Right now, I'm working on classifying the orbital structure of triaxial galaxies. For an update on this research,

my collaborators up to date on our work, so you may not find this very useful
if you're looking for a primer on the topic.)
My thesis simulated the stellar dynamics of elliptical galaxy mergers.
We think that it's not unusual for galaxies to collide, or merge,
with other galaxies at somepoint in their lifetimes, sometimes
shredding one of the interacting galaxies in the process.
The whole merger takes far too long to observe directly, but we can
model mergers with computer simulations. That's what I do: I build
fake galaxies on my computer and smash them together. Well ok, I really only get to observe when people let me tag along,
or when they can't make the run themselves, but I've racked up
a surprising amount of telescope time for a simulationist!
Movie of the small galaxy on a head-on merger
with a galaxy that is 10 times more massive.
Movie of the small galaxy during a head-on merger
with a galaxy that is 10 times more massive, and the host to a supermassive
black hole. It's hard not to notice that
this time, the small galaxy is totally disrupted. The last frame shows
the distribution of the debris.
Movie of the small galaxy on
a more circular encounter with a galaxy that is 100 times more massive. Again,
notice that the small galaxy is destroyed.
Movie of the small galaxy on a more circular
encounter with a galaxy that is 10 times more massive. This time, the
small galaxy is not destroyed and instead forms a disk. Find out more about
these results from the thesis.
