A first look at the topology of reionization redshifts in models of the Epoch of the Reionization

Emilie Thélie, Dominique Aubert, Nicolas Gillet +1

During the EoR, the first stars and galaxies appear while creating ionized bubbles that will eventually percolate near z=6. These ionized bubbles and percolation process are nowada…

Machine learning astrophysics from 21 cm lightcones: impact of network architectures and signal contamination

David Prelogović, Andrei Mesinger, Steven Murray +2

Imaging the cosmic 21 cm signal will map out the first billion years of our Universe. The resulting 3D lightcone (LC) will encode the properties of the unseen first galaxies and ph…

Lyman-alpha opacities at z=4-6 require low mass, radiatively-suppressed galaxies to drive cosmic reionization

Pierre Ocvirk, Joseph S. W. Lewis, Nicolas Gillet +4

The high redshift Lyman-alpha forest, in particular the Gunn-Peterson trough, is the most unambiguous signature of the neutral to ionized transition of the intergalactic medium (IG…

Constraints on warm dark matter from UV luminosity functions of high-z galaxies with Bayesian model comparison

Anton Rudakovskyi, Andrei Mesinger, Denys Savchenko +1

The number density of small dark matter (DM) halos hosting faint high-redshift galaxies is sensitive to the DM free-streaming properties. However, constraining these DM properties…

21cm signal predictions at Cosmic Dawn and Reionization with coupled radiative-hydrodynamics

Nicolas J. F. Gillet, Dominique Aubert, Florent G. Mertens +1

The process of heating and reionization of the Universe at high redshift links small scale structures/galaxy formation and large scale inter-galactic medium properties. Even if the…

The interplay of fast waves and slow convection in geodynamo simulations nearing Earth's core conditions

Julien Aubert, Nicolas Gillet

Ground observatory and satellite-based determinations of temporal variations in the geomagnetic field probe a decadal to annual time scale range where Earth's core slow, inertiales…
