DESI Legacy Galaxy Chirality Catalog
This dataset accompanies the current Paper IV manuscript, An Observed-Label Chirality-Dipole Null in 949,584 High-Confidence DESI Spirals and an 8.5-Million-Galaxy Catalog.
The primary high-confidence observed-label statistic is consistent with zero under fixed-occupancy label randomization (z=0.7053169638, one-sided empirical-rank p=0.2246775322). This is not a calibrated true-spin, physical-amplitude, or primordial-parity bound.… See the full description on the dataset page: https://huggingface.co/datasets/bamfai/galaxy-chirality-catalog.index-cards-cas-galapagos-stewart-specimens
Alban Stewart's Galápagos Expedition Specimen Cards (CAS Archives, 1905–1906)
1,059 specimen index cards from the California Academy of Sciences Archives,
documenting Alban Stewart's botanical specimens collected on the 1905–1906

Galaxy Zoo 10 × Legacy Survey DR9
Dataset Summary
This dataset contains 7,864 galaxies from the
Galaxy Zoo 10 morphology catalogue,
cross-matched with Legacy Survey DR9 imaging.
Each sample includes:
A 4-channel 160×160 pixel image (Legacy Survey grz + WISE W1),
stored as raw calibrated flux (nanomaggies). Normalization is left to the training pipeline.
10-class morphology label (gz10_label, gz10_class_name)
Photometric scalars: flux densities (g, r, i, z, W1… See the full description on the dataset page: https://huggingface.co/datasets/OneAstronomy/galaxyzoo10_legacysurvey.galaxy-vit-gz-desi-dirichlet-predictions
Galaxy-ViT — GZ DESI Dirichlet predictions
Per-galaxy Dirichlet-Multinomial concentration parameters (α) for the
10-question / 34-answer Galaxy Zoo DESI decision tree, predicted by a
Zoobot ConvNeXt-nano encoder finetuned with a Dirichlet-Multinomial
head on the DR8 subset of the
