camels-cosmoGrid-z0 is a cosmology dataset subset derived from the CAMELS Multifield Dataset, focusing on the matter density grid at redshift z = 0.
This dataset is suitable for:
Research on cosmic structure formation
Training machine learning (ML) models for cosmological parameter prediction
Experiments in visualizing dark matter and baryonic matter maps
File formats:
grid_density_z0.npy → 3D NumPy array containing matter density values
params.json → Cosmological parameter metadata (Ωm, σ₈, etc.)
📊 Dataset Specifications Source Data: CAMELS Multifield Dataset
Grid Resolution: 256³ voxels (example)
Data Type: Dark matter density field
Redshift: z = 0
