Description
The evolution of galaxies is linked to the growth of large scale structure in ways that are still poorly understood. This is, in part, because deep, wide-field spectroscopy is essential for associating individual galaxies with specific environments. I will summarize results from the GOGREEN imaging and spectroscopic survey of 21 galaxy clusters at 1<z<1.5. While we do find evidence that accretion onto massive structures plays a role in quenching star formation for low mass galaxies (M<1e10), it appears that the more massive galaxies ceased forming stars long before their arrival in the cluster. I will conclude by looking forward to what we can learn from protoclusters at 2<z<3, and from the next generation of facilities like the Maunakea Spectroscopic Explorer (MSE).
