A hydrodynamical simulations-based model that connects the FRB DM--redshift relation to suppression of the matter power spectrum via feedback
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Understanding the impact of baryonic feedback on the small-scale (Mpc) matter power spectrum is a key astrophysical challenge, and essential for interpreti…
