Relation j_i − m_i medians for the stellar (red dashed lines) and gaseous (green dashed lines) disc components, the stellar spheroidal components (pink dashed lines), the total stellar component (blue line), and the total baryonic component (black lines). The solid black line represents the relation in the case of angular momentum conservation. The stellar and gas disc components are consistent with angular momentum conservation, while the spheroidal components determine a relation with a similar slope but offset by a constant factor suggesting that spheroids have lost a similar fraction of angular momentum with respect to the total angular momentum of their virial haloes. The relation has been estimated for z = 0 (upper panels, in the right panel we include the scatter data for the stellar disc component), and for z = 1 and z = 2 (bottom panels, left and right, respectively), and shows similar trends.
