 2022-06-17A team of astronomers, led by Professor Linhua Jiang at the Kavli Institute for Astronomy and Astrophysics and School of Physics at Peking University, has revealed that distant quasars or galactic nuclei with actively growing supermassive black holes made a negligible contribution of ionizing photons to cosmic reionization 13 billion years ago. This finding settles a long-standing issue about the quasar contribution to cosmic reionization, and suggests that galaxies are the major energy sources. The result was recently published as an article in Nature Astronomy on June 16, 2022.

Fri, 2022-05-13Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes. This effort involved three scientists affiliated with Peking University, including the Director and University Chair Professor Luis C. Ho and Assistant Professor Lijing Shao from the Kavli Institute for Astronomy and Astrophysics, and Assistant Professor He Sun from the College of Future Technology.
