The large-scale distribution of ionized metals in IllustrisTNG

We study the intrinsic large-scale distribution and evolution of seven ionized metals in IllustrisTNG magneto-hydrodynamical cosmological simulation. focus on fractions C\,\textsc{ii}, C\,\textsc{iv}, Mg\,\textsc{ii}, N\,\textsc{v}, Ne\,\textsc{viii}, O\,\textsc{vi}, Si\,\textsc{iv} different cosmic web structures (filaments, haloes, voids) gas phases (warm-hot intergalactic medium WHIM, hot, diffuse, condensed gas) from $z=6$ to $z=0$. Our analysis provides a new perspective baryons across time while offering hints context well-known missing problem. The components are here identified using local comoving dark matter density, which simple but effective way mapping large scales. results show that C\,\textsc{ii} Mg\,\textsc{ii} mostly located inside haloes high-density low-temperature star-forming regions ($\rho_{\rm gas}/\bar{\rho}_{\rm bar}\gtrsim10^3$, ${\rm T}\lesssim10^{5}$~K). C\,\textsc{iv} present similar their mass filaments time. In particular, budgets phase T}\lesssim10^{5}$~K) driven by cooling star formation with peak at $z\sim2$. Finally, our confirm N\,\textsc{v} good tracers warm/hot low-density low redshift bar}\lesssim10^3$, T}\gtrsim10^{5}$~K), likely contain most Universe.
