In this context, stellar-mass black holes (sBHs) have recently emerged as particularly promising targets [46]. The adiabatic growth [46, 47] of a black hole can gravitationally compress the surrounding dark matter distribution, leading to the formation of dense mini-spikes [47, 48] that substantially enhance the expected gamma-ray flux. Recent analyses based on 17 years of observations by theFermiLarge Area Telescope (LAT) [49] have exploited this mechanism to derive remarkably stringent limits on the dark matter annihilation cross section from the absence of gamma-ray excesses around stellar- mass black holes [50].
