Project title: SWINGThe role of superwinds in the life cycle of galaxies 


Superwinds are galaxy wide, energetic and mass loaded outflows of gas. Superwinds are common at all redshifts, and they may affect an important fraction of the baryons in the universe. Superwinds may be the long-sought vectors of AGN radiative feedback, and the dominant feedback mechanism for galaxy growth; but how do they work?

Conclusive evidence of superwinds affecting galaxy structure and evolution is still ahead of us, due to the biases and paucity of current studies. A systematic investigation is needed to make progress.

SWING aims at building on firm grounds our understanding of the impact of superwinds in the life cycle of galaxies through cosmic time. SWING is designed to carry out the first statistically sound investigation of superwinds by combining the insights provided by the detailed study of the interplay between superwinds and ISM/CGM in individual sources, with the demographic information obtained on unbiased samples from z=0 to 4.

This empirical approach is implemented into four work-packages (WP):

– Demography and scaling relations between superwinds and galaxy/AGN physical properties, along cosmic time with the smallest systematic errors (WP-STAT)

– Physical (WP-MAP) and chemical (WP-CHEM) effects of superwinds on the ISM

– Impact of superwinds on the galaxy ecosystem at the main epoch of galaxy and AGN assembly (WP-ENV).

These will not only lead to a better understanding of the role of superwinds in the evolution of galaxies, but will also be instrumental to inform the sub-grid treatment of superwinds in detailed cosmological hydrodynamic simulations of galaxy formation, carried out by the group of computational cosmology at OATs, which will provide the theoretical interpretative and predictive framework. The main SWING breakthroughs are the use of unbiased blind samples, and the first systematic application to the extragalactic scenario of astrochemistry techniques previously used on Milky Way studies.
