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…
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…
