Descripción
The 21-cm signal is emerging as a promising probe of dark matter. However, heating-based constraints are strongly affected by astrophysical uncertainties entering in the choice of fiducial model. I will illustrate this effect for accreting primordial black holes with masses in the range $1-10^3 \, M_{\odot}$. To address this issue, I will then introduce a novel mechanism in which dark matter can boost the 21-cm signal through exotic Lyman-$\alpha$ photons, potentially offering a more robust avenue for constraining dark matter.
