EFT-Ramses: a code to simulate the effective field theory of dark energy
Nathaniel Ota Woodcock, Sownak Bose, Yunhao Gao +1
While the standard CDM paradigm is in excellent agreement with most current cosmological observations, theoretical challenges surrounding the cosmological constant () have st…
Galaxy formation in modified gravity -- II. galaxy halo connection and assembly bias
Michael Collier, Sownak Bose, Baojiu Li
Modern surveys such as DESI and \textit{Euclid}, which collect data for hundreds of millions of galaxies to map the large-scale structure (LSS) of the Universe, hold the key to det…
A modern halo streaming model for redshift space distortions
Cheng-Zong Ruan, Baojiu Li, Carlton M. Baugh +3
Accurate modelling of redshift-space distortions (RSD) in galaxy clustering is essential for extracting cosmological information from current and forthcoming large-scale structure…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Emulation of modified gravity from CDM using conditional GANs
Yash Gondhalekar, Sownak Bose, Baojiu Li +1
A major aim of cosmological surveys is to test deviations from the standard CDM model, but the full scientific value of these surveys will only be realised through efficient si…
