Strong gravitational lensing. A foreground galaxy stretches the galaxies behind it into tangential arcs and splits each into multiple images — a bright arc outside the Einstein radius, a faint counter-image within it — which close into a ring at alignment.

About this edition
The meetings provide a high-level platform for exchange between East and West in relativistic astrophysics and the related theory, experiment and observation. Organised jointly by China and Italy since 2009, they alternate between the two.
Registration on 1 November; sessions 2–4 November; departure 5 November
Organisers
- Ningbo University
- ICRANet — International Center for Relativistic Astrophysics Network
- Institute of Fundamental Physics and Quantum Technology, Ningbo University
Scientific Topics
The meeting covers relativistic astrophysics, with emphasis on but not limited to the following areas.
- Late stages of stellar evolution and explosive processes
- Physics of compact objects: neutron stars, black holes
- Gamma-ray bursts and their high-energy emission mechanisms
- X-ray and gamma-ray astrophysics
- Gravitational waves and precision tests of general relativity
- Nuclear astrophysics and the equation of state of dense matter
- Accretion processes and jet physics
- Related observational and theoretical advances in high-energy astrophysics
