  1. 38. An Introduction to Some Cosmological Observables: from Inflation and Gravitational Waves to non-Gaussianity
    Nicola Bartolo (University of Padova)
    13/09/2023, 14:30

    In this talk I will provide a brief overview of some key words in the standard dictionary used in Cosmology, including some of the basic statistical tools to investigate various cosmological processes (focusing in particular on the so called Inflationary phase during the Early Universe and the generation of primordial gravitational waves). I will focus on the physics behind some of these...

  2. 37. The non-Gaussian Universe: a Challenge in Cosmological Data Analysis
    Michele Liguori (University of Padova)
    13/09/2023, 15:15

    One of the main goals of observational cosmology is the measurement of cosmological parameters, using the Cosmic Microwave Background (CMB) or the galaxy distribution 2-point function (power spectrum). This procedure would optimally extract all cosmological information if the CMB and galaxy density fields were perfectly Gaussian. Non-Gaussian features are however imprinted in these fields,...

  3. 42. Non-Gaussian Statistics and Non-Gaussian Tensions
    Marco Raveri (University of Genova)
    14/09/2023, 11:00

    I will review cosmological results obtained using non-Gaussian statistics with the Dark Energy Survey's (DES) latest data release. This will allow us to discuss statistical methods to probe discrepancies between cosmological data, without assumptions of Gaussianity in data and parameter space. I will show the worked examples of cosmological constraints from moments and peaks of the lensing...

  4. 46. Statistical Analysis and Exploitation of Sky Maps in Cosmic Microwave Background Observations
    Carlo Baccigalupi (International School for Advanced Studies)
    14/09/2023, 11:45

    We focus on the statistical properties of cosmological processes appearing in CMB anisotropies, as well on the associated aspects of Data Analysis. We consider the total intensity of the large fields observed by Planck and the associated constraints of the statistics of perturbations in the Early Universe, as well as the polarization measurements from operating and future probes looking in...
