Table 3.
Number of PWNe above instrument detection thresholds for each evolutionary phase.
| Phase | Count / Total | Fraction (%) | CTAO | H.E.S.S | HAWC | SWGO | WCDA | KM2A |
|---|---|---|---|---|---|---|---|---|
| Free expansion | 153 ± 7/1600 | 9.5 | 49 ± 4 | 18 ± 2 | 5 ± 1 | 42 ± 4 | 12 ± 2 | 11 ± 2 |
| Compressing | 192 ± 8/1600 | 12 | 87 ± 5 | 32 ± 3 | 11 ± 2 | 66 ± 5 | 22 ± 3 | 6 ± 1 |
| Post-compression | 1255 ± 10/1600 | 78.4 | 36 ± 3 | 2 ± 1 | 1 ± 1 | 9 ± 2 | 1 ± 1 | 0 ± 0 |
Notes. The table reports the mean number of detectable sources across 1000 realizations, together with the corresponding 1σ uncertainty. In this table, the “fraction” was computed as the mean number of sources in each evolutionary stage relative to a population of 1600 PWNe.
