General Relativity (GR), developed over 110 years ago, has successfully passed numerous astronomical tests. However, most of these tests have tested GR in the weak gravitational field approximation. Astronomers believe that stellar-mass black holes exist in binary systems, as well as supermassive black holes at the centers of galaxies. These astronomical objects offer the... -

New spherically symmetric smooth global solution of General Relativity with a scalar field is found. It is invariant under global Lorentz rotations. The geodesic equations admit four second rank involutive Killing tensors and are Liouville integrable. The scalar field potential is exponential. If the potential is bounded from below, solutions have cosmological interpretation.... -

A review of observational data from the Hubble and James Webb space telescopes, and ALMA array is presented. It is argued that the discovered contradiction between the observational data and standard ΛCDM cosmology is resolved if the Universe structure formation is seeded by primordial black holes. The proposed scenario is supported by the agreement with observations of the... -

Primordial black holes provide a distinctive theoretical laboratory for exploring the interplay between gravitational dynamics, nonequilibrium particle physics, and the thermal history of the early Universe. Across different mass regimes, their evolution is governed by competing processes, including gravitational accretion, cosmological expansion, and quantum evaporation. These... -

We construct static and axially symmetric magnetically charged hairy black holes in the gravity-coupled Weinberg-Salam theory. Large black holes merge with the Reissner-Nordstr\"om (RN) family, while the small ones are extremal and support a hair in the form of a ring-shaped electroweak condensate carrying superconducting W-currents and up to $22\%$ of the total magnetic charge.... -

When two black holes merge, the final black hole settles down by emitting gravitational waves at characteristic tones called quasinormal modes. In general relativity, these tones depend only on the black hole's mass and spin, so measuring several of them tests whether astrophysical black holes are exactly what Einstein's theory predicts. This is black hole spectroscopy. As...
