The Gravitational Waves observation by LIGO provided information about the physics in the extreme gravity of coalescing binary black holes. The LIGO/Virgo collaboration verified that this observation is consistent with General Relativity, constraining the presence of other possible parameters from the signal. However, expanding the analysis to a larger class of parameters, information can be drawn on non-standard physics mechanism that would be associated with the generation and propagation of gravitational waves, including the activation of scalar fields, gravitational leakage into large extra dimensions, the variability of Newton's constant, the speed of gravity, a modified dispersion relation, gravitational Lorentz violation and the strong equivalence principle.

The purpose of this workshop is to discuss the generation and propagation of Gravitational Waves from modified gravity theories giving emphasis on the Gravitational Waves from “dirty” black holes resulting from the interaction between black holes and scalar fields and also from cosmological scalar fields.

The Workshop will take place in a Conference Room in the Building Averof of the School of Architecture in the Central Campus of National Technical University of Athens which is located at Patission Street in central Athens (see the map). Note that the entrance to the NTUA Campus is from Stournari Street. The Workshop is sponsored by the National Technical University of Athens, the University of Tuebingen, the University of Nottingham and COST (European Cooperation in Science and Technology).
