Extended Data Fig. 7: Relation between BH growth and halo properties.
From: The growth of light seed black holes in the early Universe
a: We show the final masses of BHs (Mf) as a function of its host halo mass. The simulations L13, L14, L15 and L15_BHFB are coloured red, blue, violet and yellow respectively. The dots show BHs that accreted more than 0.1 M⊙ and crosses focus on BHs that accreted more than their initial mass (Mi). We see no correlation between the two, suggesting that the halo does not need to be special in order for BHs to grow. b: We see a similar result when comparing the final masses with surface density of gas surrounding the BHs. However, we are incomplete in sampling larger halo masses and it is possible, even likely, that more massive halos would support additional growth and will also likely support the growth of LSBHs which have already experienced previous growth episodes.
