The SRG-eROSITA All-Sky Survey : Constraints on f(R) Gravity from Cluster Abundance
E. Artis, V. Ghirardini, E. Bulbul +28
The evolution of the cluster mass function traces the growth of the linear density perturbations and can be utilized for constraining the parameters of cosmological and alternative…
On the road to percent accuracy: The Reaction Way
Matteo Cataneo
Taking advantage of the unprecedented statistical power of upcoming cosmic shear surveys will require exquisite knowledge of the matter power spectrum over a wide range of scales.…

Matteo Cataneo, Cora Uhlemann, Christian Arnold +3
We present an analytical description of the probability distribution function (PDF) of the smoothed three-dimensional matter density field for modified gravity and dark energy. Our…
On the road to percent accuracy V: the non-linear power spectrum beyond CDM with massive neutrinos and baryonic feedback
Benjamin Bose, Bill S. Wright, Matteo Cataneo +7
In the context of forthcoming galaxy surveys, to ensure unbiased constraints on cosmology and gravity when using non-linear structure information, percent-level accuracy is require…
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…
On the road to percent accuracy IV: ReACT -- computing the non-linear power spectrum beyond CDM
Benjamin Bose, Matteo Cataneo, Tilman Tröster +3
To effectively exploit large-scale structure surveys, we depend on accurate and reliable predictions of non-linear cosmological structure formation. Tools for efficient and compreh…
Hybrid : general, unified, non-linear matter power spectrum in redshift space
Benjamin Bose, Hans A. Winther, Alkistis Pourtsidou +4
Constraints on gravity and cosmology will greatly benefit from performing joint clustering and weak lensing analyses on large-scale structure data sets. Utilising non-linear inform…
On the road to percent accuracy III: non-linear reaction of the matter power spectrum to massive neutrinos
Matteo Cataneo, J. D. Emberson, Derek Inman +2
We analytically model the non-linear effects induced by massive neutrinos on the total matter power spectrum using the halo model reaction framework of Cataneo et al. 2019. In this…
On the road to percent accuracy II: calibration of the non-linear matter power spectrum for arbitrary cosmologies
Benjamin Giblin, Matteo Cataneo, Ben Moews +1
We introduce an emulator approach to predict the non-linear matter power spectrum for broad classes of beyond-CDM cosmologies, using only a suite of CDM -body simulations.…
Tests of Gravity with Galaxy Clusters
Matteo Cataneo, David Rapetti
Changes in the law of gravity have far-reaching implications for the formation and evolution of galaxy clusters, and appear as peculiar signatures in their mass-observable relation…

Matteo Cataneo, Lucas Lombriser, Catherine Heymans +4
We present a general method to compute the nonlinear matter power spectrum for dark energy and modified gravity scenarios with percent-level accuracy. By adopting the halo model an…
Cold dark energy constraints from the abundance of galaxy clusters
Caroline Heneka, David Rapetti, Matteo Cataneo +3
We constrain cold dark energy of negligible sound speed using galaxy cluster abundance observations. In contrast to standard quasi-homogeneous dark energy, negligible sound speed i…

Matteo Cataneo, David Rapetti, Lucas Lombriser +1
We refine the mass and environment dependent spherical collapse model of chameleon gravity by calibrating a phenomenological correction inspired by the parameterized post-Fr…
Efficient exploration of cosmology dependence in the EFT of LSS
Matteo Cataneo, Simon Foreman, Leonardo Senatore
The most effective use of data from current and upcoming large scale structure~(LSS) and CMB observations requires the ability to predict the clustering of LSS with very high preci…
