LATEST RESEARCH HIGHLIGHT
New exciting research coming from the KiDS collaboration. In a series of two papers we draw cosmological inference from the number of density peaks found in the KiDS weak lensing data which spans roughly 450 square degrees of the sky. The first analysis of Shan et al. (2017) focuses on high signal-to-noise peaks found in surface-mass density maps of the KiDS fields, while Martinet et al. (2017) uses lower signal-to-noise peaks found in aperture mass maps derived directly from the KiDS weak lensing catalogues. Both papers find similar numbers for key cosmological parameters, where the first paper uses an analytic model to derive theoretical predictions where the second one relies on numerical simulations. Both analyses are consistent with the original KiDS cosmology results of Hildebrandt et al. (2017), which relies on the two-point correlation function of galaxy ellipticities.

I am a Marie Curie Fellow at INAF - Osservatorio Astronomico di Bologna. 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.
