A primordial origin to cosmic tensions: towards reconciling and with early dark energy and scale-dependent primordial non-Gaussianities
Clément Stahl, Vivian Poulin, Benoit Famaey +1
The Hubble () tension between direct measurements of the expansion rate and the prediction of the CDM cosmological model calibrated on the Cosmic Microwave Background (CMB)…
A cosmic degeneracy story: structure formation with warm dark matter and scale-dependent primordial non-Gaussianities
Clément Stahl, Benoit Famaey, Rodrigo Ibata +2
It has been recently shown that cosmological models with scale-dependent primordial non-Gaussianities (sPNG) could provide a possible path to solve current cosmic tensions. Moreove…
Scale-dependent local primordial non-Gaussianity as a solution to the 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 (), at small (Mpc) scales, can help in forming simulated…
