GalMorph
GalMorph is a Python package for classifying simulated galaxies into elliptical, spiral, or irregular based on their morphology probability in the TNG simulation (TNG Project).
This tool is designed to work with .pkl files containing specific probability columns and enables basic classification, filtering, and visualization of galaxy morphologies.
Expected Data Format
The input should be a Pickle file (.pkl) that can be loaded as a Pandas DataFrame, containing the following columns:
Required Columns
| Column Name | Description | Type |
|---|---|---|
Snapshot |
Simulation snapshot number | int |
SubhaloID |
Unique identifier for the galaxy/subhalo | int or str |
P_irr |
Probability the galaxy is irregular | float (0–1) |
P_disk |
Probability the galaxy is a disk | float (0–1) |
P_spheroid |
Probability the galaxy is a spheroid | float (0–1) |
Notes:
- Each probability should be a float between
0and1.
Installation
git clone https://github.com/ImPriyatam/galmorph.git
