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 ...

The SAMI Galaxy Survey: Kinematics of Stars and Gas in Brightest Group Galaxies—The Role of Group Dynamics [PDF]
The Astrophysical Journal, 2021 Abstract We study the stellar and gas kinematics of the brightest group galaxies (BGGs) in dynamically relaxed and unrelaxed galaxy groups for a sample of 154 galaxies in the SAMI galaxy survey. We characterize the dynamical state of the groups using the luminosity gap between the two most luminous galaxies and the BGG offset from the ...

Evaluating galaxy dynamical masses from kinematics and jeans equilibrium in simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We provide prescriptions to evaluate the dynamical mass (Mdyn) of galaxies from kinematic measurements of stars or gas using analytic considerations and the VELA suite of cosmological zoom-in simulations at z = 1–5. We find that Jeans or hydrostatic equilibrium is approximately valid for galaxies of stellar masses above M⋆ ∼ 109.

Kinematical and Dynamical Modeling of Elliptical Galaxies [PDF]
EAS Publications Series, 2006 Elements of kinematical and dynamical modeling of elliptical galaxies (Es) are presented. In projection, NFW models resemble Sersic models, but with a very narrow range of shapes (m=3+/-1). The total density profile of Es cannot be NFW-like because the predicted local M/L and aperture velocity dispersion within an effective radius (Re) are much lower ...

Photometry, Kinematics and Dynamics of the Barred Galaxy NGC 5383 [PDF]
Symposium - International Astronomical Union, 1983 NGC 5383 has often been used as a prototype of SB(s)b type galaxies, particulary in studies of gas flow. We have therefore set out to complement the existing data with surface photometry, velocity measurements in the bar and a dynamical model.

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.
