The Cosmic Mach Number as an Environment Measure for the Underlying Dark Matter Density Field
Romain Meriot, Sadegh Khochfar, Jose Onorbe +1
Using cosmological dark matter only simulations of a Gpc volume from the Legacy simulation project, we calculate Cosmic Mach Numbers (CMN) and perform a theoretical i…
Simulation based inference of the ionization history from the 2D 21 cm power spectrum
Nadia Cooper, Carina Norregaard, Romain Meriot +1
The 21 cm signal contains a wealth of information about the formation of the first stars and the reionization of the intergalactic medium during the Cosmic Dawn (CD) and Epoch of R…
Overview of 21cm Experiments at high redshift with SKAO
CD Science Working Group, Gianni Bernardi, Daniela Breitman +81
We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…
Comparison of Bayesian inference methods using the Loreli II database of hydro-radiative simulations of the 21-cm signal
Romain Meriot, Benoit Semelin, David Cornu
While the observation of the 21 cm signal from the Cosmic Dawn and Epoch of Reionization is an instrumental challenge, the interpretation of a prospective detection is still open t…
The LoReLi database: 21 cm signal inference with 3D radiative hydrodynamics simulations
Romain Meriot, Benoit Semelin
The Square Kilometer array is expected to measure the 21cm signal from the Epoch of Reionization (EoR) in the coming decade, and its pathfinders may provide a statistical detection…
Generative Models of 21cm EoR Lightcones with 3D Scattering Transforms
Ian Hothi, Erwan Allys, Benoit Semelin +1
The 21cm signal from the Epoch of Reionization (EoR) is observed as a three-dimensional data set known as a lightcone, consisting of a redshift (frequency) axis and two spatial sky…
Astrophysical constraints from future measurements of the kinetic Sunyaev-Zel'dovich power spectrum
Lisa McBride, Adélie Gorce, Marian Douspis +8
High-precision measurements of the Cosmic Microwave Background (CMB) will soon allow for the unprecedented detection of small-scale secondary anisotropies, such as the kinetic Suny…
