LONG-TERM TeV AND X-RAY OBSERVATIONS OF THE GAMMA-RAY BINARY HESS J0632+057
Bibliographic record
Abstract
HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations \nwith ground-based observatories in both the northern and southern hemispheres. Here we report on long-term \nobservations of HESS J0632+057 conducted with the Very Energetic Radiation Imaging Telescope Array System \nand High Energy Stereoscopic System Cherenkov telescopes and the X-ray satellite Swift, spanning a time range \nfrom 2004 to 2012 and covering most of the system’s orbit. The very-high-energy (VHE) emission is found to be \nvariable and is correlated with that at X-ray energies. An orbital period of 315+6 \n−4 days is derived from the X-ray \ndata set, which is compatible with previous results, P = (321 ± 5) days. The VHE light curve shows a distinct \nmaximum at orbital phases close to 0.3, or about 100 days after periastron passage, which coincides with the \nperiodic enhancement of the X-ray emission. Furthermore, the analysis of the TeV data shows for the first time a \nstatistically significant (>6.5σ) detection at orbital phases 0.6–0.9. The obtained gamma-ray and X-ray light curves \nand the correlation of the source emission at these two energy bands are discussed in the context of the recent \nephemeris obtained for the system. Our results are compared to those reported for other gamma-ray binaries

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
