Event Information:

A key open question in extragalactic astronomy is understanding the processes driving the build-up and quenching of massive galaxies — specifically the role of AGN and environment therein. As an overview of my recent research activities, I will present several projects that all help inform the above question.  I will address some of the issues with going from observed properties to physical properties and a possible pathway to scaling this up to the sample sizes in the billions that are on our horizon now.  In this context, I will touch upon the issue of fully accounting for dust obscured star-formation and AGN activity. Lastly, I will discuss how we assess a galaxy's environment with photometric data as well as prospects for doing so much better with the upcoming PFS galaxy evolution spectroscopic survey.
