Abstract:
We report the results of an [O III]λ5007 survey for planetary
nebulae (PNs) in three spiral galaxies: M101 (NGC 5457), M51
(NGC 5194/5l95), and M96 (NGC 3368). By comparing on-band/off-band
[O III]λ5007 images with images taken in Hα and broadband
R. we identify 65, 64, and 74 PN candidates in each galaxy,
respectively. From these data, an adopted M31 distance of 770kpc, and
the empirical planetary nebula luminosity function (PNLF), we derive
distances to M101, M51, and M96 of 7.7±0.5, 8.4±0.6, and
9.6±0.6Mpc. These observations demonstrate that the PNLF technique
can be successfully applied to late-type galaxies and can provide an
important overlap between the Population I and Population II distance
scales. We also discuss some special problems associated with using
the PNLF in spiral galaxies, including the effects of dust and the
possible presence of [O III] bright supernova remnants.
