Modified Gravity: the CMB, Weak Lensing and General Parameterisations
Shaun A. Thomas, Stephen A. Appleby, Jochen Weller
We examine general physical parameterisations for viable gravitational models in the framework. This is related to the mass of an additional scalar field, called the scalaro…
Separate Universes Do Not Constrain Primordial Black Hole Formation
Michael Kopp, Stefan Hofmann, Jochen Weller
Carr and Hawking showed that the proper size of a spherical overdense region surrounded by a flat FRW universe cannot be arbitrarily large as otherwise the region would close up on…
Constraining warm dark matter with cosmic shear power spectra
Katarina Markovič, Sarah Bridle, Anže Slosar +1
We investigate potential constraints from cosmic shear on the dark matter particle mass, assuming all dark matter is made up of light thermal relic particles. Given the theoretical…
Parameterizing scalar-tensor theories for cosmological probes
Stephen A Appleby, Jochen Weller
We study the evolution of density perturbations for a class of models which closely mimic CDM background cosmology. Using the quasi-static approximation, and the fact tha…
The potential of X-ray cluster surveys to constrain primordial non-Gaussianity
B. Sartoris, S. Borgani, C. Fedeli +4
We present forecasts for constraints on deviations from Gaussian distribution of primordial density perturbations from future X-ray surveys of galaxy clusters. Our analysis is base…
