The Galaxy Baryon Cycle: Gas, Star-Formation, and Feedback

The formation and evolution of galaxies are governed by the continuous flow of gas in and out of the system. Galaxies accrete fresh gas from the environment, convert it into stars, and release enriched material into the ISM via stellar winds, supernova explosions, and AGN feedback. I will present multiwavelength observational studies to characterize the galaxy baryon cycle and test galaxy formation models. In particular, I will focus on (1) the connection between cold gas, dust, and star-formation activity, exploiting the synergy between millimeter observations and optical spectroscopy (e.g., the ALMAQUEST survey), and (2) the demographics of multi-phase galactic outflows at both low and high z, using optical and NIR spectroscopy (e.g., the KLEVER survey).

Brief CV of Dr. Alice Concas:

Alice Concas currently holds a fellowship position at the European Southern Observatory (ESO), conducting research in the field of galaxy formation and evolution. She completed her bachelor’s and master’s studies at the University of Bologna in 2013 and obtained her Ph.D. in astronomy at the Excellence Cluster Universe and Technical University of Munich, Germany, in 2018. During the period 2019-2020, she was a postdoc researcher at the Kavli Institute for Cosmology at the University of Cambridge, UK. After a brief postdoc at the University of Florence, she joined ESO in 2021, where she is involved in the development of the Extremely Large Telescope.
