Kinematics and dynamics of the "superthin" edge-on disk galaxy IC 5249 [PDF]
Astronomy & Astrophysics, 2001 We present spectroscopic observations of the stellar motions in the disk of the superthin edge-on spiral galaxy IC 5249 and re-analyse synthesis observations of the HI.

Kinematics and dynamics of the M 51-type galaxy pair NGC 3893/96 (KPG 302) [PDF]
Astronomy & Astrophysics, 2007 We study the kinematics and dynamics of the M51-type interacting galaxy pair KPG 302 (NGC 3893/96). We analyse the distribution of the dark matter (DM) halo of the main galaxy in order to explore possible differences between DM halos of "isolated ...

Unveiling the Kinematics and Dynamics of Ionized Gas in the Nearby Irregular Galaxy NGC 4449 [PDF]
The Astronomical Journal, 2002 A detailed kinematic analysis of ionized gas in the nearby irregular galaxy NGC 4449 is presented. Observations were conducted in the spectral lines of Hα and [S II].

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.

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.

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 ...

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement. [PDF]
Cogn SciAbstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

Gas Dynamics in the Galaxy: Total Mass Distribution and the Bar Pattern Speed [PDF]
Astrophysical Journal, 2021 Gas morphology and kinematics in the Milky Way contain key information for understanding the formation and evolution of our Galaxy. We present hydrodynamical simulations based on realistic barred Milky Way potentials constrained by recent observations ...

The SAMI galaxy survey: Mass and environment as independent drivers of galaxy dynamics [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The kinematic morphology–density relation of galaxies is normally attributed to a changing distribution of galaxy stellar masses with the local environment. However, earlier studies were largely focused on slow rotators; the dynamical properties of the
