We propose to obtain WFC3/IR grism spectrocopy of our most robust sample of z>7 active galactic nuclei (AGN), selected from the most extensive X-ray and multiband surveys to date, drawing from both GOODS and COSMOS. These sources are the most robust z>7 candidate AGN that have been selected from any surveys to date, and represent our best opportunity to understand the formation and growth of black holes, and their role in galaxy evolution, within the first 800 Myr of cosmic time. A key mystery in our understanding of black hole growth is how they are able to grow so rapidly by z~6.4, which is the highest redshift for any spectroscopically confirmed AGN to date. Extensive ground-based NIR spectroscopic efforts on 8-10m telescopes to extend this redshift frontier to more distant AGN have so far proved fruitless, predominantly limited by the ground-based IR sky and the faintness of these sources. The unique gains afforded by WFC3/IR now provide us with the ability to open up this piece of parameter space, crucial to understanding how these sources form and evolve. We will also search for signatures of star formation that may be occurring in conjunction with the black hole feeding phase, which is of particular importance in the context of scenarios that invoke rapid accretion-driven black growth at these early epochs. Hence, this program will provide crucial information on our understanding of the formation and accretion processes associated with black holes in the very early universe, and how the relationships between black holes and galaxies are set in place that persist throughout the rest of cosmic time.

We will obtain NIR spectroscopy on each of our sources using WFC3/IR with the G102 and G141 grisms, to provide the most complete wavelength coverage possible in order to characterize their continuum and line emission, as well as enabling us to place meaningful upper limits on the line fluxes if these are not detected. We would observe each source at 2 different position angles, in order to provide a robust comparison of the spectra to enable us to definitively identify real features and reject spurious ones, as well as enabling possible coaddition of the resulting spectra, together with a short image (2-3 minutes) in F140W to provide a zero-order image that will improve the accuracy of the grism wavelength calibration.
