Kinematics of Cluster Galaxies and Their Relation to Galaxy Evolution [PDF]
The Astrophysical Journal, 2019 Abstract We study the kinematics of galaxies within massive clusters, as a probe of the physics of star formation quenching within clusters. Using N-body simulations, we argue that satellite kinematics provide information about galaxy infall that is complementary to the (instantaneous) spatial distribution of satellites and can help ...

Galaxy Zoo: kinematics of strongly and weakly barred galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We study the bar pattern speeds and corotation radii of 225 barred galaxies, using integral field unit data from MaNGA and the Tremaine–Weinberg method. Our sample, which is divided between strongly and weakly barred galaxies identified via Galaxy Zoo, is the largest that this method has been applied to. We find lower pattern

IMAGES I. Strong evolution of galaxy kinematics since z=1
, 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

Kinematics of edge-on galaxy disks
, 2002 We have obtained optical spectra and H I maps for a sample of edge-on spirals. Together with existing photometry, this data allows us to study simultaneously the 3D structure and the kinematics of galaxy disks. This is briefly illustrated for IC 2531. A synthesis of the stellar and H I kinematics for the entire sample reveals a correlation between the ...

Mapping galaxy components with kinematics : dynamical models with stellar and gaseous kinematics [PDF]
, 2021 Mapping galaxy mass distribution is an important means of understanding galaxy morphology and the nature of dark matter haloes, and therefore build up our knowledge of galaxy formation and evolution.

The SAMI Galaxy Survey: revisiting galaxy classification through high-order stellar kinematics [PDF]
, 2017 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.

Structure and kinematics of a massive galaxy at [PDF]
, 2023 Context. Observations of the rest-frame UV emission of high-redshift galaxies suggest that the early stages of galaxy formation involve disturbed structures.

Structure and kinematics of the Virgo cluster of galaxies [PDF]
Astronomy & Astrophysics, 2020 Aims. This work considers the Virgo cluster of galaxies, focusing on its structure, kinematics, and morphological landscape. Our principal aim is to estimate the virial mass of the cluster. For this purpose, we present a sample of 1537 galaxies with radial velocities VLG < 2600 km s−1 situated within a region of ΔSGL = 30° and ΔSGB = 20° around M ...

The Kinematics of z ≳ 6 Quasar Host Galaxies [PDF]
The Astrophysical Journal, 2021 Abstract We explore the kinematics of 27 z ≳ 6 quasar host galaxies observed in [C ii] 158 μm ([C ii]) emission with the Atacama Large Millimeter/submillimeter Array at a resolution of ≈025. We find that nine of the galaxies show disturbed [C ii] emission, due to either a close companion galaxy or a recent merger.
