Description
It had been proposed [Qadir A., Tahir N., and Sakhi M., PRD 100, (2019)] that virial clouds “propped up” by the cosmic microwave background (CMB), and hence at that temperature, populate dark matter halos and may account for a significant fraction of the missing baryons. To understand the nature of these clouds, it is necessary to trace their evolution from the last scattering surface (LSS) at $z=1100$ to the present day. The first stage of this evolution, spanning the redshift range $1100 \geq z \geq 48$, was investigated in [Tahir, N., Qadir, A., Sakhi, M., and De Palois, F., EPJC, 81, 827 (2021)]. In the present work, we study the second stage of their evolution, from the formation of the first generation of stars $(z = 48)$ up to the epoch of their supernova explosions $(z = 10)$.
