The Vertical Structure and Kinematics of the Galaxy [PDF]
Symposium - International Astronomical Union, 1994 A sample including 2370 stars with (U, V) velocities has been analyzed up to z = 2.5 kpc. It is shown that the observed vertical gradient in the velocity distribution can be explained by the sum of 3 discrete populations with constant kinematics. The observations are well fitted by

Closing the Gap between Observed Low-mass Galaxy H i Kinematics and Cold Dark Matter Predictions
The Astrophysical JournalTesting the standard cosmological model (ΛCDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models by linking observational properties of galaxies at small scales (low mass ...

Identifying substructure associations in the Milky Way halo using chemo-kinematic tagging
Astronomy & AstrophysicsContext. The Milky Way halo has been built-up over cosmic time through the accretion and dissolution of star clusters and dwarf galaxies as well as through their complex interactions with the Galactic disc.

Kinematic modelling of disk galaxies [PDF]
Astronomy & Astrophysics, 2007 This is the second of a series of papers in which the kinematics of disk galaxies is studied by analysing spectroscopic data. Making use of the methods presented in Paper I, this work focuses on the large-scale distribution of disk and Dark Matter halo material by analysing the structure of warped galaxies.

Exploration of Halo Substructures in Integrals-of-motion Space with Gaia Data Release 3
The Astrophysical JournalUsing kinematic data from the Gaia Data Release 3 catalog, along with metallicity estimates robustly derived from Gaia BP/RP spectra, we have explored the Galactic stellar halo in search of both known and potentially new substructures.

Kinematics of the open cluster system in the Galaxy
, 2006 Absolute proper motions and radial velocities of 202 open clusters in the solar neighborhood, which can be used as tracers of the Galactic disk, are used to investigate the kinematics of the Galaxy in the solar vicinity, including the mean heliocentric ...

Connecting galaxy disk and extended halo gas kinematics
, 2008 We have explored the galaxy disk/extended halo gas kinematic relationship using rotation curves (Keck/ESI) of ten intermediate redshift galaxies which were selected by Mg II halo gas absorption observed in quasar spectra.

Galaxy-Dark Matter Connection : Insights from Satellite Kinematics
, 2009 A thorough knowledge of the connection between the mass of dark matter haloes and the properties of their central galaxies is crucial to understand the physics of galaxy formation. The kinematics of satellite galaxies is an excellent technique to measure
