New Insights into High-Energy Astrophysics, Galaxies, and Cosmology: Celebrating the 10th Anniversary of Re-establishment Department Astronomy at Xiamen University (2012-2022)

The Department of Astronomy at Xiamen University, one of the earliest in modern Chinese history, was founded by Prof. Ching-Sung Yu in 1927. However, the department was suspended after Dr. Yu became the Director of the Astronomical Research Institute at Academia Sinica in 1929. In 2000, after Prof. Ju-fu Lu joined Xiamen University, the astronomy program began to flourish. His efforts attracted a strong team of researchers, leading to the official re-establishment of the Department of Astronomy in 2012. Today, the department's primary research areas include compact objects and high-energy astrophysics, galaxy formation and evolution, and cosmology. This Special Issue reprint provides a comprehensive overview of significant advancements and ongoing research within our department, inspiring future discoveries in the field of astronomy, and celebrating the 10th anniversary of the re-establishment of the Department of Astronomy.
