The Galaxy Luminosity Function at z < 0.05: Dependence on Morphology
R. O. Marzke, L. N. da Costa, P. S. Pellegrini +2
We investigate the dependence of the local galaxy luminosity function on morphology using 5,404 galaxies from the recently enlarged Second Southern Sky Redshift Survey (SSRS2). Ove…
Compact Group Selection From Redshift Surveys
Elizabeth Barton, Margaret J. Geller, Massimo Ramella +2
For the first time, we construct a catalog of compact groups selected from a complete, magnitude-limited redshift survey. We select groups with members based on projecte…
The Power Spectrum of Galaxies in the Nearby Universe
L. N. da Costa, M. S. Vogeley, M. J. Geller +2
We compute the power spectrum of galaxy density fluctuations in a recently completed redshift survey of optically-selected galaxies in the southern hemisphere (SSRS2). The amplitud…
Limits on the Primordial Fluctuation Spectrum Void Sizes and CMBR Anisotropy
T. Piran, M. Lecar, D. S. Goldwirth +2
We suggest to use the common appearance of voids with a scale of $5000 \kms$ in the galaxy distribution to estimate the power spectrum on this scale. We use a simple model for a gr…
