Probing galaxy bias and intergalactic gas pressure with KiDS Galaxies-tSZ-CMB lensing cross-correlations
Ziang Yan, Ludovic van Waerbeke, Tilman Tröster +14
We constrain the redshift dependence of gas pressure bias (bias-weighted average electron pressure), which characterises the thermo…
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…
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…
Axion Quark Nugget Dark Matter: Time Modulations and Amplifications
Xunyu Liang, Alexander Mead, Md Shahriar Rahim Siddiqui +2
We study the new mechanism of the axion production suggested recently in [1,2]. This mechanism is based on the so-called Axion Quark Nugget (AQN) dark matter model, which was origi…
Modelling baryonic feedback for survey cosmology
Nora Elisa Chisari, Alexander J. Mead, Shahab Joudaki +10
Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between to elucidate the nature of dark matter and dark e…
