Event Information:

Studying the host galaxies of high-redshift quasars provides vital insights into the early growth of supermassive black holes and the black hole—galaxy connection. The launch of JWST will start a new era in this field, providing the opportunity to observe the stellar components of these host galaxies for the first time. Here I will present an analysis of the hosts of z=7 quasars in the BlueTides cosmological hydrodynamical simulation. I will show how we have used the BlueTides simulation in combination with an observational quasar subtraction technique to make comprehensive predictions for photometric observations of these host galaxies with JWST. We analysed the success rates of detecting the host galaxies with various instruments, filters and exposure times, and studied which quasar and host properties are more likely to result in successful detections. This work guided our Cycle 1 JWST observations, which I will also discuss.
