Radial and halo mass scaling of gas outflows at z = 0. Upper row: Gas mass fraction in outflows, defined as the ratio of the outflowing gas mass over total gas mass in a given radial shell. Lower row: Mean velocity of outflows in a given radial shell. Left column: Halo mass scaling of outflows at fixed radius r = 5r_{200, GrO}. Right column: Radial scaling of outflows at fixed halo mass M₂₀₀ = 10¹³ h⁻¹ M_⊙. The averages are taken over 100 isolated halos in each mass bin between M₂₀₀∈(10¹³, 10¹⁵) h⁻¹ M_⊙, and the error bars denote the standard deviations. The colours stand for different FLAMINGO models.
