Galaxy Spin Statistics and Spin-density Correlation
نویسندگان
چکیده
We present a theoretical study of galaxy spin correlation statistics, with detailed technical derivations. We also find an expression for the spin-density cross-correlation, and apply that to Tully catalog. The observational results appear qualitatively consistent with the theoretical predictions, yet the error bars are still large. However, we expect that currently ongoing large surveys such as the SDSS will enable us to make precision measurement of these correlation statistics in the near future. These observables are tracers of the galaxy-gravity interaction, which may provide us a deeper insight into the galaxy formation and large scale matter distribution as well.

متن کاملCosmic Shear from Galaxy Spins.
We discuss the origin of galactic angular momentum and the statistics of the present-day spin distribution. It is expected that the galaxy spin axes are correlated with the intermediate principal axis of the gravitational shear tensor. This allows one to reconstruct the shear field and thereby the full gravitational potential from the observed galaxy spin fields. We use the direction of the ang...

We present a theoretical study of void spins and their correlation properties. The concept of the spin angular momentum for an unbound void is introduced to quantify the effect of the tidal field on the distribution of matter that make up the void. Both the analytical and numerical approaches are used for our study. Analytically, we adopt the linear tidal torque model to evaluate the void spin-...

We report the first direct observational evidence for alignment of galaxy spin axes with the local tidal shear field. We measure quantitatively the strength of this directional correlation of disk galaxies from the Tully catalog with the local shear field reconstructed from PSCz galaxies. We demonstrate that the null hypothesis of random galaxy alignments relative to the shear frame can be rule...

We present a theoretical study of void spins and their correlation properties. Both the analytical and numerical approaches are used for our study. Analytically , we adopt the linear tidal torque model to evaluate the void spin-spin and spin-density correlations, assuming that a void forms in the initial region where the inertia momentum and the tidal shear tensors are maximally uncorrelated wi...
