论文摘要
我们在1.3GHz（Meerkat）和15.5GHz（Arcminute Microkelvin Imager-大型阵列，AMI-LA）上介绍了我们的长期无线电监控活动的结果，以爆发最近发现的Neutron STAR X射线X射线X射线二元二进制二进制二进制二进制Swift Swift J1858.6-0814。在整个爆发过程中，我们观察到无线电发射与准敏感的，自吸收的喷气机一致。此外，我们在MJD 58427和58530上看到了两个耀斑。第二耀斑使我们能够分别在0.2G和5x10^37erg的磁场上放置约束，并将约束放置。我们将多频无线电数据与来自Swift-Bat的数据结合使用，将Swift J1858.6-0814放在无线电/X射线相关性上。我们发现，准简单的无线电和BAT数据使Swift J1858.6-0814似乎在环礁和Z源之间弥合了无线电/X射线平面的间隙。此外，在柔软的状态下进行了AMI-LA观察，而Swift J1858.6-0814使我们能够证明软性期间的无线电发射至少被至少四倍。
We present the results of our long term radio monitoring campaign at 1.3GHz (MeerKAT) and 15.5GHz (Arcminute Microkelvin Imager - Large Array, AMI-LA) for the outburst of the recently discovered neutron star X-ray binary Swift J1858.6-0814. Throughout the outburst, we observe radio emission consistent with a quasi-persistent, self-absorbed jet. In addition, we see two flares at MJD 58427 and 58530. The second flare allows us to place constraints on the magnetic field and minimum energy of the jet at 0.2G and 5x10^37erg, respectively. We use the multi-frequency radio data in conjunction with data from Swift-BAT to place Swift J1858.6-0814 on the radio/X-ray correlation. We find that the quasi-simultaneous radio and BAT data makes Swift J1858.6-0814 appears to bridge the gap in the radio/X-ray plane between atoll and Z sources. Furthermore, AMI-LA observations made whilst Swift J1858.6-0814 was in the soft state have allowed us to show that the radio emission during the soft state is quenched by at least a factor of four.
