Assessing subhalo finders in cosmological hydrodynamical simulations
Victor J. Forouhar Moreno, John Helly, Robert McGibbon +5
Cosmological simulations are essential for inferring cosmological and galaxy population properties based on forward-modelling, but this typically requires finding the population of…
The FLAMINGO project: cosmology with the redshift dependence of weak gravitational lensing peaks
Jeger C. Broxterman, Matthieu Schaller, Henk Hoekstra +5
Weak gravitational lensing (WL) convergence peaks contain valuable cosmological information in the regime of non-linear collapse. Using the FLAMINGO suite of cosmological hydrodyna…
FLAMINGO: combining kinetic SZ effect and galaxy-galaxy lensing measurements to gauge the impact of feedback on large-scale structure
Ian G. McCarthy, Alexandra Amon, Joop Schaye +13
Energetic feedback processes associated with accreting supermassive black holes can expel gas from massive haloes and significantly alter various measures of clustering on ~Mpc sca…
The FLAMINGO project: Baryon effects on the matter power spectrum

Roi Kugel, Joop Schaye, Matthieu Schaller +2
Galaxy cluster counts have historically been important for the measurement of cosmological parameters and upcoming surveys will greatly reduce the statistical errors. To exploit th…
Validating the clustering predictions of empirical models with the FLAMINGO simulations
Sergio Contreras, Raul E. Angulo, Jonás Chaves-Montero +3
Context. Mock galaxy catalogues are essential for correctly interpreting current and future generations of galaxy surveys. Despite their significance in galaxy formation and cosmol…
Cosmic Web Dynamics: Forces and Strains
Roi Kugel, Rien van de Weygaert
This study concerns an inventory of the gravitational force and tidal field induced by filaments, walls, cluster nodes and voids on Megaparsec scales and how they assemble and shap…
The FLAMINGO Project: A comparison of galaxy cluster samples selected on mass, X-ray luminosity, Compton-Y parameter, or galaxy richness
Roi Kugel, Joop Schaye, Matthieu Schaller +5
Galaxy clusters provide an avenue to expand our knowledge of cosmology and galaxy evolution. Because it is difficult to accurately measure the total mass of a large number of indiv…
Dark photon constraints from CMB temperature anisotropies
Andres Aramburo-Garcia, Kyrylo Bondarenko, Alexey Boyarsky +6
The resonant conversion, within the inter-galactic medium, of regular photons into dark photons amplifies the anisotropy observed in the CMB, thereby imposing stringent constraints…
