Web-Halo Model Peak-Background Split (WHM-PBS): halo bias as a distribution, not a number
Samuel Brieden, Alexander Tipp
We present the Web--Halo Model Peak--Background Split (WHM-PBS), an analytic theory in which the large-scale bias of a dark-matter halo is inherited from its cosmic-web environment…
CHEFT: A Hybrid Effective Field Theory halo model
Marcos Pellejero Ibáñez, David Alonso, John A. Peacock +2
We present a hybrid halo model, which improves the description of the 2-halo term by incorporating non-linear information from simulations. A linear computation of the halo-halo po…
Web-Halo Model (WHM): Accurate non-linear matter power spectrum predictions without free parameters
Samuel Brieden, Florian Beutler, Marcos Pellejero-Ibañez
We present a parameter-free variant of the halo model that significantly improves the precision of matter clustering predictions, particularly in the challenging 1-halo to 2-halo t…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
