The Manhattan Suite: Accelerated galaxy evolution in the early Universe

Astrophysics of Galaxies 2024-12-06 v2

Abstract

Observational advances have allowed the detection of galaxies, protoclusters, and galaxy clusters at higher and higher redshifts, opening a new view into extreme galaxy evolution. I present an argument that the high redshift, massive galaxies discovered over the last decade are really the most massive galaxies within protocluster-cores of galaxy clusters at z2z\sim2, and that they are the partial descendants of same galaxies discovered by JWST at z9z\sim9. To that end, I present The Manhattan Suite\textit{The Manhattan Suite}, a set of 100100 high resolution zoom-in simulations of the most massive galaxy clusters, out to 9Rvir9\,R_\mathrm{vir}, selected at z=2z = 2 from a (1.5cGpc)31.5\,\mathrm{cGpc})^3 parent volume, and simulated using the Simba\textit{Simba} model. Unlike other cluster suites, my selection at z=2z = 2 ensures that these systems are biased in a similar fashion to observations, in that they should be the brightest and the most massive by construction at z2z \gtrsim 2. I show that my sample is able to reproduce extremely star-bursting protoclusters such as SPT2349-56, high redshift galaxy clusters XLSSC122 and JKCS0249, and the wealth of massive (sometimes quenched) galaxies at z3z \gtrsim 3 and up to z9z \sim 9. I argue that these systems are intimately linked, and represent the same evolutionary history.
