The HalfDome Cosmological Simulations (https://halfdomesims.github.io/) are tailored to the joint analysis of ongoing and upcoming cosmological surveys such as DESI, PFS, Rubin LSST, Euclid, SPHEREx, Roman, Simons Observatory, CMB-S4, and LiteBIRD. These surveys have the potential to reach groundbreaking discoveries on multiple fronts such as the neutrino mass, dark energy, and inflation. However, these key science goals require the joint analysis of multiple datasets to break parameter degeneracies and calibrate systematics. By modeling the multi-wavelength observables in a correlated manner, our simulations are designed to enable such analyses.
We are a diverse team of experts in the worlds of the cosmic microwave background, large-scale structure, numerical simulations, and machine learning. We plan to release our simulations and codes to the public, with continued future updates. If you are interested in collaborating with us, please reach out: halfdomesims@gmail.com.
