Kinematical Fluctuations Vary with Galaxy Surface Mass Density
The Astrophysical Journal Letters, 2023 The Galaxy inner parts are generally considered to be optically symmetric, as well as kinematically symmetric for most massive early-type galaxies. At the lower-mass end, many galaxies contain lots of small patches in their velocity maps, causing their ...

The impact of galaxy harassment on the globular cluster systems of early-type cluster dwarf galaxies
, 2012 The dynamics of globular cluster systems (GCSs) around galaxies are often used to assess the total enclosed mass, and even to constrain the dark matter distribution.

Chemo-dynamical Evolution of Galaxies
, 2023 Stars are fossils that retain the history of their host galaxies. Elements heavier than helium are created inside stars and are ejected when they die. From the spatial distribution of elements in galaxies, it is therefore possible to constrain the physical processes during galaxy formation and evolution.

Dynamical stability and galaxy evolution in LSB disk galaxies [PDF]
AIP Conference Proceedings, 1997 We demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global bar modes. However, they may be only marginally stable against local disk instabilities. We simulate a collision between an LSB and HSB galaxy and find that, while the HSB galaxy forms a strong bar, the ...

Influence of Magnetic Fields on the Gas Rotation in the Galaxy NGC 6946
The Astrophysical Journal, 2023 Magnetic fields can play an important role in the energy balance and formation of gas structures in galaxies. However, their dynamical effect on the rotation curve of galaxies is immensely unexplored.

Overconstrained dynamics in galaxy redshift surveys
, 2001 The least-action principle (LAP) method is used on four galaxy redshift surveys to measure the density parameter Omega_m and the matter and galaxy-galaxy power spectra. The datasets are PSCz, ORS, Mark III and SFI.

Galaxy Dynamics Predictions in the Nonsymmetric Gravitational Theory [PDF]
, 1994 In the weak field approximation, the nonsymmetric gravitational theory (NGT) has, in addition to the Newtonian gravitational potential, a Yukawa-like potential produced by the exchange of a spin $1^+$ boson between fermions.

Galaxy groups and the modified dynamics
, 1998 I estimate Modified-Dynamics (MOND), median M/L values for recently published catalogues of galaxy groups. While the median, Newtonian M/L values quoted for these catalogues are 110-200 solar units, the corresponding values for MOND are less than 10 ...
