Quasinormal frequencies and greybody factors for axial perturbations of dilaton-Euler-Heisenberg de Sitter black holes
Ming Zhang, Guo-Xin Chen, Xufen Zhang +4
We investigate the quasinormal modes (QNMs) and greybody factors of dilaton-Euler-Heisenberg (dEH) de Sitter (dS) black holes in string-inspired Euler-Heisenberg gravity. Since the…
Quasinormal modes of massless scalar and electromagnetic perturbations for Euler-Heisenberg black holes surrounded by perfect fluid dark matter
Chengfu Feng, Sheng-Yuan Li, Xufen Zhang +3
We investigate the quasinormal modes of massless scalar and electromagnetic perturbations in charged Euler--Heisenberg black holes surrounded by perfect fluid dark matter. The quas…
A microphysically inspired approach to dark matter-dark energy interactions: first bounds on dark-sector scattering cross sections
A. A. Escobal, F. B. Abdalla, J. F. Jesus +4
The observational tension regarding the value of the Hubble constant () has motivated the exploration of alternative cosmological scenarios, including Interacting Dark Energy…
Probing Dark Matter Spike with Gravitational Waves from Early EMRIs in the Milky Way Center
Chen Feng, Yong Tang, Yue-Liang Wu
Cold dark matter may form dense structures around supermassive black holes (SMBHs), significantly influencing their local environments. These dense regions are ideal sites for the…
