On the afternoon of November 26, Prof. Huang, Jiasheng, an astronomer from the National Astronomical Observatories of China, was invited to School of Physics and Technology，NNU to give a wonderful academic report on "Massive galaxy Evolution since z=2" at Xingjian building 437. Teachers, postgraduates and undergraduates participated in this seminar.
Prof. Huang, Jiasheng first pointed out that the most important epoch in galaxy evolution was at z=2~3 where both star formation rate density and AGN activities were in their peak stage. The star formation happened in most massive galaxies with very intensive burst known as Ultraluminous Infrared Galaxies (ULIRGs). Current galaxy formation theories fail to predict numbers of ULIRGs at this redshift and also have a hard time to propose a mechanism to quench this burst. In the report, Prof. Huang discussed in detail the ULIRG population at z~2 and their descendent counterparts, massive red galaxies at z~1. In addition, he tried to establish their evolution connection using the large samples in wide field, yet deep, surveys in both optical and IR bands.
Prof. Huang is the chief and executive director of Chinese Academy of Sciences South America Center (CASSACA) for Astronomy. He also introduced the CASSACA to the teachers and students in terms of the construction, observation base, planning of Science Park and its sustainable development. He also welcomed the scholars and students in Nanjing Normal University to visit there for academic exchange.
