Kinematic Distances of Galaxies in the Local Volume
AstrophysicsWe consider the kinematic distances to nearby galaxies obtained by the Numerical Action Method (NAM) based on the Cosmic-flow-3 survey data. NAM distances are compared with 418 high-precision distances measured by the Tip of the Red Giant Branch (TRGB) method using the Hubble Space Telescope.

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

Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

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.

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.

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.

Kinematics of gas in a triaxial galaxy
The Astrophysical Journal, 1989 The morphology and kinematics of cold gas in a triaxial Staeckel potential are discussed. The properties of the gas disks and rings and their projections are examined. How observations of a ring or disk can be used to constrain the orientation of the galaxy with respect to the observer and how the intrinsic shape can be determined are analyzed, and it ...
