The current generation of cosmological surveys is mapping vast volumes of the Universe with exquisite precision, delivering high-precision cosmological measurements and constraints. This advance demands a commensurate advance in theoretical precision. To fully exploit this wealth of data, it is essential to account for general relativistic effects in the modelling of cosmological observables.

This conference continues the established series of meetings on GR Effects in Cosmology, following previous editions in Cape Town (2016), Zurich (2017), Sexten (2018), Zurich (2019), Porto (2022), Geneva
