We develop a method to measure the probability, P (N ;M), of finding N galaxies in a dark-matter halo of mass M from the theoretically determined clustering properties of dark-matter halos and the observationally measured clustering properties of galaxies. Knowledge of this function and the distribution of the dark matter completely specifies all clustering properties of galaxies on scales larg...

We present a mark correlation analysis of the galaxies in the Sloan Digital Sky Survey using weights provided by MOPED. The large size of the sample permits statistically significant statements about how galaxies with different metallicities and star formation histories are spatially correlated. Massive objects formed a larger fraction of their stars at higher redshifts and over shorter timesca...

We present the rotation curves of 967 southern spiral galaxies, obtained by deprojecting and folding the raw Hα data originally published by Mathewson, Ford & Buchhorn (1992). For 900 objects, we also present, in figures and tables, the rotation curves smoothed on scales corresponding to 5% 20% of the optical size: of these, 80 meet objective excellence criteria and are suitable for individual ...

We present evidence for the existence of an old stellar halo in the dwarf irregular galaxy WLM, an isolated member of the Local Group. The halo consists of population-II stars, with low metallicities and age ≥ 10yr. The finding of a halo in a dwarf irregular galaxy argues for a generic mode of galaxy formation that requires a halo in the presence of a disk, regardless of galaxy size. This impli...

New and archival HST images of the globular cluster systems of 17 relatively nearby galaxies and 6 more distant galaxies have been used to establish the characteristics of GC subpopulations over a range of host galaxy morphological type from E5 to Sa. GC color/metallicity, size and luminosity distributions have been examined in the nearby galaxies and color distributions have been determined fo...

We estimate the mass function of void galaxies in the second public data release of the Sloan Digital Sky Survey from a sample of 1000 galaxies with local density contrasts of v < 0:6. The galaxy sample is split into ellipticals and spirals using a color-Sérsic index criterion. We estimate the virial masses of ellipticals using the measured spectral line widths along with the observed size. Pro...

Observations of six luminous blue compact galaxies (BCGs) and two star forming companion galaxies were carried out with the CIGALE scanning Fabry-Perot interferometer attached to the ESO 3.6m telescope on La Silla. The observations were made in the Hα emission line which is prominent in BCGs. A velocity sampling of 5 km/s and a pixel size of 0.9 arcseconds were used. In this paper we present th...

We estimate the Mass Function of void galaxies in the second public data release of the Sloan Digital Sky Survey from a sample of 1000 galaxies with local density contrasts of δv < −0.6. The galaxy sample is split into ellipticals and spirals using a color-Sérsic index criterion. We estimate the virial masses of ellipticals using the measured spectral line-widths along with the observed size. P...
