The Role Of Mergers In Galaxy Formation

Résumé

The combination of high spatial resolution from space and 3D spectroscopy from ground is a remarkable tool to dissect distant galaxies and their internal motions. Combining HST and VLT instruments, it has robustly captured the evolution of the Hubble Sequence since the last 8 billion years. The disk (re)formation in Milky Way-mass galaxies may occur during the last 8-10 Gyr, which is now widely reproduced in recent cosmological simulations. The impact of mergers has been also re-evaluated solving the long-standing problem of the disk survival and perhaps, the angular momentum crisis.

Here we present our latest results based on the recent 3D spectroscopic survey (here KMOS-3D). It evidences that nearly 60% of z 1 galaxies are within a process of merger/interaction, while only a third are isolated, virialized disks.
