Location

The meeting will be in San Cristóbal de La Laguna in Tenerife, hosted at the Instituto de Astrofísica de Canarias • IAC .

Programme

The meeting will focus on four themes: (1) modelling, (2) measuring and (3) simulating the Universe, and the (4) infrastructure work required for it. Below is a draft program summarising the talks, confirmed speakers, material we expect to cover, and split between talks and discussion.
