Project

Testing strong gravity via black holes (GA19-03950S)

There is now an increasing interest to test the theory of gravity at very large scales and in strong gravitational fields. The best laboratory to test strong gravity, there are a number of theories beyond Einstein'...

New Precision Tests of the Dark Sector (GA24-10780S)

Modern cosmology assumes that General Relativity (GR) correctly describes gravity at the scales of galaxies, clusters and the observable universe tantalising possibility is that these tensions are evidence that gravity on the scales...

Signatures of strong gravity in black hole accretion discs and in outflows (GA205/07/0052)

We propose to study signatures of strong gravity which can be recognized by methods of X-ray astronomy in galactic nuclei and compact binary stars. We concentrate ourselves on novel ways to determine the mass and angular momentum of...
