来自不育中微子发射的延迟脉冲星反冲

Delayed pulsar kicks from the emission of sterile neutrinos

Alexander Kusenko, Bhabani Prasad Mandal, Alok Mukherjee

摘要:

观测到的中子星的速度表明,质量为几keV的无菌中微子可能是从冷却的中子星中发射出来的。同样的无菌中微子可以构成宇宙学暗物质的全部或部分。中微子驱动的反冲可以根据质量和混合角表现出延迟,这可以与脉冲星数据进行比较。我们讨论了不育中微子参数的允许范围,与最新的宇宙学和X射线的界限,这可以解释脉冲星踢不同的延迟时间。

英文摘要:

The observed velocities of pulsars suggest the possibility that sterile neutrinos with mass of several keV are emitted from a cooling neutron star. The same sterile neutrinos could constitute all or part of cosmological dark matter. The neutrino-driven kicks can exhibit delays depending on the mass and the mixing angle, which can be compared with the pulsar data. We discuss the allowed ranges of sterile neutrino parameters, consistent with the latest cosmological and X-ray bounds, which can explain the pulsar kicks for different delay times.
