Abstract
In the local universe, black hole masses have been inferred from the observed
increase in the velocities of stars at the centres of their host galaxies. So
far, masses of supermassive black holes in the early universe have only been
inferred indirectly, using relationships calibrated to their locally observed
counterparts. Here, we use the latest observational constraints on the
evolution of stellar masses in galaxies to predict that the region of influence
of a central supermassive black hole at the epochs where the first galaxies
were formed is $directly \ resolvable$ by current and upcoming
telescopes. Such measurements will usher in a new era of discoveries unraveling
the formation of the first supermassive black holes based on subarcsecond-scale
spectroscopy with the $ALMA$, $JWST$ and the $SKA$. The measured mass
distribution of black holes will allow forecasting of the future detection of
gravitational waves from the earliest black hole mergers.
