Superradiance in acoustic black hole
Chengye Yu, Xiaolin Zhang, Sobhan Kazempour +1
Rotating superradiance in cylindrical geometries has recently been observed experimentally using acoustic waves, shedding light on the superradiant phenomenon in black holes. In th…
Cosmology of Quasi-Dilaton Massive Gravity with Non-minimal Kinetic Coupling
Sobhan Kazempour, Amin Rezaei Akbarieh, Sichun Sun +1
In this study, we introduce an extension of the quasi-dilaton massive gravity theory and derive the field equations by varying the action with respect to the metric. This extension…
The Cosmological Impact of Brane-Chern-Simons Massive Gravity
Sobhan Kazempour, Amin Rezaei Akbarieh
In this paper, we present a novel extension of massive gravity theory; the Brane-Chern-Simons massive gravity theory. We explore the cosmological implications of this theory by der…
Accreting Black Holes in Dark Matter Halos
Sobhan Kazempour, Sichun Sun, Chengye Yu
We examine the thin accretion disk behaviors surrounding black holes embedded in cold dark matter halos and scalar field dark matter halos. We first calculate the event horizons an…
