Mass proxy quality of massive halo properties in the illustrisTNG and flamingo simulations: I. Hot gas
We examine scale and redshift dependence of mass-property relations (MPRs) for five hot gas properties of two large group- bservationsand cluster-scale halo samples realized by the Illustris tng, TNG-Cluster, and FLAMINGO cosmological hydrodynamical simulations. For intrinsic properties of (i) hot g...

| Zusammenfassung: | We examine scale and redshift dependence of mass-property relations (MPRs) for five hot gas properties of two large group- bservationsand cluster-scale halo samples realized by the Illustris tng, TNG-Cluster, and FLAMINGO cosmological hydrodynamical simulations. For intrinsic properties of (i) hot gas mass (Mgas), (ii) spectroscopic-like temperature (Tsl), (iii) soft-band X-ray luminosity (LX), and (iv) X-ray (YX), and (v) Sunyaev-Zel’dovich (YSZ) thermal energies, we use MPR parameters to infer mass proxy quality (MPQ) - the implied scatter in total halo mass conditioned on a property - for haloes with M500 ≥ 10 13 M}_\odot$ at redshifts, |
