The Dynamics of the Dwarf Elliptical Galaxy FS 76: Bridging the Kinematic Dichotomy between Elliptical and Dwarf Elliptical Galaxies [PDF]
The Astrophysical Journal, 2001 We present major- and minor-axis kinematics out to ˜2 half-light radii for the bright (MB = -16.7) dwarf elliptical galaxy (dE) FS 76, a member of the NGC 5044 group. Its velocity dispersion is 46 ‘ 2 km s-1 in the center and rises to 70 ‘ 10 km s-1 at half-light radius. Beyond 1Re, the dispersion starts to fall again.

A Dynamical and Kinematic Model of the Galactic Stellar Halo and Possible Implications for Galaxy Formation Scenarios [PDF]
The Astrophysical Journal, 1997 We re-analyse the kinematics of the system of blue horizontal branch field (BHBF) stars in the Galactic halo (in particular the outer halo), fitting the kinematics with the model of radial and tangential velocity dispersions in the halo as a function of galactocentric distance r proposed by Sommer-Larsen, Flynn & Christensen (1994), using a much ...

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 ...

Self-consistent Bulge/Disk/Halo Galaxy Dynamical Modeling Using Integral Field Kinematics [PDF]
The Astrophysical Journal, 2017 Abstract We introduce a method for modeling disk galaxies designed to take full advantage of data from integral field spectroscopy (IFS). The method fits equilibrium models to simultaneously reproduce the surface brightness, rotation, and velocity dispersion profiles of a galaxy.

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
