论文摘要
由于其高磁场和血浆密度，脉冲星为超出标准模型（BSM）物理学的测试提供了出色的实验室。当轴或轴状颗粒（ALP）与脉冲星足够接近时，它们可以共鸣转换为光子，从而产生戏剧性的电磁信号。我们讨论了从轴结合构型中检测此类信号，与脉冲星磁层碰撞的可能性。我们发现，除了最密集的轴恒星（$ \ textit {oscillons} $）以外的所有内容都被潮汐破坏了，然后再进行共振转换。可以有效地转换为光子，从而导致明亮的短暂无线电闪光灯。使用现有（非常大的阵列和Lofar）以及即将到来的（平方公里阵列）无线电任务观察银河膨胀的可能性有可能检测到在$ $ m_a \ in \ in \左[0.1 \μ\μ\ text {ev ev}，200 \μ\μ\ \μ\ \ text {ev ev} \ right的范围内的轴质量的事件，即使
Due to their high magnetic fields and plasma densities, pulsars provide excellent laboratories for tests of beyond Standard Model (BSM) physics. When axions or axion-like particles (ALPs) approach closely enough to pulsars, they can be resonantly converted to photons, yielding dramatic electromagnetic signals. We discuss the possibility of detecting such signals from bound configurations of axions, colliding with pulsar magnetospheres. We find that all but the densest axion stars, $\textit{oscillons}$, are tidally destroyed well before resonant conversion can take place. Oscillons can be efficiently converted to photons, leading to bright, ephemeral radio flashes. Observation of the galactic bulge using existing (Very Large Array and LOFAR) and forthcoming (Square Kilometer Array) radio missions has the potential to detect such events for axion masses in the range $m_a \in \left[0.1 \ μ\text{eV}, 200 \ μ\text{eV}\right]$, even if oscillons make up a negligible fraction of dark matter.
