Galactic Center Radio Constraints on GammaRay Lines from Dark Matter Annihilation

From a channel Lumen includes in full: This is the official channel of Ohio State's Center for Cosmology and AstroParticle Physics. It consists almost entirely of hour-long public lectures by working scientists (Stern, Dalcanton, Carroll, Sobel, Markoff), memorial symposium science talks, and a research explainer. Transcripts confirm academic, education-first framing with no hype or entertainment hooks. The only non-teaching items are the brief opening-remarks clip and the rapid poster session, which the title patterns catch.

A 5-minute video from CCAPP OSU's catalogue; the title names its topic.
