Abstract:
We report the results of a photometric and spectroscopic survey for
planetary nebulae (PNs) over the entire body of the Local Group spiral
galaxy M33. We use our sample of 152 PNs to show that the bright end
of the galaxy's [OIII]λ5007 planetary nebula luminosity
function (PNLF) has the same sharp cutoff seen in other galaxies.
Description:
M33's PN candidates were identified on Kitt Peak 4m telescope MOSAIC
CCD images taken as part of the NOAO Local Group Galaxies survey
program (Massey et al., 2002, BAAS, 34, 1272). To place the Massey et
al. (2002, BAAS, 34, 1272) survey frames on a standard system,
additional exposures in [OIII]λ5007(900s) and Hα(600s)
were taken with the same telescope/instrument setup on the UT nights
of 2001 Dec. 22 and 24.
