I am currently an undergraduate researching Supernovae. We are doing some luminosity calculations using CIAO and HEASOFT which take anywhere between 7 to 13 hours for each remnant. To make the process quicker, I wrote a script that reduces that time to about 40 minutes for each remnant. One of my current professor's students (who graduated last year) wrote a script to divide a remnant into small boxes and do some measurements with it. Prof. Brian Schmidt wrote the code which automated the process of finding Type Ia supernovae. Is this a common trend? Are there any other examples that you can give me? I assume that it would be since a lot of Astronomy is data analysis which happens using computers.
