Fast Generation of Weak Lensing Maps in Modified Gravity with COLA
Sophie Hoyland, Hans A. Winther, Daniela Saadeh +2
Accurate predictions of weak lensing observables are essential for understanding the large-scale structure of the Universe and probing the nature of gravity. In this work, we prese…
Studying large-scale structure probes of modified gravity with COLA
Bartolomeo Fiorini, Kazuya Koyama, Albert Izard
We study the effect of two Modified Gravity (MG) theories, and nDGP, on three probes of large-scale structure, the real space power spectrum estimator , bispectrum and…
Dark Energy Survey Year 3 Results: Galaxy mock catalogs for BAO analysis
I. Ferrero, M. Crocce, I. Tutusaus +83
The calibration and validation of scientific analysis in simulations is a fundamental tool to ensure unbiased and robust results in observational cosmology. In particular, mock gal…
Fast generation of mock galaxy catalogues in modified gravity models with COLA
Bartolomeo Fiorini, Kazuya Koyama, Albert Izard +3
We investigate the viability of producing galaxy mock catalogues with COmoving Lagrangian Acceleration (COLA) simulations in Modified Gravity (MG) models employing the Halo Occupat…
WFIRST: The Essential Cosmology Space Observatory for the Coming Decade
O. Doré, C. Hirata, Y. Wang +46
Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology and arguably in all of physics. Either the Universe is dominated by a form of da…
Comparing approximate methods for mock catalogues and covariance matrices III: Bispectrum
Manuel Colavincenzo, Emiliano Sefusatti, Pierluigi Monaco +19
We compare the measurements of the bispectrum and the estimate of its covariance obtained from a set of different methods for the efficient generation of approximate dark matter ha…
