The XMM Cluster Survey: Forecasting cosmological and cluster scaling-relation parameter constraints
Martin Sahlén, Pedro T. P. Viana, Andrew R. Liddle +16
We forecast the constraints on the values of sigma_8, Omega_m, and cluster scaling relation parameters which we expect to obtain from the XMM Cluster Survey (XCS). We assume a flat…
Quintessence reconstructed: new constraints and tracker viability
Martin Sahlén, Andrew R Liddle, David Parkinson
We update and extend our previous work reconstructing the potential of a quintessence field from current observational data. We extend the cosmological dataset to include new super…
Direct reconstruction of the quintessence potential
Martin Sahlén, Andrew R. Liddle, David Parkinson
We describe an algorithm which directly determines the quintessence potential from observational data, without using an equation of state parametrisation. The strategy is to numeri…
