Low-frequency absorption cross sections and high-frequency deflection angles are approximated for charged massive scalars on RN black holes with PFDM, with numerics showing strong suppression by dark matter parameter λ and enhanced superradiant amplification compared to pure RN.

Dark energy stars from modified Chaplygin gas obey C-I-Λ-f universal relations similar to quark stars but are distinguishable via I-Eg^{-2}, Λ-Eg^{-5}, and f-Eg^{-2} relations, with GW170817 used to predict 1.4 solar-mass properties.
Euler-Heisenberg coupling and surrounding matter fields modify the temperature profile, stability structure, and critical point location of AdS black holes, while changing Hawking radiation sparsity, photon sphere, and shadow size.
