Balloon astrophysics in Canada over the next decade
Bibliographic record
Abstract
Stratospheric balloons offer near space observing conditions for a small fraction of the cost of an equivalent satellite. Balloon telescopes can make cutting-edge astrophysical observations, while also providing a platform to advance the technology readiness level of key systems for future space missions. Furthermore, balloon astronomy offers outstanding training opportunities. Typical experiment timeframes allow graduate students to play a key role in the instrument design, field campaigns, and scientific data analysis. In this white paper we will overview Canadian involvement in balloon astrophysics and outline the priorities of the balloon astronomy community for the coming decade. These priorities are: continued stable funding for the development of balloon-borne experiments, competitions for larger funding awards that would support the building of balloon-borne observatories or equivalent particle astrophysics experiments, support for PIs to access existing pointing platforms and balloon gondola technology, and opportunities for long duration conventional balloon and super-pressure balloon flights.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
