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.

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.

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 features, motions, and perturbations can ...

Structure and dynamics of galaxies with a low surface-brightness disc - I. The stellar and ionized-gas kinematics [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 (abridged) Photometry and long-slit spectroscopy are presented for a sample of 6 galaxies with a low surface brightness stellar disc and a bulge. The stellar and ionised-gas kinematics were measured along the major and minor axis in half of the sample galaxies, whereas the other half was observed only along two diagonal axes. Spectra along two diagonal

Dark Matter in Fractional Gravity III: Dwarf Galaxies Kinematics [PDF]
Universe, 2023 Recently, we put forward a framework where the dark matter (DM) component within virialized halos is subject to a non-local interaction originated by fractional gravity (FG) effects.

The ALMA-ALPAKA survey. I. High-resolution CO and [CI] kinematics of star-forming galaxies at z= 0.5 - 3.5 [PDF]
Astronomy & Astrophysics, 2023 Spatially-resolved studies of the kinematics of galaxies provide crucial insights into their assembly and evolution, enabling to infer the properties of the dark matter halos, derive the impact of feedback on the ISM, characterize the outflow motions. To

A New Method for the Reconstruction of Strongly Lensed Galaxies with Resolved Kinematics [PDF]
Astrophysical Journal, 2022 Integral field spectroscopy of high-redshift galaxies has become a powerful tool for understanding their dynamics and evolutionary states. However, in the case of gravitationally lensed systems, it has proved difficult to model both lensing and intrinsic

Molecular gas kinematics in the nuclear region of nearby Seyfert galaxies with ALMA [PDF]
Astronomy & Astrophysics, 2021 We present the analysis of the molecular gas in the nuclear regions of NGC 4968, NGC 4845, and MCG-06-30-15, with the help of ALMA observations of the CO(2-1) emission line.

The dynamics of three nearby E0 galaxies in refracted gravity [PDF]
Astronomy & Astrophysics, 2021 We tested whether refracted gravity, a theory of modified gravity that describes the dynamics of galaxies without the aid of dark matter, can model the dynamics of the three massive elliptical galaxies, NGC 1407, NGC 4486, and NGC 5846, out to $\sim ...
