Black holes, over a million times the mass of our Sun, lurk in the center of most massive galaxies. Fundamental questions in astrophysics about their nature are currently unanswered.
How are such massive compact objects formed?
What physical mechanisms are conducive to accretion on massive black hole?
What processes are driving the global evolution of Active Galactic Nuclei and star formation?
We are using observations (e.g., JWST, Euclid, HSC, ALMA) across the electromagnetic spectrum of deep and wide survey fields to characterize the underlying galaxy population (e.g., stellar mass, star formation rate, morphology) and identify those hosting actively accreting black holes, primarily through their optical and X-ray emission less susceptible to obscuration by dust. Our focus has been on disentangling observed influences over a range of scales from local to large-scale environments.
