Halos baryonic properties

Catalog of the global baryonic properties of the FOF halos in R200

Average properties as a function of T200 (to be compared with Rasera&Teyssier 2006 - same scale and units): symbols are MN results and lines are analytical model predictions.

Efficiency of SF as a function of T200

Specific SFR as a function of T200

Fraction of stars as a function of T200

Seeing the 3 precedent graphs, it seems that large halos form stars more efficiently than smaller ones. I don’t know why for the moment. Does anybody have an idea? Yann.

Fraction of cold gas as a function of T200

Fraction of hot gas as a function of T200

Fraction of baryons as a function of T200

Note that the baryon fraction is really close to the universal one and the minimal halo mass for baryons to collapse in dark matter potential well is well predicted by the model.
