Scale-dependent local primordial non-Gaussianity as a solution to the $S_{8}$ tension

Clément Stahl, Benoit Famaey, Rodrigo Ibata +3

For the last decade, several probes have pointed to a cosmological tension between the amplitude of density fluctuations extrapolated from the cosmic microwave background within th…

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 ( $∣ f_{NL} ∣ \sim 1000$ ), at small (Mpc) scales, can help in forming simulated…
