A number of recent studies have found evidence for a tension between observations of large-scale structure (LSS) and the predictions of the standard model of cosmology with the cosmological parameters fit to the cosmic microwave background (CMB). The... Read More about The FLAMINGO project: revisiting the S8 tension and the role of baryonic physics.

Monthly Notices of the Royal Astronomical Society, 526(4), 6103-6127. https://doi.org/10.1093/mnras/stad2540

To fully take advantage of the data provided by large-scale structure surveys, we need to quantify the potential impact of baryonic effects, such as feedback from active galactic nuclei (AGN) and star formation, on cosmological observables. In simula... Read More about FLAMINGO: calibrating large cosmological hydrodynamical simulations with machine learning..

Where shadows lie: reconstruction of anisotropies in the neutrino sky (2023)
Journal Article

The Cosmic Neutrino Background (CNB) encodes a wealth of information, but has not yet been observed directly. To determine the prospects of detection and to study its information content, we reconstruct the phase-space distribution of local relic neu...

The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys (2023)
Journal Article
Schaye, J., Kugel, R., Schaller, M., Helly, . J. C., Braspenning, J., Elbers, W., …Nobels, F. S. J. (2023). The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys. Monthly Notices of the Royal Astronomical Society, 526(4), 4978–5020. https://doi.org/10.1093/mnras/stad2419

We introduce the Virgo Consortium’s FLAMINGO suite of hydrodynamical simulations for cosmology and galaxy cluster physics. To ensure the simulations are sufficiently realistic for studies of large-scale structure, the subgrid prescriptions for stella...

Persistent topology of the reionization bubble network – II. Evolution and classification (2023)
Journal Article
Elbers, W., & van de Weygaert, R. (2023). Persistent topology of the reionization bubble network – II. Evolution and classification. Monthly Notices of the Royal Astronomical Society, 520(2), 2709-2726. https://doi.org/10.1093/mnras/stad120

We study the topology of the network of ionized and neutral regions that characterized the intergalactic medium during the Epoch of Reionization. Our analysis uses the formalism of persistent homology, which offers a highly intuitive and comprehensiv... Read More about Persistent topology of the reionization bubble network – II.
