What I’ve written:
- A paper using spectra and imaging from space to reconstruct the evolution of four
galaxies’ masses and internal structures over time.
- A paper asking whether galaxies need to shrink to turn red, or if they’re just born
- A paper on the surprising accuracy of our very simple model of galaxy
evolution…but also everyone else’s (and what that means for my subfield).
- A paper on how relevant the evolution of galaxy populations is to the evolution of
- A paper on how galaxies are made of two pieces (and that this fact is important).
- A paper on how cosmological models predict too many small galaxies (except
maybe when they’re very isolated).
- A paper on how galaxies “cycle” through different modes of star formation (unless
something stops them).
What I’ve talked about: (PDFs best viewed as slide shows)
- A talk I gave at a conference in Perth on some fundamental challenges to learning
the biographies of individual galaxies. (This one was tough.)
- A filmed talk(!) I gave at the Carnegie Observatories about the crazy challenges of
figuring out how galaxies evolve using astronomical data, and some ways we might
make progress towards a Final Theory.
- A talk I gave at a special workshop in Holland dedicated to understanding why
galaxies go from being blue to being red.
- A talk I gave at another special workshop in Holland dedicated to finding deeper
meaning (if there is one) in the fact that heavier galaxies form more stars every
year than lighter ones.
- A talk I gave to the Riverside and Ventura Country Astronomical Societies on the
similarities between galaxies’ and people’s lives.
- A talk I gave in Italy describing a different way to think about how red and blue
galaxies got their colors.
- A talk I gave at UCDavis about what will ultimately be the upshot of my thesis.
- A talk I gave in Pasadena about how a planned space telescope will revolutionize
our understanding of the relationship between a galaxy’s environment and its
- A talk I gave at Alan Dressler’s (my collaborator and mentor at Carnegie) festschrift;
Zion National Park, September 2014.
- The context of this paper, at The Carnegie Observatories; a more technical
description of my research interests.
- A really cool lab I did with my Space Explorers where the students (and the teacher)
are the experiment. If you’re an instructor, here’s a useful companion worksheet to
go along with/help you plan the activity.
