Hawai`i Supernova Flows: Bulk Flow Measurements using SNe Ia in the Optical and NIR
Aaron Do, Kaisey S. Mandel, Benjamin J. Shappee +9
The present day peculiar velocity-field was sourced by primordial density fluctuations and sculpted over the lifespan of the Universe. Cosmological models such as CDM make pred…

Constraining cosmological simulations with peculiar velocities: a forward-modeling approach
Aurélien Valade, Noam Libeskind, Daniel Pomarède +4
Numerical simulations are a key tool to decipher the dynamics of gravitation. Yet, they fail to spatially reproduce the Universe we observe, limiting comparison between observation…
