Kinematics of Low‐zUltraluminous Infrared Galaxies and Implications for Dynamical Mass Derivations in High‐zStar‐forming Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2005
The kinematic properties of the gaseous and stellar components of 11 ultraluminous infrared galaxies (ULIRGs; 14 nuclei) are investigated by means of integral field spectroscopy (IFS) with the INTEGRAL system and available IR and CO millimeter spectroscopy.

A Dynamical and Kinematic Model of the Galactic Stellar Halo and Possible Implications for Galaxy Formation Scenarios [PDF]

open access: yesThe 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 ...

Structure and dynamics of galaxies with a low surface-brightness disc - I. The stellar and ionized-gas kinematics [PDF]

open access: yesMonthly 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

Shell galaxies: kinematical signature of shells, satellite galaxy disruption and dynamical friction

open access: yes, 2013
Stellar shells observed in many giant elliptical and lenticular as well as a few spiral and dwarf galaxies presumably result from radial minor mergers of galaxies. We show that the line-of-sight velocity distribution of the shells has a quadruple-peaked shape.

From nearby to distant galaxies: kinematical and dynamical studies

open access: yes, 2009
Kinematical studies of low and high redshift galaxies enables to probe galaxy formation and evolution scenarios. Integral field spectroscopy is a powerful tool to study with accuracy nearby galaxies kinematics. Recent observations also gives a new 2D vision of high redshift galaxies kinematics.

Deep Kinematics and Dynamics of Edge-on S0 Galaxies. I. NGC 3115

open access: yes, 1993
As a first step of a program aimed to the detection of dark matter (or radial variations of M/L) in early-type galaxies, we report deep spectroscopic observations of the bulge-dominated edge-on S0 galaxy NGC 3115, made at ESO, La Silla, using EFOSC at the 3.6m telescope and EMMI at NTT.

Distribution and Dynamics of Molecular Gas in the Galaxy M51. III. Kinematics of Molecular Gas [PDF]

open access: yesPublications of the Astronomical Society of Japan, 1997
We present here a study of the dynamics of the molecular gas in the spiral galaxy M51 using CO data obtained with the Nobeyama 45-m telescope. From the distribution of the radial velocity of the CO gas, the velocity components parallel and perpendicular to the spiral arms were determined for each spiral phase.
