Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Assessing non-linear models for galaxy clustering III: Theoretical accuracy for Stage IV surveys
Benjamin Bose, Kazuya Koyama, Hans A. Winther
We provide in depth MCMC comparisons of two different models for the halo redshift space power spectrum, namely a variant of the commonly applied Taruya-Nishimichi-Saito (TNS) mode…
The observed galaxy bispectrum from single-field inflation in the squeezed limit
Kazuya Koyama, Obinna Umeh, Roy Maartens +1
Using the consistency relation in Fourier space, we derive the observed galaxy bispectrum from single-field inflation in the squeezed limit, in which one of the three modes has a w…
A Perturbative Approach to the Redshift Space Correlation Function: Beyond the Standard Model
Benjamin Bose, Kazuya Koyama
We extend our previous redshift space power spectrum code to the redshift space correlation function. Here we focus on the Gaussian Streaming Model (GSM). Again, the code accommoda…
Speeding up -body simulations of modified gravity: Chameleon screening models
Sownak Bose, Baojiu Li, Alexandre Barreira +5
We describe and demonstrate the potential of a new and very efficient method for simulating certain classes of modified gravity theories, such as the widely studied gravity…
Relativistic Interpretation of Newtonian Simulations for Cosmic Structure Formation
Christian Fidler, Thomas Tram, Cornelius Rampf +3
The standard numerical tools for studying non-linear collapse of matter are Newtonian -body simulations. Previous work has shown that these simulations are in accordance with Ge…
