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…
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 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 Critical Role of Dust On The [O III] Planetary Nebula Luminosity Function's Bright-End Cutoff
George H. Jacoby, Robin Ciardullo
We examine the relationship between circumnebular extinction and core mass for sets of [O III]-bright planetary nebulae (PNe) in the Large Magellanic Cloud and M31. We confirm that…
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…
Masses of the Planetary-Nebula Central Stars in the Galactic Globular-Cluster System from HST Imaging and Spectroscopy
George H. Jacoby, Orsola De Marco, James Davies +4
The globular cluster (GC) system of our Galaxy contains four planetary nebulae (PNe): K 648 (or Ps 1) in M15, IRAS 18333-2357 in M22, JaFu 1 in Pal 6, and JaFu 2 in NGC 6441. Becau…
Post-common envelope PN, fundamental or irrelevant?
Orsola De Marco, T. Reichardt, R. Iaconi +6
One in 5 planetary nebulae are ejected from common envelope binary interactions but Kepler Space Telescope results are already showing this proportion to be larger. Their propertie…
Planetary nebulae : getting closer to an unbiased binary fraction
D. Douchin, O. De Marco, G. H. Jacoby +5
Why 80% of planetary nebulae are not spherical is not yet understood. The Binary Hypothesis states that a companion to the progenitor of the central star of a planetary nebula is r…
Searching for binary central stars of planetary nebulae with Kepler
D. Douchin, G. H. Jacoby, O. De Marco +2
The Kepler Observatory offers unprecedented photometric precision (<1 mmag) and cadence for monitoring the central stars of planetary nebulae, allowing the detection of tiny period…
The Resolved Stellar Populations of a Dwarf Spheroidal Galaxy in the Virgo Cluster
Patrick R. Durrell, Benjamin F. Williams, Robin Ciardullo +11
We report on the discovery of a faint (M_V ~ -10.6 +/- 0.2) dwarf spheroidal galaxy on deep F606W and F814W Hubble Space Telescope images of a Virgo intracluster field. The galaxy…
Kinematics of Planetary Nebulae in M51's Tidal Debris
Patrick R. Durrell, J. Christopher Mihos, John J. Feldmeier +2
We report the results of a radial velocity survey of planetary nebulae (PNe) located in the tidal features of the well-known interacting system NGC 5194/95 (M51). We find clear kin…
The Type Ia Supernova 1998bu in M96 and the Hubble Constant
S. Jha, P. Garnavich, R. Kirshner +39
We present optical and near-infrared photometry and spectroscopy of the type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measure…
