Reionisation time field reconstruction from 21-cm Maps: Investigating predictor coherence in WDM cosmology
Julien Hiegel, Dominique Aubert, Émilie Thélie +2
The reionisation time field treion(r) captures the entire history of cosmic reionisation by mapping the moment where each region of the Universe became ionised. Previous work has s…

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…

Reionisation time fields reconstruction from 21 cm signal maps
Julien Hiegel, Emilie Thélie, Dominique Aubert +6
During the Epoch of reionisation, the intergalactic medium is reionised by the UV radiation from the first generation of stars and galaxies. One tracer of the process is the 21 cm…
