| Abstract: |
Recent measurements of the cosmic microwave background by Planck and by galaxy weak lensing surveys at low redshift have resulted in a marginal, yet intriguing discrepancy in the amplitude of matter density fluctuations, one of the fundamental parameters of the cosmological concordance model. I will present the most recent results of cosmological weak lensing analysis from the ESO Kilo-Degree Survey (KiDS), which has attained unprecedented robustness to systematic effects and confirms the mild tension with Planck. I will discuss the consistency of these results with other weak lensing surveys and with complementary probes of large-scale structure. Moreover, I will present new approaches to asserting the consistency of correlated datasets and demonstrate that there is no evidence for internal tension in KiDS weak lensing data. |
