We have analysed a sample of satellite and primary galaxies in the 2dF Galaxy Redshift Survey. In our study we find strong statistical evidence of the Holmberg effect (that is, a tendency for satellites to avoid regions along the line defined by the primary plane) within 500 kpc of the projected distance to the primary. This effect is present only when we restrict our analysis to objects with radial velocity relative to the primary |Δν| < 160 km s -1 , which corresponds approximately to the… Expand
Color dependence in the spatial distribution of satellite galaxies
Aims. We explore the color dependence of the radial profile of satellite galaxies around isolated parent galaxies. Methods. Samples of potential satellites selected from large galaxy redshift surveysExpand
The anisotropic distribution of satellite galaxies
We identify satellites of isolated galaxies in the Sloan Digital Sky Survey and examine their angular distribution. Using mock catalogues generated from cosmological N-body simulations, weExpand
The alignment between satellites and central galaxies: theory versus observations
Recent studies have shown that the distribution of satellite galaxies is preferentially aligned with the major axis of their central galaxy. The strength of this alignment has been found to dependExpand
Constraints on the angular distribution of satellite galaxies about spiral hosts
We present, using a novel technique, a study of the angular distribution of satellite galaxies around a sample of isolated, blue host galaxies selected from the sixth data release of the SloanExpand
The alignment between the distribution of satellites and the orientation of their central galaxy
We use galaxy groups selected from the Sloan Digital Sky Survey to examine the alignment between the orientation of the central galaxy (defined as the brightest group member) and the distribution ofExpand
Detection of the Effect of Cosmological Large-Scale Structure on the Orientation of Galaxies
Galaxies are not distributed randomly throughout space but are instead arranged in an intricate cosmic web of filaments and walls surrounding bubble-like voids. There is still no compellingExpand
The abundance of satellites depends strongly on the morphology of the host galaxy
Using the spectroscopic catalogue of the Sloan Digital Survey Data Release 10, we have explored the abundance of satellites around a sample of 254 massive (10^11 10^9 M_sun and R 0.1. The fact thatExpand
The Distribution of Satellites Around Central Galaxies in a Cosmological Hydrodynamical Simulation
Observations have shown that the spatial distribution of satellite galaxies is not random, but rather is aligned with the major axes of central galaxies (CGs). The strength of the alignment isExpand
Angular distribution of satellite galaxies from the Sloan Digital Sky Survey Data Release 4
We explore the angular distribution of two samples of satellite galaxies orbiting isolated hosts extracted from the Sloan Digital Sky Survey Data Release 4. We find a clear alignment of theExpand
The galaxy cross-correlation function as a probe of the spatial distribution of galactic satellites
The spatial distribution of satellite galaxies around host galaxies can illuminate the relationship between satellites and dark matter subhalos and aid in developing and testing galaxy formationExpand


Anisotropies in the Distribution of Satellite Galaxies
We find that satellites of isolated disk galaxies at projected radii between 300 and 500 kpc are distributed asymmetrically about the parent galaxy and aligned preferentially with the disk minorExpand
Observing the Dark Matter Density Profile of Isolated Galaxies
Using the Sloan Digital Sky Survey (SDSS), we probe the halo mass distribution by studying the velocities of satellites orbiting isolated galaxies. In a subsample that covers 2500 deg2 on the sky, weExpand
On the Holmberg asymmetry of the satellites of disk galaxies
A tidal explanation for the observation by Holmberg that the satellites of edge-on disk galaxies tend to avoid the sector within + or - 30 deg of the major axes of the disk galaxies is considered. ItExpand
Satellites of spiral galaxies
We present a survey of satellites around a homogeneous set of late-type spirals with luminosity similar to that of the Milky Way. On average, we find fewer than 1.5 satellites per primary, but weExpand
The asymmetric distribution of satellite galaxy velocities
Companion galaxies tend to have redshifts that exceed that of their associated primary. We show that the latest sample of satellite galaxies (from Zaritsky et al.) corroborates this assertion. WeExpand
Anisotropic Distribution of SDSS Satellite Galaxies: Planar (Not Polar) Alignment
The distribution of satellite galaxies relative to isolated host galaxies in the Sloan Digital Sky Survey (SDSS) is investigated. Host-satellite systems are selected using three different methods,Expand
What determines the morphological fractions in clusters of galaxies
A reexamination of Dressler's sample of nearly 6000 galaxies in 55 clusters shows that the morphology-clustercentric radius relation is more fundamental than the morphology-local density relation.Expand
Simulations of Galaxy Formation in a Λ Cold Dark Matter Universe. II. The Fine Structure of Simulated Galactic Disks
We present a detailed analysis of the disk component of a simulated galaxy formed in the ΛCDM cosmogony. At redshift z = 0, two distinct dynamical components are easily identified solely on the basisExpand
Satellite decay in flattened dark matter haloes
We carry out a set of self-consistent N-body calculations to compare the decay rates of satellite dwarf galaxies orbiting a disc galaxy embedded in a dark matter halo (DMH). We consider bothExpand
