For those who are relatively new to reading my work, here’s a little bit of background information in the event you haven’t seen my previous posts on this topic.
This year, I’ve decided to take on the challenge of wrangling with Dark Energy Spectroscopic Instrument data again. This time, instead of the Early Data Release, which contains pruned and polished data, I’m using the full Data Release 1 which was released in April of 2025, just a month before I presented my EDR results at the National Junior Science and Humanities Symposium. The main difference between the EDR and DR1 is the amount of data available, where I now have nearly 10 times as much data to work with.
I’ve finally got around to getting the correlation figured out, and I’ve run a best fit model for the data I have currently. The peak is a little higher than expected, but this is probably because of redshift distortions that I haven’t corrected for yet.
The result is definitely promising, and I think this was a pretty nice bonus Christmas present. I’m looking to compute a covariance matrix for my results and finally finishing my project soon.
