Stellar mass–gas mass scaling relation for satellite galaxies at the final snapshot (z = 0.158) in the NEWHORIZON2 simulation. Satellite galaxies are categorized as either normal (f_gas > 0.01; blue circles) or gas deficient (f_gas < 0.01; downward red arrows). For comparison, the scaling relation of the NEWHORIZON2 central galaxies is shown as the blue contours. Gas-rich normal satellite galaxies closely follow the scaling relation of the central galaxies, while gas-deficient satellites are predominantly low-mass systems. The stellar mass distribution of the satellite sample is shown as a histogram at the top. The observed scaling relations from galaxies in the local Universe (purple dotted line) and in low-mass groups (pink dotted line) are overplotted, both showing similar trends to those of the NEWHORIZON2 central galaxies.
