abstract

We investigate the shadow cast of black holes immersed in a dark matter halo. We use the M87* shadow data obtained by the EHT collaboration to constrain two parameters ($M,a$) of dark matter halo surrounding a black hole with mass $M_{\rm bh}$. For $a\ge10.8M$, we find the favored region (shadow bound), while the disfavored region is found for $a<10.8M$ when imposing the EHT results. This shadow bound is much less than the observation bound of galaxies ($a\ge 10^4 M$).

    gr-qc 2025-09 conditional novelty 4.0 of 10

    For black holes embedded in Hernquist dark matter halos, the shadow radius and quasinormal mode frequencies are redshifted by a factor 1 - C + C^2/6 in the halo compactness C, with EHT observations implying C <= 0.092.
