Introduction to black holes
The articles below give an introduction to the physics behind black holes and the different working groups of this COST Action. The concept of black holes allows them to appear with various masses from supermassive (M ~ 106 - 109 Msol) to quantum scales (M ~ 10-19 Msol). The existence of stellar and supermassive black holes is supported by very convincing evidence whereas quantum black holes remain to be discovered (e.g. by the LHC).
