	abstract = {We investigate galaxy conformity using the \{{\textbackslash}sc Mufasa\}{\textbackslash} cosmological hydrodynamical simulation, which uses a heuristic halo mass-based prescription to quench central galaxies. We show that satellite galaxies are broadly consistent with observations, showing a bimodal distribution in colour with radius, albeit with too many low-mass quenched satellites. In \{{\textbackslash}sc Mufasa\}, galaxy conformity is evident in previously observed properties such as colour, specific star formation rate, and \{{\textbackslash}sc Hi\}{\textbackslash} content, as well as in environment, stellar age, H\$\_2\$ content, and metallicity. We introduce quantifying conformity using a new measure \$\{{\textbackslash}cal S\}(R)\$, and show that low-mass haloes have weak conformity extending to large projected radii \$R\$ in all properties, while high-mass haloes have strong conformity that diminishes rapidly with \$R\$ and disappears at \$R{\textbackslash}ga 1\${\textasciitilde}Mpc. \$\{{\textbackslash}cal S\}(R)\$ is strongest for environment in low-mass haloes, and sSFR (or colour) in high-mass haloes, and is dominated by one-halo conformity with the exception of \{{\textbackslash}sc Mufasa\}{\textbackslash} in small haloes. Metallicity shows a curious anti-conformity in massive haloes. Tracking the evolution of conformity for \$z=0\$ galaxies back in time shows that conformity generally emerges as a late-time phenomenon. However, for fixed halo mass bins, conformity is fairly constant with redshift out to \$z{\textbackslash}ga 2\$. These trends are consistent with the idea that strong conformity only emerges once haloes grow above \{{\textbackslash}sc Mufasa\}'s quenching mass scale of \${\textbackslash}sim 10{\textasciicircum}\{12\}M\_{\textbackslash}odot\$. A quantitative measure of conformity in various properties, along with its evolution, thus represents a new and stringent test of the impact of quenching on environment within current galaxy formation models.},
