Stellar kinematics of barred galaxies
Herve Wozniak
I show that the counter-rotating core of the barred galaxy NGC 5728 could be explained by the internal dynamics of the bar. This supports the idea that the nuclear bar is counter-r…
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…
Starbursts in Barred Spiral Galaxies. II. Molecular and Optical Study of Three Wolf-Rayet Galaxies
T. Contini, H. Wozniak, S. Considere +1
We have searched for dense molecular gas in three barred spiral galaxies with young starbursts, NGC 3049, 5430 and 6764, which are known Wolf-Rayet galaxies. We detected HCN in the…
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…
Comparison of the dense molecular gas in the LINER galaxy NGC 6764 and in the Wolf-Rayet galaxy NGC 5430
T. Contini, H. Wozniak, E. Davoust +1
We compare the dense molecular gas content in two barred spiral galaxies, NGC 6764 (classified LINER) and NGC 5430 (a Wolf-Rayet galaxy). We find a significant difference in the pr…
