Gas and stellar dynamics in Stephan's Quintet. Mapping the kinematics in a closely interacting compact galaxy group [PDF]

, 2021
In nearby compact galaxy groups we can study the complex processes of galaxy interactions at high resolution and obtain a window into a time in the history of the Universe when the galaxies were closely spaced and the intergalactic medium was awash with ...

The Dynamics of White Dwarfs, Black Holes and Stellar Cusps [PDF]

, 2013
This thesis contains topics related mostly to the dynamics of white dwarfs (chapter 2), the dynamics of stars around binary super massive black holes (chapters 4, 5 and 6) and dynamics in the singular isothermal sphere (chapter 7).

Morphology, Stellar Kinematics and Dynamics of Barred Galaxies [PDF]

Symposium - International Astronomical Union, 1983
A brief review is given of the morphology of barred galaxies, following Kormendy (1981, 1982). The features illustrated include bulges, bars, disks, lenses, and inner and outer rings.Most of the paper is devoted to a detailed discussion of the absorption-line velocity field of the prototypical SBO galaxy NGC 936.

Ionized and Molecular Gas Kinematics in a z=1.4 Star-forming Galaxy [PDF]

, 2020
We present deep observations of a z = 1.4 massive, star-forming galaxy (SFG) in molecular and ionized gas at comparable spatial resolution (CO 3–2, NOrthern Extended Millimeter Array (NOEMA); Hα, Large Binocular Telescope (LBT)).

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.

Kinematics of simulated galaxies – I. Connecting dynamical and morphological properties of early-type galaxies at different redshifts [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
State-of-the-art integral field surveys like $\mathrm{ATLAS^{3D}}$, SLUGGS, CALIFA, SAMI, and MaNGA provide large data sets of kinematical observations of early-type galaxies (ETGs), yielding constraints on the formation of ETGs. Using the cosmological hydrodynamical \textit{Magneticum Pathfinder} simulations, we investigate the paradigm of fast and ...

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.

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.

Neutral versus ionized gas kinematics at z ≃ 2.6: the AGN-host starburst galaxy PKS 0529-549 [PDF]

, 2018
International audienceWe present a multiwavelength study of the AGN-host starburst galaxy PKS 0529-549 at z ≃ 2.6. We use (1) new ALMA observations of the dust continuum and of the [CI] 370 μm line, tracing molecular gas, (2) SINFONI spectroscopy of the [

Kinematic and Dynamics of the Galaxy ESO 358-60

The Astrophysical Journal
Abstract 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 ...
