Workshop on Collapsing Objects

21-24 October 2013, Fudan University (Shanghai, China)

During the gravitational collapse of a massive star, matter can reach extreme conditions, which are impossible to create in any laboratory on the Earth. In those cases in which nothing can stop the collapse, General Relativity predicts the formation of a space-time singularity, where predictability is lost and standard physics breaks down. The study of collapsing objects is a fascinating area of research and can shed light on the behavior of matter at very high densities and of gravity in the strong field regime.


Main topics:

-Supernovae

-Gamma Ray Bursts

-Binary System Coalescences

-Detection of Electromagnetic Radiation, Neutrinos, and Gravitational Waves from Collapsing Objects

-Gravitational Collapse in General Relativity and in Alternative Theories of Gravity

-Cosmic Censorship Conjecture

-Exotic Compact Objects
