Candidates for the most [] -luminous planetary nebula in the Milky Way. I. Integrated light properties of NGC 6572, NGC 6884, and M 1-71
Azlizan A. Soemitro, Martin M. Roth, Jeremy R. Walsh +3
The bright-end cutoff of the planetary nebula luminosity function (PNLF) serves as an extragalactic standard candle. However, the physical properties of planetary nebulae (PNe) at…
Extragalactic Planetary Nebulae (xPNe). Chemical evolution and assembly histories of nearby galaxies using Oxygen and Argon abundances. From the local universe to cosmic dawn
Magda Arnaboldi, Ortwin Gerhard, Martin Roth +6
How galaxies formed and evolved in the expanding Universe is the main science goal of Near-Field Cosmology research. Studies of the properties of galaxies' resolved stars open a wi…
Extragalactic Planetary Nebulae (xPNe). Determining Distances out to 100 Mpc and the Renaissance of the PN Luminosity Function Method
Magda Arnaboldi, Ortwin Gerhard, Martin Roth +9
The discrepancy of the Hubble parameter H0 as measured from the cosmic microwave background versus that found from traditional distance ladder measurements has produced considerabl…
Extragalactic planetary nebulae -- tracers of kinematics and stellar populations out to 100 Mpc
Johanna Hartke, Magda Arnaboldi, Claudia Pulsoni +11
Extragalactic planetary nebulae (xPNe) in galaxies beyond the Local Universe serve as discrete tracers for studying the element abundances and kinematics of galaxies covering a wid…
Serendipitous Discovery of a Faint Planetary Nebula in the Massive Young LMC Cluster NGC 1866
Howard E. Bond, Nate Bastian, Andrea Bellini +5
During an integral-field spectroscopic study of stars in the massive young open cluster NGC 1866 in the Large Magellanic Cloud, we serendipitously discovered a faint planetary nebu…
Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE. III. Impact of Stellar Populations in Early-Type Galaxy
Azlizan A. Soemitro, Lucas M. Valenzuela, Martin M. Roth +5
Distance measurements using the planetary nebula luminosity function (PNLF) rely on the bright-end power-law cut-off magnitude (), which is defined by a number of the [OIII]$\…
