Galactic Superwinds

Date & Time


Schloss Elmau
In Elmau 2, 82493 Krün Germany

Andrew Benson, Carnegie Institution for Science
Juna Kollmeier, Carnegie Institution for Science

The third and final Symposium on Galactic Superwinds will revisit the physics of birthing, launching and sustaining galactic superwinds in cosmological calculations. Since the first symposium in 2014, there has been substantial progress in understanding the multiphase wind medium both theoretically and observationally.

In the final symposium, organizers Kollmeier and Benson aim to critically examine the remain uncertainties associated with galactic winds, summarize the progress that has been made, and develop a program of research to continue advancing this field.
