Cosmology and Astrophysics with Galaxy Clusters
ISAS astro seminar
Prof. Daisuke Nagai (Yale) Thursday December 25, 11:00 am 1134 : Bldg-A 1F Nyusatsu room
Title: Cosmology and Astrophysics with Galaxy Clusters Abstract: Galaxy clusters are the most recently formed cosmological objects in the universe, making them ideal for studying the interplay between cosmology and baryonic physics in structure formation. Understanding their formation and growth requires not only an understanding of the baryonic physics behind gas cooling, star and black hole formation, and feedback processes, but also the detailed dynamics of how gas accretes from the cosmic filaments onto the virialization regions in the outskirts of galaxy clusters throughout their lifetime. Recent X-ray and microwave observations have revealed detailed thermodynamic structure of the hot X-ray emitting plasma from their cores to the virial radii, making comparisons of baryonic component in simulations to observations a strong cosmological probe. In this talk, I will review recent advances in our understanding of cluster astrophysics and discuss future prospects, opportunities and challenges (including upcoming measurement of turbulent gas motions with ASTRO-H) a for the use of galaxy clusters as a precision cosmological probe.
