Designing Decisive Detections
R. Trotta, M. Kunz, A. R. Liddle
We present a general Bayesian formalism for the definition of Figures of Merit (FoMs) quantifying the scientific return of a future experiment. We introduce two new FoMs for future…
Detecting and distinguishing topological defects in future data from the CMBPol satellite
Pia Mukherjee, Jon Urrestilla, Martin Kunz +3
The proposed CMBPol mission will be able to detect the imprint of topological defects on the cosmic microwave background (CMB) provided the contribution is sufficiently strong. We…
The XMM Cluster Survey: X-ray analysis methodology
E. J. Lloyd-Davies, A. Kathy Romer, Nicola Mehrtens +20
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters using all publicly available data in the XMM-Newton Science Archive. Its main aims are to measure cosmolo…
Application of Bayesian model averaging to measurements of the primordial power spectrum
David Parkinson, Andrew R. Liddle
Cosmological parameter uncertainties are often stated assuming a particular model, neglecting the model uncertainty, even when Bayesian model selection is unable to identify a conc…
The XMM Cluster Survey: The build up of stellar mass in Brightest Cluster Galaxies at high redshift
J. P. Stott, C. A. Collins, M. Sahlen +14
We present deep J and Ks band photometry of 20 high redshift galaxy clusters between z=0.8-1.5, 19 of which are observed with the MOIRCS instrument on the Subaru Telescope. By usin…
The XMM Cluster Survey: Active Galactic Nuclei and Starburst Galaxies in XMMXCS J2215.9-1738 at z=1.46
Matt Hilton, Ed Lloyd-Davies, S. Adam Stanford +11
We use Chandra X-ray and Spitzer infrared observations to explore the AGN and starburst populations of XMMXCS J2215.9-1738 at z=1.46, one of the most distant spectroscopically conf…
Non-gaussianity in axion Nflation models
Soo A Kim, Andrew R Liddle, David Seery
We study perturbations in the multi-field axion Nflation model, taking account of the full cosine potential. We find significant differences with previous analyses which made a qua…
Stability of multi-field cosmological solutions in the presence of a fluid
Jonathan Frazer, Andrew R Liddle
We explore the stability properties of multi-field solutions in the presence of a perfect fluid, as appropriate to assisted quintessence scenarios. We show that the stability condi…
On the possibility of braneworld quintessential inflation
Mafalda Dias, Andrew R Liddle
We examine the possibility of achieving quintessential inflation, where the same field serves as both inflaton and quintessence, in the context of a five-dimensional braneworld. Br…
The Cosmological Parameters 2010
Ofer Lahav, Andrew R Liddle
This is a review article for The Review of Particle Physics 2010 (aka the Particle Data Book). It forms a compact review of knowledge of the cosmological parameters at the beginnin…
A dark energy view of inflation
Stéphane Ilic, Martin Kunz, Andrew R. Liddle +1
Traditionally, inflationary models are analyzed in terms of parameters such as the scalar spectral index ns and the tensor to scalar ratio r, while dark energy models are studied i…
