Secondary Gravitational Waves in Non-local Starobinsky inflation
Andrea Addazi, Alexey S. Koshelev, Shi Pi +1
We show how infinite derivative modifications of gravity impact on the stochastic background of Gravitational Waves from early Universe. The generic property of the ghost-free theo…
Apparent non-variable stars from the Kepler mission
E. Paunzen, F. Binder, A. Cyniburk +12
The analysis of non-variable stars is generally neglected in the literature. However, such objects are needed for many calibration processes and for testing pulsational models. The…
Non-perturbative quantum gravity denounces singular Black Holes
Alexey Koshelev, Anna Tokareva
Although General Relativity predicts the presence of a singularity inside of a Black Hole, it is not a complete theory of gravity. A real structure of a Black Hole interior near an…
Cosmology with a light ghost
Mikhail M. Ivanov, Anna A. Tokareva
We study the creation and evolution of cosmological perturbations in renormalizable quadratic gravity with a Weyl term. We adopt a prescription that implies the stability of the va…
Polarization of photons emitted by decaying dark matter
W. Bonivento, D. Gorbunov, M. Shaposhnikov +1
Radiatively decaying dark matter may be searched through investigating the photon spectrum of galaxies and galaxy clusters. We explore whether the properties of dark matter can be…
Scalaron production in contracting astrophysical objects
Dmitry Gorbunov, Anna Tokareva
We study the creation of high energy SM particles in the Starobinsky model of dark energy (a variant of F(R)-gravity) inside the regions contracting due to the Jeans instability. I…
