Population of X-ray Sources in the Intermediate-Age Cluster NGC 3532: a Test Bed for Machine-Learning Classification

Steven Chen, Oleg Kargaltsev, Hui Yang +4

Open clusters are thought to be the birth place of most stars in the Galaxy. Thus, they are excellent laboratories for investigating stellar evolution, and X-ray properties of vari…

The Future of Gamma-Ray Experiments in the MeV-EeV Range

Kristi Engel, Jordan Goodman, Petra Huentemeyer +95

Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about par…
