Unlike previous studies that simulated the formation of the first stars within a smaller cosmological boxsize of $\\sim 1-2$ Mpc, our work adopts initial conditions from the large-scale cosmological simulations, IllustrisTNG spanning $\\sim 50$ Mpc to study the formation of primordial clouds that give birth to the first stars.
