LATEST RESEARCH HIGHLIGHT
Here is our latest CLASH result and in collaboration with members of the Planck team. In this paper we use the lensing-derived masses of CLASH clusters published in Merten et al. (2015) to determine the mass scale of clusters detected via the thermal Sunyaev Zel'dovich effect. A concise Bayesian analysis framework properly accounts for the CLASH selection function and potential systematic effects. The analysis finds a bias of 1-b_sz = 0.73 +/- 0.10 between true cluster masses and the Planck SZ mass proxy. This result is in good agreement with other studies and goes a long way towards reconciling the mild tension between predictions from the Planck primary CMB analysis and Planck cluster counts (see figure below).

I am a Marie Curie Fellow in the department of Physics at the University of Oxford. I am a Cosmologist and interested in the composition and evolution of the Universe as a whole. My main research aim is to understand the elusive dark matter via the study of cosmic structure formation.
My teaching activities build around my assignment as stipendiary lecturer at University College Oxford where I teach Relativity and Optics to first and third year Physics students. Oxford is a special place to study with its collegiate structure and the personal tutorial experience at the colleges. It is this unique combination that makes Oxford so successful.
