I really like mathematics, physics, and programming/simulation/computer modeling. I want to try my hand at physics research. However, I don't want to build sensors or spend most of my time building experiments. I really like coding and data analysis. I am thinking that astrophysics research might be my cup of tea, but I am also interested in plasma/nuclear, quantum computing, and HEP, though of course it is impossible to know without trying things and learning more first. What areas of research are almost purely computational and won't require me to spend months building an experiment? I don't mind building for small amounts of time, but in general it isn't what I am passionate about.
