Cross-simulator transfer with foundation model summaries: Towards robust SKA-era reionization inference
Yannic Pietschke, Caroline Heneka, Ayodele Ore +1
Simulation-based inference (SBI) for parameter estimation is vulnerable to model misspecification: neural summaries and density estimators trained on a specific forward model typic…
How X-rays heat the IGM in different 21-cm simulation codes: a comparison between Licorice and Beorn
Romain Meriot, Jonathan R. Pritchard, Timothée Schaeffer
Any interpretation of the 21-cm signal of neutral hydrogen using Bayesian inference methods can only be as accurate as the underlying simulation code used to model the state of the…
Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
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…
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…
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…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
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 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…
