  • Decorative imageThis is a school on theories and observations of astrophysical black-hole systems. Black holes make themselves detectable in electromagnetic waves by forming accretion disks in their surroundings and sometimes producing outflow jets. Observations across the whole electromagnetic spectrum on X-ray binaries and Active Galactic Nuclei (AGN) have revealed many fascinating phenomena related to the strong gravity and fast spin of the central black holes, to the physics of accretion flows, and to the formation and collimation of jets. Theoretical efforts in past decades have also led to deeper understanding of all these subjects. We are very pleased to hold this school on ‘Accretion and Emission of Accreting Black Holes’ and cordially invite all interested students and colleagues to ...Read More
  • Decorative image【Speaker】Chung-Pei Ma, Professor of Astronomy and Physics, UC Berkeley 【Abstract】For over three decades, the giant elliptical galaxy Messier 87 in the Virgo Cluster has hosted the most massive known black hole in the local universe. New observational data have substantially expanded dynamical measurements of black hole masses at the centers of nearby galaxies. I will describe recent progress in discovering black holes up to twenty billion solar masses in ongoing surveys of massive elliptical galaxies. I will discuss the implications of this new population of ultra-massive black holes, including its impact on our understanding of the symbiotic relationships between black holes and galaxies, and on the gravitational-wave signals from merging black hole binaries targeted by ongoing pulsar ti...Read More
  • Decorative image NCTS Annual Theory Meeting is organized by the National Center for Theoretical Science. The main purpose of this series of annual meetings is to bring together leading physicists to report on their latest research results and to speak on prospects for the future as well as to interact with the physicists especially young researchers in Taiwan. There is one meeting on high energy physics (particles, cosmology and string) and one on condensed matter physics held annually. Condensed matter physics is extremely fascinating, highly dynamic and also fundamental to modern technologies. Therefore, the NCTS Annual Theory Meeting in Condensed Matter Physics this year will focus on the topological and 2D materials. Organizing Committee: Feng-Chuan Chuang (co-chair), National Sun-Yet-Sen ...Read More
