An ultralight scalar boson with mass $m_1\simeq 10^{-22}\mathrm{eV}$ is gaining credence as a Dark Matter (DM) candidate that explains the dark cores of dwarf galaxies as soliton waves. Such a boson is naturally interpreted as an axion generic in String Theory, with multiple light axions predicted in this context. We examine the possibility of soliton structures over a wide range of scales, accounting for galaxy core masses and the common presence of nuclear star clusters. We present a diagnostic soliton core mass–radius plot that provides a global view, indicating the existence of an additional axion with mass $m_2\simeq 10^{-20}\mathrm{eV}$, with the possibility of a third axion with mass $m_3\gtrsim 0.5\times 10^{-18}\mathrm{eV}$. We also argue that the relative mass densities measured for these axions are consistent with their cosmological production via the mis-alignment mechanism.

超轻质标量玻色子 ${米}_{\mathrm{1个}}\simeq \mathrm{1个}{0}^{-22}\mathrm{电子伏特}$作为暗物质（DM）候选者而获得了信任，该候选者将矮星系的暗核解释为孤子波。这样的玻色子自然被解释为弦理论中的通用轴，在这种情况下可以预测出多个轻轴。我们检查了范围广泛的尺度上的孤子结构的可能性，其中考虑了星系核心质量和核星团的普遍存在。我们提出了诊断孤子核心质量半径图，该图提供了一个整体视图，表明存在附加的质量轴${米}_2\simeq \mathrm{1个}{0}^{-20}\mathrm{电子伏特}$，有可能发生第三次弥撒 ${米}_3\gtrsim 0。5\times \mathrm{1个}{0}^{-\mathrm{18岁}}\mathrm{电子伏特}$。我们还认为，针对这些轴的相对质量密度通过失准机制与它们的宇宙生产相一致。
