UWM Physics professor David Kaplan worked with colleagues at the University of Sydney to discover an unusual radio source in the direction of the Galactic Center. Using the ASKAP radio telescope as part of the Variables and Slow Transients (VAST) survey, they identified a variable, polarized radio source that confounds typical models for such sources (like a pulsar or a flaring star).
Kaplan and colleagues wrote about their experience for the Conversation.
