The SAMI Galaxy Survey: Kinematics of Stars and Gas in Brightest Group Galaxies—The Role of Group Dynamics [PDF]

open access: hybridThe Astrophysical Journal, 2021
We study the stellar and gas kinematics of the brightest group galaxies (BGGs) in dynamically relaxed and unrelaxed galaxy groups for a sample of 154 galaxies in the SAMI galaxy survey.

Kinematics and Dynamics of kiloparsec-scale Jets in Radio Galaxies with SKA [PDF]

open access: greenProceedings of Advancing Astrophysics with the Square Kilometre Array — PoS(AASKA14), 2015
We explore the use of SKA to deduce the physical parameters of kiloparsec-scale jet flows in radio galaxies. Jets in Active Galactic Nuclei are relativistic where they are first formed, but their speeds and compositions change as they propagate.

Kinematics and dynamics of the luminous infrared galaxy pair NGC 5257/58 (Arp 240) [PDF]

open access: bronzeAstronomy & 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

The spatial distribution, kinematics, and dynamics of the galaxies in the region of Abell 2634 and 2666 [PDF]

open access: greenThe Astrophysical Journal, 1995
A total of 663 galaxies with known redshifts in a 12 deg x 12 deg field centered on A2634, including 211 new measurements, are used to study in detail the structure of the region.

Morphology, Stellar Kinematics and Dynamics of Barred Galaxies [PDF]

open access: bronzeSymposium - International Astronomical Union, 1983
A brief review is given of the morphology of barred galaxies, following Kormendy (1981, 1982). The features illustrated include bulges, bars, disks, lenses, and inner and outer rings.Most of the paper is devoted to a detailed discussion of the absorption-line velocity field of the prototypical SBO galaxy NGC 936.

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

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2008
Photometry and long-slit spectroscopy are presented for a sample of 6 galaxies with a low surface brightness stellar disc and a bulge The characteris ing parameters of the bulge and disc components were derived by means of a two-dimensional photometric ...

Gas and stellar dynamics in Stephan's Quintet: Mapping the kinematics in a closely interacting compact galaxy group [PDF]

open access: greenAstronomy & Astrophysics, 2021
In nearby compact galaxy groups we can study the complex processes of galaxy interactions at high resolution and obtain a window into a time in the history of the Universe when the galaxies were closely spaced and the intergalactic medium was awash with ...

Two-dimensional kinematics of SLACS lenses - III. Mass structure and dynamics of early-type lens galaxies beyond z ≃ 0.1 [PDF]

open access: bronze, 2011
We combine in a self-consistent way the constraints from both gravitational lensing and stellar kinematics to perform a detailed investigation of the internal mass distribution, amount of dark matter, and dynamical structure of the 16 early-type lens ...

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement. [PDF]

open access: yesCogn Sci
Abstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

Two-dimensional kinematics of SLACS lenses - II. Combined lensing and dynamics analysis of early-type galaxies atz= 0.08-0.33 [PDF]

open access: bronze, 2009
We present the first detailed analysis of the mass and dynamical structure of a sample of six early-type lens galaxies, selected from the Sloan Lens ACS Survey, in the redshift range 0.08 less than or similar to z less than or similar to 0.33.
