Dissecting the different sources of gas that seed the condensation of cold clouds out of the hot halo at z ∼ 0. On short timescales (≲500 Myr), the dissolution of past clouds into the hot phase, and the subsequent mixing, is the primary source, and it is also potentially stirred by outflows from the central galaxy into the CGM. Transitioning out into previous cosmic epochs as early as z ∼ 2 (t_lookback ∼ 10.5 Gyr), the mass giving rise to these seeds was predominantly smoothly accreted from the IGM into the halo (∼85%), while clumpy accretion through satellites contributes the remaining ∼15%.
