# Young magnetars born in core-collapse supernovae of massive stars.

Young magnetars born in core-collapse supernovae of massive stars.

## Where it stands

**Most likely** Its tests partly supported it: three pieces of evidence for, two against. It needs two reviews to be accepted.

## What it predicts

- Hosts are star-forming galaxies and bursts lie on or near star-forming regions.
- The FRB rate tracks the cosmic star-formation history.
- Emission shows magnetospheric signatures (polarisation swings, small emitting regions).

## What would rule it out

- A large localised sample in which one-off bursts are not concentrated in star-forming hosts or regions, or a redshift distribution clearly delayed from star formation.
