Euclid Definition Study Report
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate theExpand

The size distribution of inhabited planets
Earth-like planets are expected to provide the greatest opportunity for the detection of life beyond the Solar system. However, our planet cannot be considered a fair sample, especially ifExpand

The Nature of Inhabited Planets and their Inhabitants
Earth-like planets are expected to provide the greatest opportunity for the detection of life beyond the Solar System. This notion stems from an assumption that the Earth constitutes a simple randomExpand

Clipping the cosmos: the bias and bispectrum of large scale structure.
A large fraction of the information collected by cosmological surveys is simply discarded to avoid length scales which are difficult to model theoretically. We introduce a new technique which enablesExpand

Cosmic Explosions, Life in the Universe, and the Cosmological Constant.
Gamma-ray bursts (GRBs) are copious sources of gamma rays whose interaction with a planetary atmosphere can pose a threat to complex life. Using recent determinations of their rate and probability ofExpand

Clipping the cosmos. II. Cosmological information from nonlinear scales
We present a method for suppressing contributions from higher-order terms in perturbation theory, greatly increasing the amount of information which may be extracted from the matter power spectrum.Expand

Marginalised Gaussian Processes with Nested Sampling
TLDR
This work presents an alternative learning procedure where the hyperparameters of the kernel function are marginalised using Nested Sampling to sample from complex, multi-modal distributions. Expand
KiDS-450: enhancing cosmic shear with clipping transformations
We present the first 'clipped' cosmic shear measurement using data from the Kilo-Degree Survey (KiDS-450). 'Clipping' transformations suppress the signal from the highest density, non-linear regionsExpand

Enhancing the cosmic shear power spectrum
Applying a transformation to a non-Gaussian field can enhance the information content of the resulting power spectrum, by reducing the correlations between Fourier modes. In the context of weakExpand
