FOREVER22: Insights into star formation and clustering properties of protoclusters from simulations and JWST

Kana Morokuma-Matsui, Hidenobu Yajima, Makito Abe

Using cosmological hydrodynamic simulations with radiative transfer, we investigate star formation and overdensity () in Coma-type cluster progenitors from to 6. Our simu…

FOREVER22: Gas and metal outflow from massive galaxies in protocluster regions

Naoki Harada, Hidenobu Yajima, Makito Abe

We study gas and metal outflow from massive galaxies in protocluster regions at by using the results of the FOREVER22 simulation project. Our simulations contain massive ha…
