A forming, dust enshrouded disk at z=0.43: the first example of a late type disk rebuilt after a major merger?
F. Hammer, H. Flores, Y. B. Yang +4
Abreg: By combining HST/UDF imagery with kinematics from VLT/GIRAFFE we derive a physical model of distant galaxy J033245.11-274724.0 in a way similar to what can be done in the ne…
A giant bar induced by a merger event at z=0.4?
Sébastien Peirani, Francois Hammer, Hector Flores +2
(Aims) We present a physical model of the formation of J033239.72-275154.7, a galaxy observed at z=0.41 and characterized by a big young bar of size 6 kpc. The study of this system…
IMAGES-III: The evolution of the Near-Infrared Tully-Fisher relation over the last 6 Gyr
M. Puech, H. Flores, F. Hammer +22
Using the multi-integral field spectrograph GIRAFFE at VLT, we have derived the K-band Tully-Fisher relation (TFR) at z~0.6 for a representative sample of 65 galaxies with emission…
IMAGES I. Strong evolution of galaxy kinematics since z=1
Y. Yang, H. Flores, F. Hammer +20
(abbreviated) We present the first results of the ESO large program, ``IMAGES'' which aims at obtaining robust measurements of the kinematics of distant galaxies using the multi-IF…
The direct oxygen abundances of metal-rich galaxies derived from electron temperature
Y. C. Liang, F. Hammer, S. Y. Yin +3
We aim to derive the electron temperature Te in the gas of metal-rich star-forming galaxies, which can be obtained from their ratios of auroral lines [O II]7320,7330 to nebular lin…
