Dynamics of embedded bars and the connection with AGN. I. ISAAC/VLT stellar kinematics
E. Emsellem, D. Greusard, F. Combes +4
We present new stellar kinematical profiles of four galaxy hosts of active galactic nuclei, using the CO bandhead around 2.3 micron with the ISAAC/VLT spectrograph. We find that th…
Gaseous Disks of Spiral Galaxies: Arms and Rings
Edward Liverts, Evgeny Griv, Michael Gedalin +2
An improved linear stability theory of small-amplitude oscillations of a self-gravitating, infinitesimally thin gaseous disk of spiral galaxies has been developed. It was shown tha…
Formation of the Planetary Sequence in a Highly Flattened Disk of Frequently Colliding Planetesimals
Evgeny Griv, Michael Gedalin, Edward Liverts +2
The kinetic theory is used to study the evolution of the self-gravitating disk of planetesimals. The effects of frequent collisions between planetesimals are taken into account by…
Molecular Gas in the Powerful Radio Galaxies 3C~31 and 3C~264: Major or Minor Mergers?
J. Lim, S. Leon, F. Combes +1
We report the detection of CO~() and CO~() emission from the central regions (--) of the two powerful radio galaxies 3C~31…
Determining the Geometry and the Cosmological Parameters of the Universe through SZE Cluster Counts
Zuhui Fan, Tzihong Chiueh
We study Sunyaev-Zeldovich Effect (SZE) cluster counts in different cosmologies. It is found that even without the full knowledge of the redshift distribution of SZE clusters, one…
Weakly nonlinear theory of the Jeans instability in disk galaxies of stars
Evgeny Griv, Michael Gedalin, David Eichler +1
The reaction of collective oscillations excited in the interaction between aperiodically growing Jeans-type gravity perturbations and stars of a rapidly rotating disk of flat galax…
