Abstract

3D Spectroscopy of intermediate redshift galactic outflows

Dominik J. Bomans (Astronomical Institute Ruhr-University Bochum)

Galactic outflows and winds are key ingredients for the birth and live of galaxies in the intergalactic medium. Via outflows the halos of galaxies are structured, heated and enriched with heavy elements. Using integral field spectroscopy data (mostly from the CALIFA survey using the CAHA 3.5m/PPAK and some early data from VLT/MUSE) we currently explore the properties and frequency of outflows/winds based on a large, complete sample of intermediate and high mass galaxies in the local universe. Based on the results I will extrapolate to the possibilities of JWST and especially NIRSPEC in IFU mode for studying spatially resolved kinematics and ionization of the emission of galactic outflows and winds at different redshifts. This direct comparision of the same observables between local galaxies and their counterpart at higher redshifts sporting much higher SFR and lower metallicity (and possibly more pronounced infall) will provide input for our detailed understanding of feedback in galaxy formation and evolution. Additionally, I will explore synergies of JWST/NIRSPEC IFU with the E-ELT/HARMONI instrument.
