THE SAMI GALAXY SURVEY: REVISITING GALAXY CLASSIFICATION THROUGH HIGH-ORDER STELLAR KINEMATICS [PDF]

, 2016
Recent cosmological hydrodynamical simulations suggest that integral field spectroscopy can connect the high-order stellar kinematic moments h3 (∼skewness) and h4 (∼kurtosis) in galaxies to their cosmological assembly history.

IMAGES. I. Strong evolution of galaxy kinematics since z = 1 [PDF]

, 2007
Nearly half the stellar mass of present-day spiral galaxies has formed since z = 1, and galaxy kinematics is an ideal tool to identify the underlying mechanisms responsible for the galaxy mass assembly since that epoch. Here, we present the first results

Updated results on the galaxy–halo connection from satellite kinematics in SDSS [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present new results on the relationship between central galaxies and dark matter haloes inferred from observations of galaxy abundances and satellite kinematics in the Sloan Digital Sky Survey (SDSS) DR7. We employ an updated analysis framework that

Dwarf spheroidal galaxy kinematics and spiral galaxy scaling laws [PDF]

, 2011
Kinematic surveys of the dwarf spheroidal (dSph) satellites of the Milky Way are revealing tantalising hints about the structure of dark matter (DM) haloes at the low-mass end of the galaxy luminosity function.

Measuring galaxy cluster mass profiles into the low-acceleration regime with galaxy kinematics [PDF]

Astronomy & Astrophysics, 2023
We probe the dynamical mass profiles of 10 galaxy clusters from the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS) using galaxy kinematics. We numerically solve the spherical Jeans equation, and parameterize the dynamical mass profile and the galaxy

What drives galaxy quenching? A deep connection between galaxy kinematics and quenching in the local Universe [PDF]

, 2022
We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15).

The Keck Baryonic Structure Survey: using foreground/background galaxy pairs to trace the structure and kinematics of circumgalactic neutral hydrogen at z ∼ 2 [PDF]

Monthly notices of the Royal Astronomical Society, 2020
We present new measurements of the spatial distribution and kinematics of neutral hydrogen in the circumgalactic and intergalactic medium surrounding star-forming galaxies at z ∼ 2.

Distinguishing Mergers and Disks in High-redshift Observations of Galaxy Kinematics [PDF]

Astrophysical Journal, 2019
The majority of massive star-forming galaxies at z ∼ 2 have velocity gradients suggestive of rotation, in addition to large amounts of disordered motions.
