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]$\…
The heart of NGC 5253 as seen with MUSE-NFM: nitrogen enrichment through stellar chemical feedback at parsec scales
Brigitte G. A. Pruijt, Ana Monreal-Ibero, Peter M. Weilbacher +5
NGC 5253 is a nearby (D=3.6 Mpc) Blue Compact Dwarf galaxy, notable for its three massive young super star clusters (SSCs) and nitrogen enrichment. Its similarity to extreme star-f…
Temperature-compensating package for OH line filters for astronomy: II. manufacture, assembly, and performance study
Xijie Luo, Carlos E. Rodriguez Alvarez, Aashia Rahman +7
Multi-channel aperiodic fiber Bragg grating (FBG) based hydroxyl (OH) line filters have attracted significant interest in ground-based near-infrared (NIR) astronomical observations…
A 500 pc volume-limited sample of hot subluminous stars I. Space density, scale height, and population properties
H. Dawson, S. Geier, U. Heber +25
We present the first volume-limited sample of spectroscopically confirmed hot subluminous stars out to 500 pc, defined using the accurate parallax measurements from the {\em Gaia}…
Integral Field Spectroscopy: a disruptive innovation for observations of Planetary Nebulae and the PNLF
Martin M. Roth, George Jacoby, Robin Ciardullo +3
A quarter of a century has passed since the observing technique of integral field spectroscopy (IFS) was first applied to planetary nebulae (PNe). Progress after the early experime…
Precision spectrophotometry for PNLF distances: the case of NGC 300
Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5
The Multi-Unit Spectroscopic Explorer (MUSE) has enabled a renaissance of the planetary nebula luminosity function (PNLF) as a standard candle. In the case of NGC 300, we learned t…
MUSE crowded field 3D spectroscopy in NGC 300 : IV. Planetary nebula luminosity function
Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5
We perform a deep survey of planetary nebulae (PNe) in the spiral galaxy NGC 300 to construct its planetary nebula luminosity function (PNLF). We aim to derive the distance using t…
MUSE crowded field 3D spectroscopy in NGC 300 III. Characterizing extremely faint HII regions and diffuse ionized gas
Genoveva Micheva, Martin M. Roth, Peter M. Weilbacher +7
There are known differences between the physical properties of HII and diffuse ionized gas (DIG), but most of the studied regions in the literature are relatively bright. We compil…
