Dynamical Gravitational Coupling as a Modified Theory of General Relativity
Felix Finster, Christian Röken
A modified theory of general relativity is proposed, where the gravitational constant is replaced by a dynamical variable in space-time. The dynamics of the gravitational coupling…
Ionisation as indicator for cosmic ray acceleration
Florian Schuppan, Christian Röken, Natalie Fedrau +1
Astrospheres and wind bubbles of massive stars are believed to be sources of cosmic rays with energies TeV. These particles are not directly detectable, but their im…
On the Nature of Black Holes in Loop Quantum Gravity
Christian Röken
A genuine notion of black holes can only be obtained in the fundamental framework of quantum gravity resolving the curvature singularities and giving an account of the statistical…
First-order quantum-gravitational correction to Friedmannian cosmology from covariant, holomorphic spinfoam cosmology
Christian Röken
The first-order loop quantum gravity correction of the simplest, classical general-relativistic Friedmann Hamiltonian constraint, emerging from a holomorphic spinfoam cosmological…
