相对论性轴子从瞬变源（如轴子星星爆炸）的发射，可以导致可观测的特征。我们发现，在实验室实验中，如ABRACADABRA，DMRadio和SHAFT，可以在轴子质量10− 15 eV <$m <$10 − 7 eV的范围内检测到坍缩轴子星的轴子爆发。轴子爆发的检测可以提供新的见解的基本轴子潜力，这是具有挑战性的探测，否则。在遥远的过去，一系列的爆发会产生一个与通常的冷轴子DM不同的弥散轴子背景。与其他特征的重合将为多信使天文学提供一个新的窗口。
Emission of relativistic axions from transient sources, such as axion star explosions, can lead to observable signatures. We show that axion bursts from collapsing axion stars can be detectable over the wide range of axion masses 10− 15 eV≲ m≲ 10− 7 eV in laboratory experiments, such as ABRACADABRA, DMRadio and SHAFT. The detection of axion bursts could provide new insights into the fundamental axion potential, which is challenging to probe otherwise. An ensemble of bursts in the distant past would give rise to a diffuse axion background distinct from the usual cold axion DM. Coincidence with other signatures would provide a new window into multi-messenger astronomy.
