- Description:
- We report the results of an [OIII] {lambda}5007 survey for PNe in five galaxies that were hosts of well-observed SNe Ia: NGC 524, NGC 1316, NGC 1380, NGC 1448, and NGC 4526. The goals of this survey are to better quantify the zero point of the maximum magnitude-decline rate relation for SNe Ia and to validate the insensitivity of Type Ia luminosity to parent stellar population using the host galaxy Hubble type as a surrogate. We detected a total of 45 PN candidates in NGC 1316, 44 candidates in NGC 1380, and 94 candidates in NGC 4526.

- Description:
- We present the results of a planetary nebula survey of M31's bulge performed with the Kitt Peak No. 1, 0.9m telescope and on-band off-band {lambda}5007 filters. We detected a total of 429 planetary nebulae (PNs), of which 104 are members of a statistically complete and homogeneous sample covering the top 2.5mag of the planetary nebula luminosity function (PNLF).

- Description:
- We present the results of a survey for planetary nebulae in the nearby Sb galaxy M81 (NGC 3031). Using the Kitt Peak 4m telescope and a TI CCD, we identify 185 planetary nebula candidates. Photometry of the nebulae extends nearly 2.5mag below the brightest candidate, although the sample is statistically homogeneous and complete for only 88 nebulae representing the top 1.2mag of the luminosity function.

- Description:
- We present the results of a planetary nebula survey of galaxies in the Leo I group performed with the Kitt Peak and Cerro Tololo 4m telescopes and on-band off-band {lambda}5007 interference filters. In all, we detected 249 PN candidates populating the top 1.5mag of the planetary nebula luminosity function (PNLF), including 93 in the E0 galaxy NGC 3379, 54 in the E6 galaxy NGC 3377, and 102 in the S0 spiral NGC 3384.

- Description:
- We present the results of a planetary nebula (PN) survey of three galaxies in the Fornax Cluster performed with the Cerro Tololo 4m telescope and on-band off-band [O III] {lambda}5007 interference filters. In all, we detected 224 PN candidates : 105 in the peculiar SO/Sa galaxy NGC 1316 (Fornax A), 47 in the E2 galaxy NGC 1404, and 72 in the central cD of the cluster NGC 1399. Using statistically complete samples of planetaries and the procedures described in previous papers in the series, we derive distances to these galaxies from the planetary nebula luminosity function (PNLF).

- Description:
- We identify and measure the [O III] {lambda}5007 fluxes of 486 planetary nebula candidates in six early-type galaxies (NGC 4374, 4382, 4406, 4472, 4486, and 4649) in the core of the Virgo Cluster. Following the procedures and calibrations outlined in previous papers in this series, we compare the observed planetary nebula luminosity functions to an empirical model based on the planetary nebulae in M31 and derive distances to the galaxies of 15.7, 14.4, 15.7, 13.9, 14.5, and 14.2Mpc.

- Description:
- We have measured the [O III] {lambda}5007 fluxes of the brightest planetaries in the LMC (102 objects) and SMC (31 objects) using narrow-band imaging at the CTIO 0.9m telescope. Our fluxes agree to -5% with photoelectric measurements available in the literature (31 objects); agreement is much worse for objects with only spectrophotometric observations. Using the fluxes for the complete sample of bright LMC planetaries, we derive a distance using the planetary nebula luminosity function (PNLF).

- Description:
- We present the results of an [O III] {lambda}5007 survey for planetary nebulae in the NGC 1023 Group. In all, we detected 143 planetary nebula candidates: 110 in the SB0 galaxy NGC 1023 and 33 in the halo of the edge-on Sb spiral NGC 891. Using a statistically complete and homogeneous sample of planetary nebulae and the procedures described in previous papers in the series, we derive distances to these galaxies using the planetary nebula luminosity function (PNLF). After correcting for foreground extinction by using the estimated reddening values of Burstein and Heiles, we find the distance moduli for NGC 1023 and NGC 891 are 29.97+/-0.14 and 29.97+/-.16, respectively. The similarity of these distances demonstrates the insensitivity of the PNLF to galaxy Hubble types and population age, and again confirms it as one of the best extragalactic standard candles.

- Description:
- Planetary Nebula distance scales often suffer for model dependent solutions. Model independent trigonometric parallaxes have been rare. Space based trigonometric parallaxes are now available for a larger sample using the second data release of Gaia. We aim to derive a high quality approach for selection criteria of trigonometric parallaxes for planetary nebulae and discuss possible caveats and restrictions in the use of this data release. A few hundred sources from previous distance scale surveys were manually cross identified with data from the second Gaia data release (DR2) as coordinate based matching does not work reliable. The data are compared with the results of previous distance scales and to the results of a recent similar study, which was using the first data release Gaia DR1. While the few available previous ground based and HST trigonometric parallaxes match perfectly to the new data sets, older statistical distance scales, reaching larger distances, do show small systematic differences. Restricting to those central stars, were photometric colors of Gaia show a negligible contamination by the surrounding nebula, the difference is negligible for radio flux based statistical distances, while those derived from H-alpha surface brightness still show minor differences. The DR2 study significantly improves the previous recalibration of the statistical distance scales using DR1/TGAS.

- Description:
- Planetary nebulae (PNe) are an important tool for studying the dynamics and chemical evolution of galaxies in the Local Universe, given their characteristic bright emission line spectra. The Andromeda Galaxy (M31) provides a unique laboratory for studying PNe in the circumnuclear region, thanks to its proximity and almost uniformly low line-of-sight extinction that ensures observations with high resolution and sensitivity. Using the WIYN/Hydra multi-fiber spectrograph, we have obtained optical (4119-6882{AA}) spectra of 77 PN candidates selected from Hubble Space Telescope narrow-band imaging, which are located within the central ~500 pc region of M31. Among these candidates, 49 (64%) are spectroscopically observed for the first time. The spectra of 300 previously known PNe and HII regions, which primarily reside in the disk, are also taken for comparison. All 77 circumnuclear PN candidates exhibit prominent emission lines, including [OIII] {lambda}5007, [NII] {lambda}6583, H{alpha} and H{beta}, strongly suggesting that they are genuine PNe. We measured the line fluxes, radial velocities and line widths for all objects, and found that the radial velocities of the circumnuclear PNe generally trace rotation of the inner bulge. We also estimated a dynamical mass of ~6.4+/-0.5x10^9^M_{sun}_ enclosed within an effective galactocentric radius of 340 pc, which is compatible with the previously estimated total stellar mass in this region.
