Also intriguing is the report in yesterday's Nature that some FRB
sources appear to repeat, which apparently means they are single
ultracompact objects rather than mergers.

Also in Science yesterday is a nice article showing cosmic ray
evidence for an unidentified LOCAL population of compact cosmic ray
accelerators.

One is inclined to ask if there is a large but previously unidentified
population of very high energy ultracompact sources that has yet to be
fully discovered and characterized.
