Testing the nature of S0 galaxies using planetary nebula kinematics in NGC 1023 [PDF]
, 2007 We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer disc kinematics to its progenitor, while an S0 formed in a minor merger ...

Galaxy Zoo: kinematics of strongly and weakly barred galaxies
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACTWe study the bar pattern speeds and corotation radii of 225 barred galaxies, using integral field unit data from MaNGA and the Tremaine–Weinberg method. Our sample, which is divided between strongly and weakly barred galaxies identified via Galaxy Zoo, is the largest that this method has been applied to.

The Astrophysical Journal, 2023 We use the conjugate angle of radial action ( θ _R ), the best representation of the orbital phase, to explore the “midplane,” “north branch,” “south branch,” and “Monoceros area” disk structures that were previously revealed in the LAMOST K giants.

Kinematical data on early-type galaxies. I. [PDF]
Astronomy and Astrophysics Supplement Series, 1997 We present new kinematical data for a sample of 38 early-type galaxies. Rotation curves and velocity-dispersion profiles are determined for 32 objects, while the central velocity dispersions are given for the whole sample. This is our second paper in a series devoted to the presentation of kinematical data on elliptical and S0 galaxies, derived from ...

Kinematics of simulated galaxies II: Probing the stellar kinematics of galaxies out to large radii [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We investigate the stellar kinematics of a sample of galaxies extracted from the hydrodynamic cosmological Magneticum Pathfinder simulations out to five half-mass radii. We construct differential radial stellar spin profiles quantified by the observationally widely used λ and the closely related (V/σ) parameters.

KINEMATICS OF M51-TYPE INTERACTING GALAXIES [PDF]
The Astronomical Journal, 2016 ABSTRACT We present a kinematic catalog for 21 M51-type galaxies. It consists of radial velocity distributions observed with long-slit spectroscopy along different position angles, for both the main and satellite components. We detect deviations from circular motion in most of the main galaxies of each pair, due to the gravitational ...

Measuring galaxy potentials using shell kinematics [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We show that the kinematics of the shells seen around some elliptical galaxies provide a new, independent means for measuring the gravitational potentials of elliptical galaxies out to large radii. A numerical simulation of a set of shells formed in the merger between an elliptical and a smaller galaxy reveals that the shells have a characteristic ...

The Astrophysical Journal, 2023 Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which
