Planetary Nebulae in Galaxy M33 with J-PLUS Photometry

A pilot study investigates the planetary nebula population in the nearby spiral galaxy M33, located approximately 840 kpc away. The dataset likely contains photometric data for 98 known planetary nebulae, extracted from the 12-band Javalambre-Photometric Local Universe Survey DR3. It was authored by G. Liberato and published on figshare in May 2026.

Use Cases

• Identifying emission-line objects based on photometric criteria developed for Milky Way halo planetary nebulae.
• Cross-matching photometric candidates with existing catalogs to distinguish planetary nebulae from contaminants like H II regions.
• Analyzing radial velocities of known planetary nebulae to identify potential halo objects.
• Developing methods for detecting extragalactic planetary nebulae in multi-band surveys like J-PLUS, S-PLUS, and J-PAS.

Strengths

• Photometry for 98 known planetary nebulae in M33.
• Data sourced from the 12-band J-PLUS DR3 survey.
• Includes analysis of radial velocities from literature.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The study recovered photometry for only a fraction of the known population, highlighting methodological challenges.
