The growth rate of surface area measure for noncompact convex sets with prescribed asymptotic cone
Vadim Semenov, Yiming Zhao
The Minkowski problem for a class of unbounded closed convex sets is considered. This is equivalent to a Monge-Ampère equation on a bounded convex open domain with possibly non-in…

Entrainment of Hot Gas into Cold Streams: The Origin of Excessive Star-formation Rates at Cosmic Noon
Han Aung, Nir Mandelker, Avishai Dekel +3
We explore the evolution of cold streams from the cosmic web that feed galaxies through their shock-heated circumgalactic medium (CGM) at cosmic noon, . In addition to…
