- 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 (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 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 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.

- Description:
- We report on observations of four early-type galaxies performed with the Rutgers Fabry-Perot in order to search for planetary nebulae (PNe) in these systems. The aim is to use the PNe as kinematic tracers of the galaxy potential. We describe our data reduction and analysis procedure and show that the proper calibration of our detection statistic is crucial in getting down to our limiting magnitude of m_5007_=26.1. In the case of the two Leo galaxies, we find moderately sized samples: 54 PNe in NGC 3379 and 50 PNe in NGC 3384; NGC 4636 (two PNe) and NGC 1549 (six PNe) are included for completeness. We present our samples in tabular form, as well as the spectrum for each PN.

- Description:
- We present the result of a planetary nebula (PN) survey of the nearby giant elliptical galaxy NGC 5128 performed with CCD cameras at the prime focus of the CTIO 4m in telescope. By comparing CCD images centered on the characteristic emission line [O III] {lambda}5007{AA} and on the adjacent continuum, we identify a total of 785 PNs in areas extending 20kpc along the photometric major axis and covering the whole galaxy to 10kpc. From these data, we form a complete sample of 224 PN's extending to a dereddened limiting magnitude of m_5007_=24.8, which extends 1.5mag down the PN luminosity function (PNLF). Adopting a foreground extinction of E(B-V)=0.1, we derive a distance to the galaxy of 3.5+/-0.2Mpc, in excellent agreement with the surface brightness fluctuation method. No population effect on the bright cutoff of PNLF is observed in the isophotal radius range of 2-16kpc, but the luminosity specific PN density ({alpha}_2.5_) seems to increase with radius inside of 7kpc, in agreement with the {alpha}_2.5_-color relation observed for other galaxies.

- Publisher:

- Description:
- We present the PMAS/PPak Integral-field Supernova hosts COmpilation (PISCO), which comprises integral field spectroscopy (IFS) of 232 supernova (SN) host galaxies that hosted 272 SNe, observed over several semesters with the 3.5m telescope at the Calar Alto Observatory (CAHA). PISCO is the largest collection of SN host galaxies observed with wide-field IFS, totaling 466347 individual spectra covering a typical spatial resolution of ~380pc. Focused studies regarding specific SN Ia-related topics will be published elsewhere; this paper aims to present the properties of the SN environments, using stellar population (SP) synthesis, and the gas-phase interstellar medium, providing additional results separating stripped-envelope SNe into their subtypes. With 11270 HII regions detected in all galaxies, we present for the first time a statistical analysis of HII regions, which puts HII regions that have hosted SNe in context with all other star-forming clumps within their galaxies. SNe Ic are associated with environments that are more metal-rich and have higher EW(H{alpha}) and higher star formation rate within their host galaxies than the mean of all HII regions detected within each host. This in contrast to SNe IIb, which occur in environments that are very different compared to other core-collapse SNe types. We find two clear components of young and old SPs at SNe IIn locations. We find that SNe II fast decliners tend to explode at locations where the {Sigma}SFR is more intense. Finally, we outline how a future dedicated IFS survey of galaxies in parallel to an untargeted SN search would overcome the biases in current environmental studies.
