Dataset description
Catalog of planetary nebulae from the MUSE (Multi Unit Spectroscopic Explorer) survey on ESO's Very Large Telescope, with positions and [OIII] 5007 magnitudes across multiple host galaxies. From Jacoby et al. (2024, ApJS, 271, 40).
Planetary nebulae (PNe) are glowing shells of ionized gas expelled by intermediate-mass stars (1-8 solar masses) at the end of their lives. They are important distance indicators and tracers of stellar populations and chemical enrichment. The [OIII] 5007 Angstrom line is the single brightest emission feature and serves as the standard detection and distance measurement tool through the planetary nebula luminosity function (PNLF), one of the most reliable secondary distance indicators in extragalactic astronomy.
The MUSE integral-field spectrograph provides simultaneous imaging and spectroscopy over a 1x1 arcminute field of view with 0.2-arcsecond spatial sampling, enabling detection of PNe that would be missed by traditional narrow-band imaging surveys. MUSE's spectral coverage from 4700 to 9300 Angstroms captures not only [OIII] and H-alpha but also diagnostic lines that constrain nebular excitation, chemical abundances, and central star temperature.
