    • Combined constraints on deviations of dark energy from an ideal fluid from Euclid and Planck 
      Majerotto, Elisabetta; Sapone, Doménico; Schäfer, Björn Malte (Oxford University Press, 2016)
      Cosmological fluids are commonly assumed to be distributed in a spatially homogeneous way, while their internal properties are described by a perfect fluid. As such, they influence the Hubble expansion through their ...

      Aims. Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear.Methods. We present an "end-to-end" approach that introduces sources of bias in a modelled weak ...

L.; Sureau, F.; Taylor, A. N.; Tereno, I.; Toledo Moreo, R.; Valenziano, L.; Wang, Y.; Zoubian, J. (EDP Sciences, 2020)
      Context. Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordingly, previously ignored systematic ...
    • LoCuSS: Testing hydrostatic equilibrium in galaxy clusters 
      Smith, G. P.; Mazzotta, P.; Okabe, N.; Ziparo, F.; Mulroy, S. L.; Babul, A.; Finoguenov, A.; McCarthy, I. G.; Lieu, M.; Bahé, Y. M.; Bourdin, H.; Evrard, A. E.; Futamase, T.; Haines, Chris; Jauzac, M.; Marrone, D. P.; Martino, R.; May, P. E.; Taylor, J. E.; Umetsu, K. (Oxford University Press, 2016)
      We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 ...
    • Shapley Supercluster Survey: Galaxy evolution from filaments to cluster cores
