Kind: research · Impact: medium

## In brief

- Fourteen years of Fermi telescope data reveal around 450 gamma-ray sources.
- The count roughly doubles the known objects in this energy range.
- About 15% of the newly found sources remain unidentified.

## Why it matters

The catalogue expands the known population of gamma-ray sources in a previously sparsely mapped energy range, giving astronomers more targets to study and more unidentified objects to classify.
