Abstract Many recent integral field spectroscopy (IFS) survey teams have used stellar kinematic maps combined with imaging to statistically infer the underlying distributions of galaxy intrinsic shapes. With now several IFS samples at our disposal, the method, which was originally proposed by M. Franx and collaborators in 1991, is gaining in popularity, having been so far applied to ATLAS3D, SAMI, MANGA and MASSIVE. We present results showing that a commonly assumed relationship between…

Prospects for recovering galaxy intrinsic shapes from projected quantities
The distribution of three dimensional intrinsic galaxy shapes has been a longstanding open question. The difficulty stems from projection effects meaning one must rely on statistical methods applied
The SAMI Galaxy Survey: the intrinsic shape of kinematically selected galaxies
Using the stellar kinematic maps and ancillary imaging data from the Sydney AAO Multi Integral field (SAMI) Galaxy Survey, the intrinsic shape of kinematically selected samples of galaxies is
The ATLAS 3D project - XXIV. The intrinsic shape distribution of early-type galaxies
We use the ATLAS^(3D) sample to perform a study of the intrinsic shapes of early-type galaxies, taking advantage of the available combined photometric and kinematic data. Based on our ellipticity

Due to longer dynamical time-scales, the outskirts of early-type galaxies retain the footprint of their formation and assembly. Under the popular two-phase galaxy formation scenario, an initial in
The intrinsic shape of galaxies in SDSS/Galaxy Zoo
By modelling the axis ratio distribution of SDSS DR8 galaxies we find the intrinsic 3D shapes of spirals and ellipticals. We use morphological information from the Galaxy Zoo project and assume a
The ordered nature of elliptical galaxies - Implications for their intrinsic angular momenta and shapes
The observations of rotation along the major and minor axes of 38 elliptical galaxies are analyzed to determine their intrinsic structure. Rotation along the minor axis occurs (i) as a result of

By inverting the distributions of galaxies' apparent ellipticities and misalignment angles (measured around the projected half-light radius $R_{\rm e}$) between their photometric and kinematic axes,
Introducing the Illustris Project: the evolution of galaxy populations across cosmic time
We present an overview of galaxy evolution across cosmic time in the Illustris Simulation. Illustris is an N-body/hydrodynamical simulation that evolves 2*1820^3 resolution elements in a (106.5Mpc)^3
Specific angular momentum of disc merger remnants and the λR‐parameter
We use two-dimensional kinematic maps of simulated binary disc mergers to investigate the λ R -parameter, which is a luminosity-weighted measure of projected angular momentum per unit mass. This
Triaxial galaxy models with thin tube orbits
It is shown how to construct self-consistent distribution functions for triaxial galaxy models with Stackel potentials. The Stackel potentials cause the dynamics to be simple, with all the stellar
