Including beyond-linear halo bias in halo models
Alexander Mead, Licia Verde
We derive a simple prescription for including beyond-linear halo bias within the standard, analytical halo-model power spectrum calculation. This results in a corrective term that…
KiDS-1000 Cosmology: constraints beyond flat CDM
Tilman Tröster, Marika Asgari, Chris Blake +26
We present constraints on extensions to the flat CDM cosmological model by varying the spatial curvature , the sum of the neutrino masses , the dark energy equati…
Impact of cosmological signatures in two-point statistics beyond the linear regime
Dante V. Gomez-Navarro, Alexander Mead, Alejandro Aviles +1
Some beyond CDM cosmological models have dark-sector energy densities that suffer phase transitions. Fluctuations entering the horizon during such a transition can receive enhan…
HMcode-2020: Improved modelling of non-linear cosmological power spectra with baryonic feedback
Alexander Mead, Samuel Brieden, Tilman Tröster +1
We present an updated version of the HMcode augmented halo model that can be used to make accurate predictions of the non-linear matter power spectrum over a wide range of cosmolog…
