Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Extending cosmological tests of General Relativity with the Square Kilometre Array
Philip Bull
Tests of general relativity (GR) are still in their infancy on cosmological scales, but forthcoming experiments promise to greatly improve their precision over a wide range of dist…
Weighing neutrinos with cosmic neutral hydrogen
Francisco Villaescusa-Navarro, Philip Bull, Matteo Viel
We investigate the signatures left by massive neutrinos on the spatial distribution of neutral hydrogen (HI) in the post-reionization era by running hydrodynamic simulations that i…
A systematic study of Lyman-Alpha transfer through outflowing shells: Model parameter estimation
Max Gronke, Philip Bull, Mark Dijkstra
Outflows promote the escape of Lyman- (Ly) photons from dusty interstellar media. The process of radiative transfer through interstellar outflows is often modelled by a spher…
Observational signatures of modified gravity on ultra-large scales
Tessa Baker, Philip Bull
Extremely large surveys with future experiments like Euclid and the SKA will soon allow us to access perturbation modes close to the Hubble scale, with wavenumbers $k \sim \mathcal…
Ultra large-scale cosmology in next-generation experiments with single tracers
David Alonso, Philip Bull, Pedro G. Ferreira +2
Future surveys of large-scale structure will be able to measure perturbations on the scale of the cosmological horizon, and so could potentially probe a number of novel relativisti…
Measuring baryon acoustic oscillations with future SKA surveys
Philip Bull, Stefano Camera, Alvise Raccanelli +4
The imprint of baryon acoustic oscillations (BAO) in large-scale structure can be used as a standard ruler for mapping out the cosmic expansion history, and hence for testing cosmo…
Cosmology from HI galaxy surveys with the SKA
Filipe B. Abdalla, Philip Bull, Stefano Camera +8
The Square Kilometer Array (SKA) has the potential to produce galaxy redshift surveys which will be competitive with other state of the art cosmological experiments in the next dec…
HI galaxy simulations for the SKA: number counts and bias
Mario G. Santos, David Alonso, Philip Bull +2
This chapter describes the assumed specifications and sensitivities for HI galaxy surveys with SKA1 and SKA2. It addresses the expected galaxy number densities based on available s…
Euclid & SKA Synergies
Thomas D. Kitching, David Bacon, Michael L. Brown +7
Over the past few years two of the largest and highest fidelity experiments conceived have been approved for construction: Euclid is an ESA M-Class mission that will map three-quar…
Synergy between the Large Synoptic Survey Telescope and the Square Kilometre Array
David Bacon, Sarah Bridle, Filipe B. Abdalla +18
We provide an overview of the science benefits of combining information from the Square Kilometre Array (SKA) and the Large Synoptic Survey Telescope (LSST). We first summarise the…
Cross correlation surveys with the Square Kilometre Array
Donnacha Kirk, Aurélien Benoit-Lévy, Filipe B. Abdalla +2
By the time that the first phase of the Square Kilometre Array is deployed it will be able to perform state of the art Large Scale Structure (LSS) as well as Weak Gravitational Len…
Foreground Subtraction in Intensity Mapping with the SKA
Laura Wolz, Filipe B. Abdalla, David Alonso +7
21cm intensity mapping experiments aim to observe the diffuse neutral hydrogen (HI) distribution on large scales which traces the Cosmic structure. The Square Kilometre Array (SKA)…
