Euclid Definition Study Report
- R. Laureijs, J. Amiaux, +216 authors E. Zucca
- Physics
- 14 October 2011
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 the… Expand
The size distribution of inhabited planets
- F. Simpson
- Physics
- 15 March 2015
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 if… Expand
The Nature of Inhabited Planets and their Inhabitants
- F. Simpson
- Physics
- 15 March 2015
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 random… Expand

Clipping the cosmos: the bias and bispectrum of large scale structure.
- F. Simpson, J. James, A. Heavens, C. Heymans
- Medicine, Physics
- Physical review letters
- 26 July 2011
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 enables… Expand
Cosmic Explosions, Life in the Universe, and the Cosmological Constant.
- T. Piran, R. Jiménez, A. Cuesta, F. Simpson, L. Verde
- Physics, Medicine
- Physical review letters
- 5 August 2015
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 of… Expand
Clipping the cosmos. II. Cosmological information from nonlinear scales
- F. Simpson, A. Heavens, C. Heymans
- Physics
- 26 June 2013
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

KiDS-450: enhancing cosmic shear with clipping transformations
- B. Giblin, C. Heymans, +12 authors T. Troster
- Physics
- 30 May 2018
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 regions… Expand
Enhancing the cosmic shear power spectrum
- F. Simpson, J. Harnois-D'eraps, C. Heymans, Raúl Jiménez, B. Joachimi, L. Verde
- Physics
- 17 July 2015
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 weak… Expand
