This past week, we skyped with one of our collaborators. We revisited a program that we began to write last semester. The purpose of the code is to recreate the figures from Kim+2016 so we can identify the filaments around Virgo using the same criteria they did. In particular, we want to create a 3-D spatial plot of the region around Virgo, and SGZ vs. SGX plots with cuts in certain SGY regions. Our plots look a little similar to the Kim+2016 plots, but our SGY values are off by approximately 16 Mpc, which is how far away Virgo is from us. This is strange, so we are looking into supergalactic coordinates to try to ensure that we are using them correctly. We are doing this by looking at all of the papers that Kim+2016 cited in reference to the flow model that they used. The Kim+2016 paper is incredibly short, so unfortunately it is not well documented. My plans for this next week are to go through these papers, and to alter our program based on the criteria specified in them to see if our plots look more similar to the Kim+2016 figures. It's going to be a lot of trial and error work, but hopefully we can make some progress.
