There is an impressive income of observational data for compact
objects, which include black holes, neutron stars, white dwarfs.
These compact objects are generated through the accretion of
matter. Recently, observations of LIGO/Virgo proved the existence
of binary black holes mergers through detection of gravitational
waves, and additionally the Event Horizon Telescope revealed the
existence of supermassive black holes in centre of galaxy M87 and
Milky Way. Future observational data, will permit to probe
additional gravitational parameters, eventually checking the
validity of no-hair theorems, star trajectories beyond precession,
novel observations of exceptional objects, including binary
pulsars in a strong gravity field. One could possibly entertain
the discovery of novel compact objects theoretically disfavoured
from GR such as hairy black holes or wormholes, for example
distinguishing a wormhole throat versus an event horizon. A
fruitful way of testing the behaviour of compact objects is to
explore the features of modified gravity theories.
The purpose of this workshop is to discuss the generation of
compact objects by the interaction of matter to black holes in
general modified gravity theories like scalar-tensor theories,
high curvature theories and theories with high derivatives.
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 Paris-Saclay
COST (European Cooperation in Science and Technology).
