First Data Release of the PHANGS-MUSE large programme

Published: 16 Jul 2021

The PHANGS-MUSE project is an ESO Large Programme (PROGRAM ID: 1100.B-0651, PI: E. Schinnerer) which (including exposures from archival programs: 094.B-0321, 094.C-0623, 095.C-0473, 097.B-0640, 098.B-0551, 099.B-0242, 0100.B-0116) maps with MUSE 19 star forming spiral galaxies. This release provides combined mosaics of their central star-forming disk obtained by combining 5 to 15 MUSE pointings for each galaxy. In addition derived maps of emission line fluxes and kinematics as well as stellar kinematics are also included as ancillary files.

By combining the wide field of view offered by MUSE with the superb spatial resolution (with PSF between 0.7 and 1.0 arcsec obtained from a combination of AO and non-AO exposures), the PHANGS-MUSE observing campaign offers a comprehensive view of the chemo-dynamical evolution of the star formation process across the different environments, addressing timescales associated with star formation, quantifying the importance of stellar feedback, studying the chemical enrichment and mixing, and connecting the local conditions with the large-scale dynamics.

Two astrometrically aligned and flux calibrated mosaic cubes are provided for each object. One at the native resolution of MUSE, and one that has been homogenized such that all pointings across any individual galaxy and across wavelengths are convolved to a matched angular resolution. Further details are provided in the data release documentation. The total data volume of 1.15 TB is available via the ESO Archive Science Portal or programmatically.
