The star formation -- AGN connection

Gas is needed both to form stars, and to fuel feedback from supermassive black holes ('AGN feedback').

Both star formation and AGN feedback can be enhanced following gas-rich galaxy mergers, with simulations predicting a delay between the peak in star formation and the peak in accretion onto the central black hole. Better understanding this delay can help inform observations of merging galaxies, which we can see only in one instant of their evolution.

In this project, you will measure the time between the peaks in star formation rate and black hole accretion rate in galaxies in a cosmological simulation following a merger. Is this delay time universal? Does it depend on the properties of the progenitor galaxies? How can the results be used to better understand observations of merging galaxies?
