Kinematics and dynamics of the luminous infrared galaxy pair NGC 5257/58 (Arp 240) [PDF]
Astronomy & Astrophysics, 2018 Context. Encounters between galaxies modify their morphology, kinematics, and star formation history. The relation between these changes and external perturbations is not straightforward. The great number of parameters involved requires both the study of large samples and individual encounters where particular ...

Stellar dynamics and dark matter in Local Group dwarf galaxies [PDF]
, 2022 When interpreted within the standard framework of Newtonian gravity and dynamics, the kinematics of stars and gas in dwarfmgalaxies reveals that most of these systems are completely dominated by their dark matter halos.

Chemical and kinematical evolution in nearby dwarf spheroidal galaxies [PDF]
, 2006 Dwarf spheroidal (dSph) galaxies are the least massive and luminous objects known to exist. These galaxies are often considered as the fossil building blocks of massive systems predicted by some cosmological models.

Extreme kinematic misalignment in IllustrisTNG galaxies: the origin, structure, and internal dynamics of galaxies with a large-scale counterrotation [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We provide an in-deep analysis of 25 galaxies with substantial counterrotation from IllustrisTNG100 simulations in the stellar mass range 2×109−3×1010 M⊙. The counterrotation is a result of an external gas infall ≈2–8 Gyr ago.

Made-to-measure dynamical particle models of elliptical galaxies [PDF]
, 2007 NMAGIC modelling: Syer and Tremaine (1996) proposed a made-to-measure (M2M) algorithmto construct N-particle systems from observational data and used it to generate a triaxial model from density observables.

The kinematics and dynamics of the rich cluster of galaxies Abell 539
The Astronomical Journal, 1988 A sample of 289 redshifts within 10 deg of the center of the cluster A539 have been obtained in order to investigate the cluster kinematics and dynamics. Within 1 Mpc of the center, the physical parameters of A539 are found to be typical of those of rich clusters.

SDSS IV MaNGA: full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies [PDF]
, 2019 By applying spectroscopic decomposition methods to a sample of MaNGA early-type galaxies, we separate out spatially and kinematically distinct stellar populations, allowing us to explore the similarities and differences between galaxy bulges and discs ...

Kinematic and Dynamics of the Galaxy ESO 358-60
The Astrophysical JournalAbstract We investigate the velocity field derived from H I measurements of the irregular galaxy ESO 358-60 using the velocity ring model (VRM) method. This technique, which assumes a coplanar disk, allows us to reconstruct coarse-grained maps of both radial and tangential ...

Experimental Physiology, EarlyView.Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...
