DESI DR1
Legacy/superseded pipeline record retained for methodology and archive context. Historical candidate counts and classifications are unreconciled, are not current discovery results, and do not provide evidence for a bounce.
Key findings
01 Historical, unreconciled pipeline output — HISTORICAL / UNRECONCILED: 195,829 pipeline candidate flags from 22.5M spectra (0.87%)
02 Historical, unreconciled pipeline output — 2,145 pass SNR filter, 120 gold (>5σ)
03 Historical, unreconciled pipeline output — 1,127 not in SIMBAD or NED (52.5% uncataloged)
04 Historical, unreconciled pipeline output — 10 taxonomy families: 76 AGN, 27 post-starburst, 363 blue compact
05 Historical, unreconciled pipeline output — 16 NEOWISE IR-variable anomalies incl. z=5.65 QSO
06 Historical, unreconciled pipeline output — Central 9.4% multi-tracer fNL forecast (consistent with no improvement at <1σ)
07 Historical, unreconciled pipeline output — Injection/recovery: 0% false positive, 10–1,377x enrichment
