Finding the infant massive black holes in the early universe

This work combines state-of-the art cosmological simulation with a radiative transfer post-processing analysis tool.

Six boxes, three on top, whowing the supernovae burst phase in purple, red, green, blue and black

Halo during the beginning of the supernovae burst phase (5.3 Myr after the formation of the DCBH). Top row: Integral of density-weighted mean density (left), density-weighted mean temperature (middle), and density-weighted mean metallicity (right). Bottom row: Integrated total emission (left), scattering per unit area (middle), and ionized hydrogen fraction (right). The location of the DCBH is shown as a black circle in the top right plot. The first supernovae after the star-formation burst are seen heating the CGM 4 Myr after the insertion of the DCBH.
