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…
Single CO peak in the double bar galaxy NGC 5850
S. Leon, F. Combes, D. Friedli
NGC 5850 is a prototype of double-barred galaxy (Friedli et al. 1996) classified as SBb(sr) I-II (Higdon et al. 1998; Prieto et al. 1997). This kind of system is primordial to unde…
Birth, Aging, and Death of Galactic Bars
D. Friedli
The life of disk galaxies is likely punctuated with the birth (spontaneous or induced), the aging (quick or slow), and the death (sudden or progressive) of bars. These events are r…
Single CO Peak in NGC 5850
S. Leon, F. Combes, D. Friedli
NGC 5850 is a prototype of double-barred galaxy (Friedli et al. 1996) classified as SBb(sr) I-II (Higdon et al. 1998; Prieto et al. 1997). This kind of system is primordial to unde…
Mixing and Transfer of Elements by Triaxiality
D. Friedli
Various large-scale processes induced by triaxial potentials and able to alter stellar and gaseous abundance profiles are reviewed. In particular, strong bars can quickly and effic…
ISOCAM images at 6.75 and 15 microns: the circumnuclear region of NGC 4321 (M 100)
H. Wozniak, D. Friedli, L. Martinet +1
We present ISOCAM images (1.5"/px) in the LW2 (6.75 microns) and LW3 (15 microns) broad band filters of the circumnuclear starburst of NGC 4321 (M 100). A detailed comparison with…
First Results from ISOCAM Images of Circumnuclear Starbursts in Barred Galaxies
H. Wozniak, D. Friedli, L. Martinet +1
For a sample of ten nearby barred galaxies, images at 6.75\um and 15\um of circumnuclear starbursts are being taken by ISOCAM on board of the ISO satellite. We first recall the mai…
Bar strength and star formation activity in late-type barred galaxies
L. Martinet, D. Friedli
With the prime aim of better probing and understanding the intimate link between star formation activity and the presence of bars, a representative sample of 32 non-interacting lat…
Disc galaxies with multiple triaxial structures. II. JHK surface photometry and numerical simulations
D. Friedli, H. Wozniak, M. Rieke +2
We present detailed JHK surface photometry with ellipse fits of 13 galaxies selected from previous optical observations as likely candidates for having a secondary bar or a triaxia…
Counter-rotating bars within bars
D. Friedli
The dynamical stability and evolution of disc galaxies with different disc thickness as well as various fraction and concentration of stellar counter-rotation is investigated with…
3D Barred Model of the Milky Way Including Gas
R. Fux, D. Friedli
We present a 3D N-body simulation of the Milky Way including 4*10^5 star- and dark-like particles and 2*10^4 gas particles, initially distributed according to an axisymmetric, obse…
