Quasi-normal modes of naked singularities in presence of non-linear scalar fields
O. S. Stashko, O. V. Savchuk, V. I. Zhdanov
We study linear perturbations against static spherically symmetric background configurations of General Relativity with a real scalar field (SF), which is minimally coupled with gr…
Circular orbits of test particles interacting with massless linear scalar field of the naked singularity
O. S. Stashko, V. I. Zhdanov
We study effects of the particles coupling with scalar field (SF) on the distribution of stable circular orbits (SCO) around the naked singularity described by the well-known Fishe…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Thin accretion discs around spherically symmetric configurations with nonlinear scalar fields
O. S. Stashko, V. I. Zhdanov, A. N. Alexandrov
We study stable circular orbits (SCO) around static spherically symmetric configuration of General Relativity with a non-linear scalar field (SF). The configurations are described…
Verification of Einstein's formula for gravitational deflection of light using observations of Galactic microlensing
A. N. Alexandrov, V. M. Sliusar, V. I. Zhdanov
The potential of the gravitational microlensing inside our Galaxy for testing the Einstein formula for the gravitational light deflection is discussed. For this purpose, the lens m…
Static spherically symmetric configurations with N non-linear scalar fields: global and asymptotic properties
V. I. Zhdanov, O. S. Stashko
In case of a spherically symmetric non-linear scalar field (SF) in flat space, besides singularity at the center, spherical singularities can occur for non-zero values of radial va…
