Welcome to my website! Here you can find general information about myself and my research, my blog (where I post intermittent updates on my research), as well as some pictures of the things that I ...

My first paper on dust evolution in outflows is out! In this paper, we used idealized simulations of individual dusty clouds in hot galactic winds to understand how sputtering affects dust in these...

When simulating dust, a major simplification in modeling can be made through assumptions about dust dynamics. Dust dynamics (which aren’t straightforward to calculate in Eulerian hydrodynamics simu...

I’m writing this post to help me learn some basics of shocks in fluid dynamics. It’s based on the book The Physics of Fluids and Plasmas by Arnab Rai Choudhuri. In fluid dynamics, a shock wave is ...

Overview To understand how dust is transported in galactic winds, I’ve been thinking about the primary mechanism that destroys dust at high gas temperatures in galaxies, sputtering. In very simpl...

The cloud crushing time is given by: $t_{cc}=\frac{\chi^{1/2}a_0}{v_b}.$ So, for a cloud of radius $a_0=0.1~\text{kpc}$, the cloud crushing times are: $\chi$ Physical Scenario...

Gas Temp $n=0.001~\text{cm}^{-3}$ $n=0.01~\text{cm}^{-3}$ $n=0.1~\text{cm}^{-3}$ $n=1~\text{cm}^{-3}$ $10^1~\text{K}$ $1.8\times10...

Simulating Dusty Clouds With Cholla Cloud-Wind Dynamics The dynamics of an interaction between a cool, dense, spherical cloud and a warmer or hot planar shock is a well-studied problem. The semina...

Visualizing Photometric Data As an assignment in my graduate galaxies course this spring, I was tasked with making a visualization of some sort of astronomical data or concept using an interactive ...

Background I am working on adding a dust model to the grid-based Cholla hydrodynamics code. Cholla currently uses its hydro capabilities to model gas, which is the primary fluid component of galaxi...
