Observational Evidence for Extra Dimensions from Dark Matter
Bo Qin, Ue-Li Pen, Joseph Silk
Recent astronomical observations of systems of dark matter, which have been cited as providing possible support for self-interacting cold dark matter, may provide evidence for the…
Searching for Early Ionization with the Primeval Structure Telescope
Jeff Peterson, Ue-Li Pen, Xiang-Ping Wu
The Primeval Structure Telescope (PaST), will be used search for and study the era the of the first luminous objects, the epoch of reionization. The first stars ionized the gas aro…
Out-of-Core Hydrodynamic Simulations for Cosmological Applications
Hy Trac, Ue-Li Pen
We present an out-of-core hydrodynamic code for high resolution cosmological simulations that require terabytes of memory. Out-of-core computation refers to the technique of using…
Towards optimal parallel PM N-body codes: PMFAST
Hugh Merz, Ue-Li Pen, Hy Trac
We present a new parallel PM N-body code named PMFAST that is freely available to the public. PMFAST is based on a two-level mesh gravity solver where the gravitational forces are…
