Minicourse on Testing the Cosmological Principle

June 16 – 17, 2025

ICTP-SAIFR, São Paulo, Brazil

Venue: IFT-UNESP, auditorium

Home

The cosmological principle stands as one of the most successful working assumptions in modern physics. In a statistical sense, the Universe does indeed appear homogeneous and isotropic on sufficiently large scales. However,  the guiding principle in the era of precision cosmology is: know your biases.
In this mini-course, we will:
  • Assess the extent to which the cosmological principle may bias our cosmological inference;
  • Explore the theoretical frameworks developed to relax or go beyond this assumption;
  • Examine how cutting-edge cosmological observations can inform a more accurate description of the metric of the local Universe.

There is no registration fee.
