Physics at High Angular resolution in Nearby GalaxieS - HST ("PHANGS-HST")

The PHANGS program is building a panchromatic dataset to enable the multi-phase, multi-scale study of star formation across nearby spiral galaxies.  PHANGS combines Atacama Large Millimeter/submillimeter Array (ALMA) CO(2-1) mapping, Very Large Telescope/Multi Unit Spectroscopic Explorer (VLT/MUSE) optical spectroscopy, Hubble Space Telescope (HST) UV-optical imaging, and James Webb Space Telescope (JWST) infrared imaging among other supporting datasets.   PHANGS is using these data to study the star formation cycle and various phases of the interstellar medium.

The PHANGS-HST Treasury survey obtained five band NUV-U-B-V-I imaging of the disks of 38 spiral galaxies (plus 1 companion dwarf galaxy) at distances of 4-23 Mpc, and parallel V and I band imaging of their halos.  Here the team provides image products for the primary observations, as well as convolutional neural network models for image classification of star clusters and compact stellar associations.
