The effects of ram-pressure stripping on the internal kinematics of simulated spiral galaxies [PDF]
, 2008 We investigate the influence of ram-pressure stripping on the internal gas kinematics of simulated spiral galaxies. Additional emphasis is put on the question of how the resulting distortions of the gaseous disc are visible in the rotation curve and/or ...

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 ...

Discovery of Multi-Phase Cold Accretion in a Massive Galaxy at z=0.7 [PDF]
, 2012 We present detailed photo+collisional ionization models and kinematic models of the multi-phase absorbing gas, detected within the HST/COS, HST/STIS, and Keck/HIRES spectra of the background quasar TON 153, at 104 kpc along the projected minor axis of a ...

Mapping the inner regions of the polar disk galaxy NGC4650A with MUSE [PDF]
, 2015 [abridged] The polar disk galaxy NGC4650A was observed during the commissioning of the MUSE at the ESO VLT to obtain the first 2D map of the velocity and velocity dispersion for both stars and gas.

The benchmark black hole in NGC 4258: dynamical models from high-resolution two-dimensional stellar kinematics [PDF]
, 2015 NGC 4258 is the galaxy with the most accurate (maser-based) determination for the mass of the supermassive black hole (SMBH) in its nucleus. In this work we present a two-dimensional mapping of the stellar kinematics in the inner 3.0 x 3.0 arcsec = 100 x

Mapping the Kinematically Decoupled Core in NGC 1407 with MUSE
, 2018 Studies of the kinematics of NGC 1407 have revealed complex kinematical structure, consisting of the outer galaxy, an embedded disc within a radius of $\sim60$ arcsec, and a kinematically decoupled core (KDC) with a radius of less than 30arcsec. However,

Kinematics of the outer pseudorings and the spiral structure of the Galaxy [PDF]
, 2008 The kinematics of the outer rings and pseudorings is determined by two processes: the resonance tuning and the gas outflow. The resonance kinematics is clearly observed in the pure rings, while the kinematics of the gas outflow is manifested itself in ...

Spectral decomposition of the stellar kinematics in the polar disk galaxy NGC 4650A [PDF]
, 2014 Context. The prototype of Polar Ring Galaxies NGC 4650A contains two main structural components, a central spheroid, which is the host galaxy, and an extended polar disk.

Kinematics of a high-redshift galaxy: A case study [PDF]
Serbian Astronomical Journal, 2000 A kinematics of a z = 2.81 galaxy toward bright QSO 0528-250, as inferred from the absorption spectroscopy is discussed. There are sufficient arguments for a far-reaching conclusion that we are observing an older, uninvolved version of the local Galactic
