The resummation model in FLAMINGO: precisely predicting matter power suppression from observed halo baryon fractions

Marcel P. van Daalen, Ioannis Koutalios, Jeger C. Broxterman +4

In order to derive unbiased cosmological parameters from Stage-IV surveys, we need models that can predict the matter power spectrum for at least $k\,\lesssim\,10\,h\mathrm{\,Mpc^{…

FLAMINGO: Baryonic effects on the weak lensing scattering transform

Mariia Marinichenko, Marcel P. van Daalen, Elena Sellentin +3

The scattering transform is a wavelet-based statistic capable of capturing non-Gaussian features in weak lensing (WL) convergence maps and has been proven to tighten cosmological p…

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

Matthieu Schaller, Joop Schaye, Roi Kugel +2

The effect of baryon physics associated with galaxy formation onto the large-scale matter distribution of the Universe is a key uncertainty in the theoretical modelling required fo…

Simultaneously Modelling Dusty Star Forming Galaxies and Massive Quiescents: A Calibration Framework for Galaxy Formation Models

Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +4

Galaxy formation models, particularly semi-analytic models (SAMs), rely on differential equations with free parameters to describe the physical mechanisms governing galaxy formatio…

The FLAMINGO project: the coupling between baryonic feedback and cosmology in light of the tension

Willem Elbers, Carlos S. Frenk, Adrian Jenkins +12

Large-scale structure surveys have reported measurements of the density of matter, , and the amplitude of clustering, , that are in tension with the values inf…
