Abstract We describe a mechanism of the primordial black holes formation that can explain the existence of a population of supermassive black holes in galactic bulges. The mechanism is based on the formation of black holes from closed domain walls. The origin of such domain walls could be a result of the evolution of an effectively massless scalar field during inflation. The initial non-equilibrium distribution of the scalar field imposed by background de Sitter fluctuations gives rise to the spectrum of black holes, which covers a wide range of masses—from superheavy ones down to deeply subsolar. The primordial black holes of smaller masses are concentrated around the most massive ones within a fractal-like cluster.

• Formation of supermassive black holes (2010, background): “The masses of primordial black holes formed in the above mentioned processes range roughly from the Planck Mass (black holes formed at the Planck epoch) to M (black holes formed at the QCD phase transition) up to 105 M (Khlopov et al, 2005).”
• Primordial black holes as generators of cosmic structures (2018, background): “…the possibility that quasars are seen at high redshift because they are powered by SMBHs which formed before galaxies, In this case, they could be primordial (Bean & Magueijo 2002; Duechting 2004; Khlopov et al. 2005; Clesse & Garcia-Bellido 2015) and this would lead to three possible scenarios.”
• Effect of Primordial Black Holes on the Cosmic Microwave Background and Cosmological Parameter Estimates (2007, background): “PBH growth and “clothing” dark halo PBHs more massive than 105 M⊙ may only exist if substantial accretion takes place after their formation or if many PBHs which form in a cluster merge into a larger one (Meszaros 1975a; Khlopov et al. 2005; Chisholm 2006).”
• Primordial black hole and wormhole formation by domain walls (2016, result): “Although the present work is motivated by the scenario where domain walls nucleate by quantum tunneling during inflation, some of our results may also be useful in scenarios where the sites of domain walls after inflation are determined by quantum diffusion of light fields during inflation [35, 36].”
• Evolution of cosmological perturbations in Bose–Einstein condensate dark matter (2011, methodology): “…also intensively been used to model galactic dark matter (Lee & Koh 1996; Nucamendi et al. 2000; Matos & Guzman 2001; Mielke & Schunk 2002; Arbey et al. 2003; Fuchs & Mielke 2004; Hernández et al. 2004; Giannios 2005; Khlopov et al. 2005; Bernal & Guzman 2006; Arbey 2006, 2008; Briscese 2011).”
