The Universe comprises clusters and voids of galaxies and has been shaped by gravity over 13 billion years. Hamiltonian Monte Carlo simulations constrained by observed positions and velocities of galaxies produce maps of the density and velocity field of matter in the local Universe, revealing immense gravitational wells, which can inform future theories of structure formation.

宇宙大尺度结构中的引力井


宇宙由星系团和星系空隙组成，并在 130 亿年的时间里受到重力的影响而形成。受观测到的星系位置和速度约束的哈密顿蒙特卡罗模拟产生了局部宇宙中物质的密度和速度场图，揭示了巨大的引力井，这可以为未来的结构形成理论提供信息。
