Direct collapse black holes (DCBHs) are currently the leading contenders for
the origins of the first quasars in the universe, over 300 of which have now
been found at $z >$ 6. But the birth of a DCBH in an atomically-cooling halo
does not by itself guarantee it will become a quasar by $z sim$ 7, the halo
must also be located in cold accretion flows or later merge with a series of
other gas-rich halos capable of fueling the BH’s rapid growth. Here, we present
near infrared luminosities for DCBHs born in cold accretion flows in which they
are destined to grow to 10$^9$ $M_{odot}$ by $z sim$ 7. Our observables,
which are derived from cosmological simulations with radiation hydrodynamics
with Enzo, reveal that DCBHs could be found by the James Webb Space Telescope
at $z lesssim$ 20 and strongly-lensed DCBHs could be found in future
wide-field surveys by Euclid and the Wide-Field Infrared Space Telescope at $z
lesssim$ 15.
