GRACOS: Scalable and Load Balanced P3M Cosmological N-body Code
Alexander Shirokov, Edmund Bertschinger
We present a parallel implementation of the particle-particle/particle-mesh (P3M) algorithm for distributed memory clusters. The GRACOS (GRAvitational COSmology) code uses a hybrid…
Kinetic theory of polarization in the Sunyaev-Zeldovich effect
Jamie Portsmouth, Edmund Bertschinger
We apply the coherency tensor formalism to the calculation of the spectral distortions imprinted in the intensity and polarization of the cosmic microwave background radiation due…
Cosmological Perturbation Theory and Structure Formation
Edmund Bertschinger
These lecture notes discuss several topics in the physics of cosmic structure formation starting from the evolution of small-amplitude fluctuations in the radiation-dominated era.…
Cosmological Dynamics
Edmund Bertschinger
This is a set of lecture notes basd on the lectures on cosmological dynamics given by E. Bertschinger at Les Houches in August 1993. The contents include elementary mechanics in co…
Nonlinear Effects due to the Coupling of Long-Wave Modes
Bhuvnesh Jain, Edmund Bertschinger
The cosmological fluid equations are used to study the nonlinear mode coupling of density fluctuations. We find that for realistic cosmological spectra there is a significant contr…
Kinematical and Dynamical Approaches to Gravitational Instability
Edmund Bertschinger
This paper reviews the essential physics of gravitational instability in a Robertson-Walker background spacetime. Three approaches are presented in a pedagogical manner, based on (…
