Abstract:
Extragalactic planetary nebulae (PNe) offer a way to determine the
distance to their host galaxies thanks to the nearly universal shape
of the luminosity function (PNLF). Accurate PNe distance measurements
rely on obtaining well- sampled PNLFs and the number of observed PNe
scales with the encompassed stellar mass. This means either disposing
of wide-field observations or on focusing on the bright central
regions of galaxies. In this work we take this second approach and
conduct a census of the PNe population in the central regions of
galaxies in the Fornax cluster, using VLT/MUSE data for the early-
type galaxies observed over the course of the Fornax3D survey. Using
such integral-field spectroscopic observations to carefully separate
the nebular emission from the stellar continuum, we isolate
[OIII] 5007Å sources of interest, filter out unresolved
impostor sources or kinematic outliers, and present a catalogue of
1350 unique PNe sources across 21 early- type galaxies, which includes
their positions, [OIII 5007Å line magnitudes and
line-of-sight velocities. Using the PNe catalogued within each galaxy,
we present independently-derived distance estimates based on the fit
to the entire observed PNLF observed while carefully accounting for
the PNe detection incompleteness. With these individual measurements
we arrive at an average distance to the Fornax cluster itself of
19.86±0.32Mpc (µPNLF=31.49±0.04mag). Our PNLF distance
measurements agree well with previous distances based on surface
brightness fluctuations, finding no significant systematic offsets
between the two methods as otherwise reported in previous studies.
Description:
We present a catalogue of 1350 unique PNe sources across 21 different
galaxies. The catalogue includes the PNe positions, their [OIII]
5007Å flux and LOSV, with the PNe population of each galaxy.
