Constraining ModMax Black Holes with EHT and GRAVITY Observations: Optical Signatures and Accretion Disk Properties

Tursunali Xamidov, Mirjavoxir Mirkhaydarov, Sanjar Shaymatov +2

In this work, we study photon propagation and the radiative properties of a thin accretion disk around a ModMax black hole and examine the effects of the charge (i.e. $Q^2 = Q^…

Gravitational Wave Signatures of Schwarzschild Black Hole in a Generalized Dehnen-Type Dark Matter Halo

Bahromjon Shokirov, Arabboy Mirzakulov, Tursunali Xamidov +1

In this paper, we investigate timelike geodesic motion, periodic orbits, and the associated gravitational-wave signals around a Schwarzschild-like black hole (BH) embedded in a gen…

Constraints on Schwarzschild Black Hole in a Generalized Dehnen-Type Dark Matter Halo via the S2 Star Orbit around Sgr A

Tursunali Xamidov, Sanjar Shaymatov, Qiang Wu

The distribution of dark matter (DM) halo around supermassive black holes (BHs) may leave observable imprints on stellar dynamics near galactic centers. Motivated by this, we inves…

Observational Signatures of Exact Black Hole Solutions in a Dark Matter Halo

Azalbek Boltaev, Tursunali Xamidov, Sanjar Shaymatov

In this work, we derive novel exact solutions describing Schwarzschild-like black holes (BHs) embedded in a Dehnen-type dark matter (DM) halo density profile and investigate their…

Probing quantum corrected black hole through astrophysical tests with the orbit of S2 star and quasiperiodic oscillations

Tursunali Xamidov, Sanjar Shaymatov, Bobomurat Ahmedov +1

In this study, we explore the influence of the quantum correction parameter on the motion of particles and the properties of quasiperiodic oscillations (QPOs) around a quantum…

Gravitational wave signatures from periodic orbits around a Schwarzschild-Bertotti-Robinson black hole

Tursunali Xamidov, Sanjar Shaymatov, Qiang Wu +1

In this paper, we investigate periodic bound orbits and gravitational wave (GW) emission in the Schwarzschild-Bertotti-Robinson (Schwarzschild-BR) spacetime-an exact electrovacuum…
