Kinematics and dynamics of the haloes of supergiant galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1985
On presente des mesures de la cinematique interne des halos de 3 galaxies supergeantes dans des amas moderement riches. On trouve que les profils de la dispersion des vitesses sont plats ou croissent avec le rayon.

Dynamics of Intermediate-Mass Black Holes Wandering in the Milky Way Galaxy Using the Illustris TNG50 Simulation [PDF]

, 2022
The detection of Intermediate-Mass Black Holes (IMBHs) in dwarf galaxies is crucial to closing the gap in the wide mass distribution of black holes (∼ 3M to ∼ 5 × 1010M ). IMBHs originally located at the center of dwarfs that later collide with the Milky

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 ...

Kinematics and dynamics of the Galactic bar revealed by Gaia long-period variables [PDF]

Monthly notices of the Royal Astronomical Society
We use low-amplitude, long period variable (LA-LPV) candidates in Gaia DR3 to trace the kinematics and dynamics of the Milky Way bar. LA-LPVs, like other LPVs, are intrinsically bright and follow a tight period-luminosity relation, but unlike e.g. Mira

mg-mamposst: a code to test modifications of gravity with internal kinematics and lensing analyses of galaxy clusters [PDF]

, 2020
We present an upgraded version of \emph{MG-MAMPOSSt}, a code to constrain modified gravity models with the dynamics of galaxy cluster's members, based on the original \emph{MAMPOSSt} method, along with an application to forecasts.

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.

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 and Dynamics of the Isolated Interacting Galaxy Pair NGC 5426/27 (ARP 271) [PDF]

, 2001
We present H alpha observations of the isolated interacting galaxy pair NGC 5426/27 using the scanning Fabry-Perot interferometer PUMA. The velocity field, various kinematical parameters and rotation curve for each galaxy were derived.

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 ...
