Stellar kinematics of barred galaxies
نویسنده
چکیده
I show that the counter-rotating core of the barred galaxy NGC5728 could be explained by the internal dynamics of the bar. This supports the idea that the nuclear bar is counter-rotating.

2d Stellar Kinematics of Nuclear Bars
We just started an observational program to obtain 2D kinematics of nuclear bars, to be compared to N body simulations of single and double-barred galaxies. We have started a program to study the kinematics of double-barred galaxies using the Integral Field Spectrograph OASIS (CFHT). Stellar bidimensional velocity fields obtained with OASIS are compared with N body + SPH simulations, to constra...
متن کاملObservable Properties of Double-barred Galaxies in N-body Simulations
Although at least one quarter of early-type barred galaxies host secondary stellar bars embedded in their large-scale primary counterparts, the dynamics of such double barred galaxies are still not well understood. Recently we reported success at simulating such systems in a repeatable way in collisionless systems. In order to further our understanding of double-barred galaxies, here we charact...

Significant fraction of barred galaxies hosts secondary bar-like structures on optical and NIR images. The circumnuclear dynamics of double-barred objects are still not well understood, observational data concerning kinematics are incomplete and inconsistent. In order to compare the simulations results with observations, we have started new spectroscopic studying of stellar kinematics in lentic...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملspectroscopy of double - barred galaxies
The first results of the observational program of the study of 2D-kinematics in double-barred galaxies are presented. We show that, for the main part of the sample, the inner bars do not affect the circumnu-clear stellar kinematics. Therefore, they are not dynamically decoupled structures. Various types of non-circular gas motion were found in many galaxies. The analysis of the ground-based and...
