Webb22 mars 2024 · This definition is used to calculate Γ 200m, Tdyn. We calculate individual mass accretion histories by normalizing M 200m of haloes at each redshift by their maximum mass at any epoch, M peak . In addition to this ‘mass history’, we also consider the ‘accretion history’ (Δ M / M peak )/Δ t dyn, 200m , the change per time of M 200m / M … Webbtheoretical meaning: 1. based on the ideas that relate to a subject, not the practical uses of that subject: 2. related….
