This cartoon is part of the DES Y3 #Darkbites social media series. It was drawn to illustrate a paper about the method used to check for tension between cosmological constraints made with different datasets. The paper was led by Pablo Lemos and Marco Raveri and is titled, “Assessing tension metrics with Dark Energy Survey and Planck data.” (arXiv:2012.09554)

The post’s associated text was:

Different measurements of the large-scale Universe give us pieces of a big picture describing its properties. If DES results don’t match what we expect from other observations, we might have discovered something new!

Here’s a link to the post. The twitter thread of the Y3 Darkbites posts begins here. The cartoons also being shared on the DES facebook and instagram pages.

I’ve also made a version of this cartoon with the labels in Spanish: alt="Same cartoon as above, but with the model and data labels on the photos translated into Spanish."
