Abstract:
We study the optical properties of a large sample of galaxies in
low-density regions of the nearby universe. We make a 5 h-1 Mpc
smoothed map of the galaxy density throughout the Center for
Astrophysics Redshift Survey (CfA2) to identify galaxies within three
prominent nearby "voids" with diameter ≥ 30 h-1 Mpc. We augment
the CfA2 void galaxy sample with fainter galaxies found in the same
regions from the more recent and deeper Century and Redshift surveys.
We obtain B and R CCD images and high signal-to-noise long-slit
spectra for the resulting sample of 149 void galaxies, as well as for
an additional 131 galaxies on the periphery of these voids. Here we
describe the photometry for the sample, including B isophotal
magnitudes and B-R colors.
