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.

Measuring dynamical masses from gas kinematics in simulated high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Advances in instrumentation have recently extended detailed measurements of gas kinematics to large samples of high-redshift galaxies. Relative to most nearby, thin disc galaxies, in which gas rotation accurately traces the gravitational potential, the interstellar medium (ISM) of $z$ ≳ 1 galaxies is typically more dynamic and ...

High-redshift quasars and their host galaxies – I. Kinematical and dynamical properties and their tracers [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT Observations of high-redshift quasars provide information on the massive black holes (MBHs) powering them and the galaxies hosting them. Current observations of z ≳ 6 hosts, at sub-millimetre wavelengths, trace the properties of cold gas, and these are used to compare with the correlations between MBHs and galaxies ...

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.

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 ...

Astronomy & Astrophysics, 2023 Strong gravitational lensing is a powerful tool to provide constraints on galaxy mass distributions and cosmological parameters, such as the Hubble constant, H0. Nevertheless, inference of such parameters from images of lensing systems is not trivial as parameter degeneracies can limit the precision in the measured lens mass and cosmological results ...

Stäackel-type Dynamic Model of the Galaxy Based on Maser Kinematic Data
Open Astronomy, 2016 Abstract A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane. The potential is then generalized to three dimensions assuming the existence of a third quadratic integral of motion. The resulting Galactic model
