Analyzing Thermal Spectra with Machine Learning

Editor's note: Astrobites is a graduate-student-run organization that digests astrophysical literature for undergraduate students. We hope you enjoy this post from astrobites; the original can be viewed at astrobites.org. Galaxy clusters are among the largest gravitationally bound structures in the universe. One of their defining characteristics is that they tend to be embedded within a large reservoir of superheated gas, known as the intracluster medium (ICM). With temperatures up to 108 Kelvin, the ICM is a strong emitter of X-ray radiation.
