Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mustapha Azreg-Aïnou, Mubasher Jamil +1
Extreme mass-ratio inspirals (EMRIs) are among the most powerful probes of strong-field gravity and of the environments surrounding supermassive compact objects. Motivated by the e…

Exploring potential astrophysical applications of black holes in nonlinear electrodynamics
Marco A. A. de Paula, Mustapha Azreg-Aïnou
Spacetimes arising from nonlinear electrodynamics (NED) are a good laboratory for studying both the nature of regular black holes (RBH) solutions and the imprints of nonlinear elec…

Constraints on Kalb-Ramond Gravity from EHT Observations of Rotating Black Holes in Traceless Conformal Electrodynamics
Yassine Sekhmani, Kuantay Boshkayev, Mustapha Azreg-Aïnou +3
We present a phenomenological study of rotating, charged black holes in Einstein gravity coupled to a traceless (conformal) matter sector formed by ModMax nonlinear electrodynamics…
