论文摘要

在核心溢出的超新星(SN)期间,可以通过Primakoff工艺产生轴突状颗粒(ALP),然后在银河系的磁场中转换为$γ$射线。我们找不到与费米大面积望远镜(LAT)观察到这种$γ$射线的证据。 SN爆炸时间是从光学光曲线中估算的,我们发现在核心崩溃时LAT观察到的LAT至少一个SN的概率约为$ 90%。在假设至少一个Sn包含在LAT视图中的假设下,我们排除了photon-alp耦合$ \ gtrsim 2.6 \ gtrsim 2.6 \ times10^{ - 11} $ gev $^{ - 1} $ for alp smases $ m_a \ m_a \ sim sim 3 \ lisssim 3 \ linssim 3 \ times 10^{ - 10^{ - 10^$ ev,以前7 $ \ sim 7 $ \ sim 7 $ \ sims 7 $ \ 7 $ \ sims。

During a core-collapse supernova (SN), axionlike particles (ALPs) could be produced through the Primakoff process and subsequently convert into $γ$ rays in the magnetic field of the Milky Way. We do not find evidence for such a $γ$-ray burst in observations of extragalactic SNe with the Fermi Large Area Telescope (LAT). The SN explosion times are estimated from optical light curves and we find a probability of about $\sim$90% that the LAT observed at least one SN at the time of the core collapse. Under the assumption that at least one SN was contained within the LAT field of view, we exclude photon-ALP couplings $\gtrsim 2.6\times10^{-11}$GeV$^{-1}$ for ALP masses $m_a \lesssim 3\times 10^{-10}$ eV, within a factor of $\sim 5$ of previous limits from SN1987A.
