The Roadrunner Universe Project: Science<br />

• SDSS-III/BOSS baryon acoustic oscillations simulations and mock catalogs<br />

• SDSS-III Lyman-alpha runs, signature of BAO scale in Lyman-alpha forest<br />

• JDEM weak lensing<br />

• High-resolution simulations for dark matter searches<br />

• LSST simulations for a variety of projects (weak lensing, clusters, BAO)<br />

• Large-volume cluster simulations and large-scale flows<br />

• Addition of new physics:<br />

‣ Self-consistent dark energy models and inclusion of dark energy fluctuations (LSST ISW)<br />

‣ Nonparametric w(z) simulations<br />

‣ Calibration of baryonic effects in weak lensing<br />

‣ New code for modified gravity (cosmological PPN)<br />

‣ More general primordial fluctuations (running of spectral index, non-Gaussianity, warm/nonthermal dark<br />

matter)<br />

‣ Nonlinear clustering of neutrinos<br />

‣ Your favorite idea here --<br />

• Extension of Calibration Framework to address expanded “physics space” and smaller<br />

errors<br />
