We use the Illustris simulation to study the distributions of ellipticities and kinematic misalignments of galactic projections, as well as the intrinsic shapes and rotation of the simulated galaxies. Our results for the projections of galaxies display clear trends of an overall increase of kinematic misalignment and a slight decrease of ellipticity for fast rotators with increasing masses, while revealing no clear distinction between slow rotators of different mass. It is also found that the… 
The MASSIVE Survey XIV—Stellar Velocity Profiles and Kinematic Misalignments from 200 pc to 20 kpc in Massive Early-type Galaxies
We use high spatial resolution stellar velocity maps from the Gemini GMOS integral-field spectrograph (IFS) and wide-field velocity maps from the McDonald Mitchell IFS to study the stellar velocity

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
Recovering the intrinsic shape of early‐type galaxies
We investigate how well the intrinsic shape of early-type galaxies can be recovered when both photometric and two-dimensional stellar kinematic observations are available. We simulate these
The connection between mass, environment, and slow rotation in simulated galaxies
Recent observations from integral field spectroscopy (IFS) indicate that the fraction of galaxies that are slow rotators, FSR, depends primarily on stellar mass, with no significant dependence on
Kinematics of simulated galaxies – I. Connecting dynamical and morphological properties of early-type galaxies at different redshifts
State-of-the-art integral field surveys like ATLAS(3D), SLUGGS, CALIFA, SAMI, and MaNGA provide large data sets of kinematical observations of early-type galaxies (ETGs), yielding constraints on the
Structure and Kinematics of Early-Type Galaxies from Integral Field Spectroscopy
Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are

We use the ATLAS3D sample of 260 early-type galaxies to study the apparent kinematic misalignment angle, Ψ, defined as the angle between the photometric and kinematic major axes. We find that 71 per
SDSS-IV MaNGA : stellar angular momentum of about 2300 galaxies: unveiling the bimodality of massive galaxy properties
We measure λRe, a proxy for galaxy specific stellar angular momentum within one effective radius, and the ellipticity, e, for about 2300 galaxies of all morphological types observed with integral

A large-scale hydrodynamical cosmological simulation, Horizon-AGN , is used to investigate the alignment between the spin of galaxies and the large-scale cosmic filaments above redshift one. The

We analyse the orbital distribution of elliptical (E) and lenticular (S0) galaxies using SAURON integral-field stellar kinematics within about one effective (half-light) radius. We construct the
