Giant outflows in z~2 radio galaxies: The smoking gun of AGN feedback in the early universe
N. P. H. Nesvadba
AGN feedback is now a major component of models of galaxy evolution. Using near-infrared imaging spectroscopy on the VLT we identify kpc-sized outflows of few x 10^10 M_s of ionize…
CO line emission in the halo of a radio galaxy at z=2.6
N. P. H. Nesvadba, R. Neri, C. De Breuck +6
We report the detection of luminous CO(3-2) line emission in the halo of the z=2.6 radio galaxy (HzRG) TXS0828+193, which has no detected counterpart at optical to mid-infrared wav…
Images IV: Strong evolution of the oxygen abundance in gaseous phases of intermediate mass galaxies since z=0.8
M. Rodrigues, F. Hammer, H. Flores +22
Intermediate mass galaxies (logM(Msun)>10) at z~0.6 are the likeliest progenitors of the present-day numerous population of spirals. There is growing evidence that they have evolve…
Observations and modelling of a clumpy galaxy at z=1.6: Spectroscopic clues to the origin and evolution of chain galaxies
F. Bournaud, E. Daddi, B. G. Elmegreen +7
We investigate the properties of a clump-cluster galaxy at redshift 1.57. The morphology of this galaxy is dominated by eight star-forming clumps in optical observations, and has p…
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…
