A large thermal energy reservoir in the nascent intracluster medium at a redshift of 4.3
Dazhi Zhou, Scott Chapman, Manuel Aravena +21
Most baryons in present-day galaxy clusters exist as hot gas (), forming the intracluster medium (ICM). Cosmological simulations predict th…
An Image-Plane Approach to Gravitational Lens Modeling of Interferometric Data
