Mission Overview
Physics at High Angular resolution in Nearby GalaxieS (PHANGS)
The PHANGS program has built an integrated dataset for multi-phase, multi-scale studies of star formation across nearby spiral galaxies. At its foundation is a series of large, coordinated surveys with Hubble, JWST, ALMA, and VLT/MUSE, designed to connect the processes that drive star formation on the molecular cloud and star cluster scale to the physical conditions of their local galactic environments.
Hubble and JWST imaging from 0.2 to 21 microns for 19 galaxies with ALMA CO(2-1) mapping and VLT/MUSE optical IFU spectroscopy has been obtained through three programs:
-
HST Treasury (2019-21 PI: JC Lee)
-
JWST Treasury (2022-24 PI: JC Lee)
-
HST H-alpha Treasury (2023-24 PI: R Chandar)
Hubble and JWST imaging for an additional 55 galaxies with PHANGS ALMA CO observations are being obtained through the following programs:
-
HST Treasury (2019-21 PI: JC Lee)
-
HST Treasury (2023- PI: D Thilker)
-
JWST Treasury (2023- PI: A Leroy)
-
HST H-alpha (2024- PI: F Belfiore)

PHANGS Datasets and Multiscale Stellar Associations
Author: Kirsten Larson Using the galaxy NGC 1566 as an example, this notebook shows how to download the PHANGS-HST and JWST data products. Next, the notebook shows how to download the public Multiscale Stellar associations and MUSE HII region catalogs for comparison. -
PHANGS-HST Star Cluster Catalogs
Author: Daniel Maschmann This notebook shows how to access PHANGS-CAT data and visualize star clusters and compact associations in nearby galaxies. -
Neloura Visualization Tool
Author: Hamid Hassani Tool to access and visualize a large number of datasets, including several PHANGS related products.

Empirical SED Templates for Star Clusters using HST and JWST
Author: Brad Whitmore
Ancillary data from Whitmore et al. 2025. Please view the README file for column descriptions/further information. Two different types of files each with two different formats (.csv, .fits), one of which is the "mean-value" SED template as discussed in section 3.1 of Whitmore et al. 2025. There is also a "lower-limit" version available, which mainly varies in the range 4 - 5 Myr.
