Constraints on modified gravity from the BOSS galaxy survey
Lorenzo Piga, Marco Marinucci, Guido D'Amico +3
We develop a pipeline to set new constraints on scale-independent modified gravity, from the galaxy power spectrum in redshift space of BOSS DR12. The latter is modelled using the…
Euclid: Modelling massive neutrinos in cosmology -- a code comparison
J. Adamek, R. E. Angulo, C. Arnold +133
The measurement of the absolute neutrino mass scale from cosmological large-scale clustering data is one of the key science goals of the Euclid mission. Such a measurement relies o…
: Fast, approximate simulations of structure formation in Horndeski gravity
Bill S. Wright, Ashim Sen Gupta, Tessa Baker +2
We introduce , a code designed to run fast, approximate -body simulations of non-linear structure formation in reduced Horndeski gravity. Given an inp…
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…
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…
Investigating the degeneracy between modified gravity and massive neutrinos with redshift-space distortions
Bill S. Wright, Kazuya Koyama, Hans A. Winther +1
There is a well known degeneracy between the enhancement of the growth of large-scale structure produced by modified gravity models and the suppression due to the free-streaming of…
Constraining the time variation of Newton's constant with gravitational-wave standard sirens and supernovae
Wen Zhao, Bill S. Wright, Baojiu Li
The intrinsic peak luminosity of Type Ia supernovae (SNIa) depends on the value of Newton's gravitational constant , through the Chandrasekhar mass .…
Type Ia supernovae, standardisable candles, and gravity
Bill S. Wright, Baojiu Li
Type Ia supernovae (SNIe) are generally accepted to act as standardisable candles, and their use in cosmology led to the first confirmation of the as yet unexplained accelerated co…
COLA with massive neutrinos
Bill S. Wright, Hans A. Winther, Kazuya Koyama
The effect of massive neutrinos on the growth of cold dark matter perturbations acts as a scale-dependent Newton's constant and leads to scale-dependent growth factors just as we o…
COLA with scale-dependent growth: applications to screened modified gravity models
Hans A. Winther, Kazuya Koyama, Marc Manera +2
We present a general parallelized and easy-to-use code to perform numerical simulations of structure formation using the COLA (COmoving Lagrangian Acceleration) method for cosmolog…
