From inflation to dark matter halo profiles: the impact of primordial non-Gaussianities on the central density cusp

Clément Stahl, Nicolas Mai, Benoit Famaey +2

It has recently been shown that local primordial non-Gaussianities (PNG) with significant amplitude ($|f_{\mathrm{NL}}|\sim 1000$), at small (Mpc) scales, can help in forming simulated…
