We re-examine the evidence for a violation of large-scale statistical isotropy in the distribution of projected spin vectors of spiral galaxies. We have a sample of ∼37 000 spiral galaxies from the Sloan Digital Sky Survey, with their line of sight spin direction confidently classified by members of the public through the online project Galaxy Zoo. After establishing and correcting for a certain level of bias in our handedness results we find the winding sense of the galaxies to be consistent…

Galaxy Zoo: chiral correlation function of galaxy spins
Galaxy Zoo is the first study of nearby galaxies that contains reliable information about the spiral sense of rotation of galaxy arms for a sizeable number of galaxies. We measure the correlation
Galaxy Zoo: a correlation between the coherence of galaxy spin chirality and star formation efficiency
We report on the finding of a correlation between the past star formation activity of galaxies and the degree to which the rotation axes of neighbouring galaxies are aligned. This is obtained by
Fossil evidence for spin alignment of Sloan Digital Sky Survey galaxies in filaments
We search for and find fossil evidence that the spin axes of galaxies in cosmic web filaments relative to their host filaments are not randomly distributed. This indicates the fact that the action of
Galaxy Zoo: comparing the demographics of spiral arm number and a new method for correcting redshift bias
The majority of galaxies in the local Universe exhibit spiral structure with a variety of forms. Many galaxies possess two prominent spiral arms, some have more, while others display a many-armed

Multiple previous studies using several different probes have shown considerable evidence for the existence of cosmological-scale anisotropy and a Hubble-scale axis. One of the probes that show such
Only marginal alignment of disc galaxies
Testing theories of angular-momentum acquisition of rotationally supported disc galaxies is the key to understanding the formation of this type of galaxies. The tidal-torque theory aims to explain

Abstract Spin patterns of spiral galaxies can be broadly separated into galaxies with clockwise (Z-wise) patterns and galaxies with counterclockwise (S-wise) spin patterns. While the differences
Galaxy Zoo: Dust in Spirals
We investigate the effect of dust on spiral galaxies by measuring the inclination-dependence of optical colours for 24,276 well-resolved SDSS galaxies visually classified in Galaxy Zoo. We find clear


A catalog of spin orientation of southern galaxies
A catalog is presented for studying the distribution of spin angular momentum of disk galaxies. This catalog compiles the spiral winding sense, which can be used for identifying the sign of the
A Catalog of Morphologically Classified Galaxies from the Sloan Digital Sky Survey: North Equatorial Region
We present a catalog of morphologically classified bright galaxies in the north equatorial stripe (230 deg2) derived from the Third Data Release of the Sloan Digital Sky Survey (SDSS). Morphological
On the direction of rotation of the spirals in galaxies
The detection of trailing arms in twenty spiral galaxies, completed by the 60s, allowed one to suggest the overwhelming prevalence of this sense of rotation. Pasha and Dambis (1982) have recently
Galaxy Zoo: morphologies derived from visual inspection of galaxies from the Sloan Digital Sky Survey
In order to understand the formation and subsequent evolution of galaxies one must first distinguish between the two main morphological classes of massive systems: spirals and early-type systems.
The Sloan Digital Sky Survey: Technical summary
The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and nonluminous matter in the universe: a photometrically and
Galaxy Zoo: the dependence of morphology and colour on environment
We analyse the relationships between galaxy morphology, colour, environment and stellar mass using data for over 105 objects from Galaxy Zoo, the largest sample of visually classified morphologies
Angular momentum from tidal torques. [For galactic cluster evolution model]
The origin of the angular momentum of bound objects in large N-body simulations is studied using three sets of models. One model with white-noise initial conditions is analyzed as well as two in
Multipole vectors - A New representation of the CMB sky and evidence for statistical anisotropy or non-Gaussianity at 2 <= l <= 8
We propose a novel representation of cosmic microwave anisotropy maps, where each multipole order $\mathcal{l}$ is represented by $\mathcal{l}$ unit vectors pointing in directions on the sky and an
HEALPix: A Framework for High-Resolution Discretization and Fast Analysis of Data Distributed on the Sphere
This paper considers the requirements and implementation constraints on a framework that simultaneously enables an efficient discretization with associated hierarchical indexation and fast analysis/synthesis of functions defined on the sphere and demonstrates how these are explicitly satisfied by HEALPix.
