Group photo at the LEM workshop, 03/01/2023 — Cambridge, MA

This group photo shows a small subset of the LEM team and omits, regrettably, those who participated in this workshop remotely and other team members who were unable to participate in this particular meeting at all

Credit: The LEM team is grateful for the beautiful images and videos prepared by the IllustrisTNG and EAGLE teams. LEM mocks and simulations shown on the website were also presented in the LEM White Paper. The website was designed by Akos Bogdan.
