Challenge
Do spiral galaxies and elliptical (smooth) galaxies live in different parts of the sky brightness / redshift space? Pick two morphological classes and compare how their properties differ.
- Where to start
- Load the advanced catalogue (Parquet) reading only the columns you need — the deep-learning vote fractions for smooth vs. featured/spiral, plus any magnitude or redshift column. Filter to galaxies with confident classifications.
- What to share
- One or two clear plots (e.g. distributions or a 2D density) showing the difference, and a short paragraph on what it suggests. Share it in the forum.
