Abstract

Combining rich multiwavelength data sets and spectral energy distribution (SED) fitting, we explore the cosmic history of stellar mass assembly and the growth of super massive black holes from the onset of galaxy formation. This was possible by combining ground-based observations with those of both the Hubble and James Webb Space Telescopes (JWST) to probe the among the first galaxies to ever exist. JWST has opened the door to the frontier of the early Universe that in combination with existing ground based efforts has facilitated the census of mass and energy in galaxies over at least 99% of cosmic time.
