Adam Muzzin's research focusses on galaxy formation and evolution, particularly the high-redshift universe.
The most massive galaxies in the universe are rare, but because of this, their formation history imposes some of the strongest constraints on our models of galaxy formation. In the local universe, massive galaxies like M87 appear relatively dull, with elliptical morphologies, old stars, and little ongoing star formation. For decades, archeological studies predicted that most of the action during these galaxies’ formation must have occurred at much higher redshift (z > 2). With the first deep and wide field surveys of the near infrared sky coming online, we can now directly observe the progenitors of local massive galaxies as they are forming. I will show state-of-the-art observations of this process up to z ~ 4, where we are finding that the early stages of massive galaxy formation are in fact extremely dynamic, with huge bursts of dust-obscured star formation, ubiquitous AGN activity, and significant structural transformations. I will also discuss what we are learning at z ~ 6-7 from ongoing deep/wide surveys such as UltraVISTA, and what we expect to learn in the JWST era, when we may be able to observe the process of massive galaxy formation right out to its initial stages at z ~ 10-20.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
