GSWLC-2 Galaxy Properties

Part of the Astronomy Datasets collection on Hugging Face.

659,229 galaxies with physical properties derived from UV-to-infrared spectral energy distribution (SED) fitting. GSWLC-2 (GALEX-SDSS-WISE Legacy Catalog 2) combines ultraviolet photometry from GALEX, optical photometry from SDSS, and mid-infrared photometry from WISE to estimate stellar masses, star formation rates, and dust attenuation for galaxies at redshifts 0.01 < z < 0.30.

Dataset description

The GSWLC is the definitive catalog for physical properties of low-redshift galaxies, covering ~90% of the SDSS spectroscopic footprint. Version 2 (Salim et al. 2018) incorporates WISE mid-IR photometry to better constrain dust-obscured star formation. The "X" variant (GSWLC-X2) is the master catalog that selects the deepest available UV observation for each galaxy from the A (shallow), M (medium), and D (deep) sub-catalogs.

Physical properties are derived using the CIGALE SED fitting code with Bayesian estimation of stellar mass, star formation rate, and dust attenuation.

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/gswlc-galaxy-properties", split="train")
df = ds.to_pandas()

# Star-forming galaxies
sf = df[df["is_star_forming"]]

# Massive quiescent galaxies
massive_quiescent = df[(df["log_mstar"] > 11) & (~df["is_star_forming"])]

# Star formation main sequence
import matplotlib.pyplot as plt
valid = df[df["log_sfr_sed"].notna() & df["log_mstar"].notna()]
plt.hexbin(valid["log_mstar"], valid["log_sfr_sed"], gridsize=100, mincnt=1)
plt.xlabel("log M* (Msun)")
plt.ylabel("log SFR (Msun/yr)")
plt.title("Star Formation Main Sequence")

# Dusty galaxies (high FUV attenuation)
dusty = df[df["a_fuv"] > 3.0]

# Cross-match with SDSS using objid
