A new method of measuring the peculiar velocity power spectrum
We show that by directly correlating the cluster kinetic Sunyaev Zeldovich (KSZ) flux, the cluster peculiar velocity power spectrum can

Collective motion of self-propelled particles: kinetic phase transition in one dimension
We demonstrate that a system of self-propelled particles (SPP) exhibits spontaneous symmetry breaking and self-organization in one dimension, in contrast

Comment on a Paper by Fang, Huang, and Wu
Before decoupling in the early universe, the tightly coupled photon/electron gas underwent acoustic oscillations. These oscillations should be visible today

Convergence of Passive Scalars in Ornstein-Uhlenbeck Flows to Kraichnan's Model
We prove that the passive scalar field in the Ornstein-Uhlenbeck velocity field with wave-number dependent correlation times converges, in the

Extensions to the Kompaneets Equation and Sunyaev-Zel'dovich Distortion
Analytical expressions are presented for relativistic corrections to the Kompaneets equation and the Sunyaev-Zel'dovich y-distortion. The latter provides a convenient
