Approaching the dynamics of hot nucleons in supernovae
M. Liebendoerfer, U. -L. Pen, C. Thompson
All recent numerical simulations agree that stars in the main sequence mass range of 9-40 solar masses do not produce a prompt hydrodynamic ejection of the outer layers after core…
Beating Lensing Cosmic Variance with Galaxy Tomography
Ue-Li Pen
I discuss the use of cross correlations between galaxies with distance information and projected weak lensing dark matter maps to obtain a fully three dimensional dark matter map a…
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…
The intergalactic medium temperature and Compton y parameter
Pengjie Zhang, Ue-Li Pen, Hy Trac
(Abridged) The precision modeling of the thermal Sunyaev Zeldovich (SZ) effect and future high accuracy measurements will provide a powerful way to constrain the thermal history of…
