Photon sphere for a dyonic black hole corresponding to Toda chain

Vladimir D. Ivashchuk, Evgeny E. Trubach

We consider a dilatonic dyon black hole solution with a gravitational radius of and two charges, (electric) and (magnetic), within the framework of a four-dimensi…

Quasinormal modes in the field of a dyon-like dilatonic black hole corresponding to Toda chain

U. S. Kayumov, S. V. Bolokhov, V. D. Ivashchuk +2

We explore the quasinormal modes of a massless test scalar field in the gravitational background of a non-extremal dilatonic dyonic black hole. The dyon-like black hole solution is…

Photon spheres near black holes in a model with anisotropic fluid

V. D. Ivashchuk, S. V. Bolokhov, F. B. Belissarova +4

The semi-review paper studies the null geodesics which appear for black hole solutions in the gravitational model with anisotropic fluid. The equations of state for the fluid…

The fine structure constant: a review of measurement results and possible space-time variations

K. A. Bronnikov, V. D. Ivashchuk, V. V. Khruschov

A brief description of the main methods for determining the fine structure constant is given. It is shown that the exact value of the fine structure constant is important for the n…
