Does DESI prefer Damped Oscillating Dark Energy over Cosmological constant?
Saddam Hussain, Simran Arora, Qiang Wu +1
We investigate a dark-energy equation of state governed by a damped harmonic oscillator equation, admitting underdamped, critically damped, and overdamped solutions. Confronting th…
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…
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…
