Estimating the weak-lensing rotation signal in radio cosmic shear surveys
Daniel B. Thomas, Lee Whittaker, Stefano Camera +1
Weak lensing has become an increasingly important tool in cosmology and the use of galaxy shapes to measure cosmic shear has become routine. The weak-lensing distortion tensor cont…
An extensive investigation of the Generalised Dark Matter model
Michael Kopp, Constantinos Skordis, Dan B. Thomas
The Cold Dark Matter (CDM) model, wherein the dark matter is treated as a pressureless perfect fluid, provides a good fit to galactic and cosmological data. With the advent of prec…
Constraining dark matter properties with Cosmic Microwave Background observations
Daniel B. Thomas, Michael Kopp, Constantinos Skordis
We examine how the properties of dark matter, parameterised by an equation of state parameter and two perturbative Generalised Dark Matter (GDM) parameters (the sound s…
