Description

Asia-Pacific School and Workshop on Gravitation and Cosmology 2022

Mar 19~22, 2022

General relativity has set a formidable benchmark for studying the characteristics of spacetime and its connections to the material world. The remarkable findings in cosmology and astrophysics, such as the expansion of the Universe, gravitational lensing, black holes, and gravitational waves not only change the conventional wisdom about the Mother Nature, but also pave the way for exploring the foundation of physics. However, new discoveries in recent years, including the Hubble tension, the enigmas regarding dark energy and dark matter, have requested further intellectual dedication and investigation to respond such profound challenges.

We have had a series of annual school/workshop on these topics since 2007 in Taidong, Taiwan, with the most recent version being held at Center for Theoretical Physics of the Universe, Institute for Basic Science, Daejeon, Korea, Feb 2020. Unfortunately the school and workshop in 2021 was cancelled  due to Covid-19. APSW 2022 will be a virtual meeting.

The school/workshop aims to promote understanding in frontier issues in gravitation and cosmology, to put forth a new idea, and to introduce and propose challenging problems to young physicists. 

This program consists of two parts. In the school, invited lecturers deliver a series of lectures from introductory to research level to help students and junior researchers to grasp the essence of the cutting-edge developments. In the workshop, participants are expected to give presentations on the recent developments in gravitation and cosmology and are encouraged to have intensive discussions and establish collaborations.

The topics to be covered by the school/workshop include

  • Gravitational waves
  • Numerical relativity
  • Black hole physics
  • Cosmic microwave background
  • Inflationary universe
  • Dark matter and dark energy
  • Quantum gravity
