Rotating black holes dressed with cored-NFW dark matter produce larger image shifts, brightness asymmetries, and ring-scale changes than Kerr or Einasto-dressed cases, with partial degeneracy to spin and inclination.

Adaptive ray tracing, image diagnostics, and photon ring signatures of rotating dark-matter-dressed black holes
Rotating black holes dressed with cored-NFW dark matter produce larger image shifts, brightness asymmetries, and ring-scale changes than Kerr or Einasto-dressed cases, with partial degeneracy to spin and inclination.
