PROGRESS: Here's the DESI focal plane with 7 of the 10 petals installed. You are looking at the input end of 3,500 positioners! 📷 by Robert Besuner More info: In the foreground is one of the guiders. The red wedges are panels where the next petals will be inserted.

People often ask if AI will take over the Universe 🤪... That I don't know, but how about... Could AI discover what is in the Universe? With our new approach, the answer is YES! Led by ChangHoon Hahn Papers: arxiv.org/pdf/2211.00723… and arxiv.org/abs/2211.00660

Thanks, Shirley Ho! We can extract cosmological information about the Universe from the 3D distribution of Sloan Digital Sky Surveys BOSS galaxies! With #SimBIG, we can leverage simulations to extract significantly more information than current analytic approaches!
