Witnessing the Early Growth and Life Cycle of Galaxies with KMOS3D

Near-infrared integral field unit (IFU) spectrographs are powerful tools for investigating galaxy evolution. We report on our recently completed multi-year KMOS3D survey of Halpha, [NII] and [SII] line emission of galaxies at redshift z ~ 0.7 - 2.7 with the K-band Multi-Object Spectrograph (KMOS) at...

Zusammenfassung:Near-infrared integral field unit (IFU) spectrographs are powerful tools for investigating galaxy evolution. We report on our recently completed multi-year KMOS3D survey of Halpha, [NII] and [SII] line emission of galaxies at redshift z ~ 0.7 - 2.7 with the K-band Multi-Object Spectrograph (KMOS) at the Very Large Telescope (VLT). With deep observations of 745 targets spanning over two orders of magnitude in galaxy mass, five billion years of cosmic time, and all levels of star formation, KMOS3D provides an unparalleled population-wide census of spatially-resolved kinematics, star formation, outflows and nebular gas conditions. The dataset sheds new light on the physical mechanisms driving the early growth and lifecycle of galaxies, and provides a rich legacy for the astronomical community.
