X-raying the chemistry and evolution of the large-scale structure by Dr Aurora Simionescu
Abstract: X-ray spectroscopy is one of our main tools for studying the physical and chemical properties of the intracluster, intragroup, circumgalactic, and intergalactic media, and understanding their connection, interaction, and evolution. This gives us invaluable insight into physical processes spanning an enormous range of scales: nuclear reactions in the core of a star produce chemical elements that may later be expelled from the host galaxy by jets launched near the event horizon of a supermassive black hole (SMBH); these metals roam through the cosmos and can then accrete onto a different halo, many millions of light years away. I will summarize our current view of these processes based on past and present X-ray observations, and then discuss how sensitive wide-area surveys as well as the higher spectral resolution integral field spectroscopy capabilities on future satellites will push our study of gaseous haloes to new frontiers.
