    1. 10. Tension metrics in cosmology
      Dr Susana J. Landau (Universidad de Buenos Aires)

      In this talk, I will describe a novel estimator to quantify statistical tensions among multiple cosmological datasets simultaneously. This estimator generalizes the Difference-in-Means statistic, $Q_{\rm DM}$, to the multi-dataset regime. Our framework enables the detection of dominant tension directions in the shared parameter space. It further provides a geometric interpretation of the...
