PMAS Observing Run "Planetary Nebulae and Lyman Continuum Leaker Galaxies"

• Applicant: Professor Dr. Martin Matthias Roth
• Subject Area: Astrophysics and Astronomy
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 548805523

A PMAS observing run shall investigate two scientific objectives: (1) Flux measurement in [OIII] 5007 A for luminous galactic planetary nebulae with GAIA parallaxes as reference for the luminosity function of planetary nebulae to calibrate extragalactic distance determinations for a novel and independent technique to measure the Hubble constant, (2) study of SDSS candidate galaxies for Lyman continuum escape, analogous to "green pea" galaxies.
