Theoretical Estimates of Intrinsic Galaxy Alignment
It has recently been argued that the observed ellipticities of galaxies may be determined at least in part by the primordial tidal gravitational field in which the galaxy formed. Long-range correlations in the tidal field could thus lead to an ellipticityellipticity correlation for widely separated galaxies. We present a new model relating ellipticity to angular momentum, which can be calculate...
متن کاملIntrinsic galaxy shapes and alignments II: Modelling the intrinsic alignment contamination of weak lensing surveys
Intrinsic galaxy alignments constitute the major astrophysical systematic of forthcoming weak gravitational lensing surveys but also yield unique insights into galaxy formation and evolution. We build analytic models for the distribution of galaxy shapes based on halo properties extracted from the Millennium Simulation, differentiating between earlyand late-type galaxies as well as central gala...
متن کاملDynamic Tidal Alignment of Cluster Galaxies
We investigate the role of parametric tidal interactions between cluster galaxies and the cluster potential by considering galaxy and cluster dynamical properties and drawing an analogy between these systems and the Milky Way-dSph system. We suggest that some cluster galaxies are indeed undergoing resonant excitation and argue that this will cause a tendency for alignment of the galaxies’ long ...
متن کاملProbing the Intrinsic Shape and Alignment of Dark Matter Haloes using SDSS Galaxy Groups
We study the three-dimensional and projected shapes of galaxy groups in the Sloan Digital Sky Survey Data Release 4, and examine the alignment between the orientation of the central galaxy and the spatial distribution of satellite galaxies. The projected ellipticity of a group is measured using the moments of the discrete distribution of its member galaxies. We infer the three-dimensional and p...
متن کاملTesting Tidal-Torque Theory: II. Alignment of Inertia and Shear and the Characteristics of Proto-haloes
We investigate the cross-talk between the two key components of tidal-torque theory, the inertia (I) and shear (T ) tensors, using a cosmological N -body simulation with thousands of well-resolved haloes. We find that the principal axes of I and T are strongly aligned, even though I characterizes the proto-halo locally while T is determined by the large-scale structure. Thus, the resultant gala...
