A wavelike solution for the non-relativistic universal dark matter (wave-DM) is rapidly gaining interest, following pioneering simulations of cosmic structure as an interference pattern of coherently oscillating bosons. A prominent solitonic standing wave is predicted at the center of every galaxy, representing the ground state solution of the coupled Schrödinger–Poisson equations, and it has been identified with the wide, kpc scale dark cores of common dwarf-spheroidal galaxies. A denser soliton is predicted for Milky Way sized galaxies where momentum is higher, so the de Broglie scale of the soliton is smaller, pc, of mass . Here we show the central motion of bulge stars in the Milky Way implies the presence of such a dark core, where the velocity dispersion rises inversely with radius to a maximum of km/s, corresponding to an excess central mass of within pc, favoring a boson mass of . This quantitative agreement with such a unique and distinctive prediction is therefore strong evidence for a light bosonic solution to the long standing Dark Matter puzzle.

暗暗孤子核心的动力学证据 银河系
在将宇宙结构作为相干振荡玻色子的干涉图样进行开创性模拟之后,非相对论通用暗物质(wave-DM)的波动解决方案迅速引起人们的兴趣。在每个星系的中心都预测到一个显着的孤子驻波,代表着耦合的Schrödinger-Poisson方程的基态解,并且它已被常见的矮球状星系的宽kpc级暗核所识别。对于动量较高的银河系星系,预计其孤子会更密集,因此德布罗意的孤子尺度较小, pc,质量 。在这里,我们显示出银河系中凸起恒星的中心运动暗示着这样一个暗核的存在,其中速度色散随半径成反比地增加,最大为 km / s,对应于多余的中心质量 内 pc,偏爱玻色子 。因此,这种具有如此独特而独特的预测的定量协议,为长期存在的暗物质难题提供了轻质的玻色解的有力证据。
