The PICS Project: II. Circumnebular extinction variations and their effect on the planetary nebula luminosity function
Lucas M. Valenzuela, George H. Jacoby, Rhea-Silvia Remus +2
For decades, the theoretical understanding of planetary nebulae (PNe) has remained in tension with the observed universal bright-end cutoff of the PN luminosity function (PNLF). Th…

The PICS Project. I. The impact of metallicity and helium abundance on the bright end of the planetary nebula luminosity function
Lucas M. Valenzuela, Marcelo M. Miller Bertolami, Rhea-Silvia Remus +1
Planetary nebulae (PNe) and their luminosity function (PNLF) in galaxies have been used as a cosmic distance indicator for decades, yet a fundamental understanding is still lacking…
