论文摘要
我们介绍了迄今为止，最大，最深的后期无线电和毫米测量，迄今为止，超浮肿的超新星（SLSNE）和长持续时间伽马射线爆发（LGRB）搜索相关的非热同步器发射。使用Karl G. Jansky非常大的阵列（VLA）和Atacama大毫米/亚毫米阵列（ALMA），我们在$ \ sim 1-19 $ yr yr yr yr yr yr post -y y yr post -y yr post -y yr seplosion的时间表上观察到43个来源。除了6 GHz检测PTF10HGI（Eftekhari etal。2019），以及在SLSN PTF12DAM的位置附近检测到6 GHz发射的位置，我们也没有检测到任何来源的无线电/MM发射（Eftekhari etal。2019）。我们使用数据对中央发动机排放构成限制，这是由于磁性风星云和离轴相对论喷气机而引起的。我们还探索了SN射流中的非相关性发射，并在宿主星系中对遮盖的恒星形成放置约束。此外，我们使用VLA分阶段阵列观测值对一些来源进行快速无线电爆发（FRB）进行了搜索。在每个事件的源源约40分钟内，未检测到FRB的限额为$ 16 $ MJY（$7σ$; 10毫秒持续时间）。与理论模型的比较表明，持续的无线电监视可能会导致检测到$ \ gtrsim {\ rm十年} $的时间标准的持续无线电发射。
We present the largest and deepest late-time radio and millimeter survey to date of superluminous supernovae (SLSNe) and long duration gamma-ray bursts (LGRBs) to search for associated non-thermal synchrotron emission. Using the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), we observed 43 sources at 6 and 100 GHz on a timescale of $\sim 1 - 19$ yr post-explosion. We do not detect radio/mm emission from any of the sources, with the exception of a 6 GHz detection of PTF10hgi (Eftekhari et al. 2019), as well as the detection of 6 GHz emission near the location of the SLSN PTF12dam, which we associate with its host galaxy. We use our data to place constraints on central engine emission due to magnetar wind nebulae and off-axis relativistic jets. We also explore non-relativistic emission from the SN ejecta, and place constraints on obscured star formation in the host galaxies. In addition, we conduct a search for fast radio bursts (FRBs) from some of the sources using VLA Phased-Array observations; no FRBs are detected to a limit of $16$ mJy ($7σ$; 10 ms duration) in about 40 min on source per event. A comparison to theoretical models suggests that continued radio monitoring may lead to detections of persistent radio emission on timescales of $\gtrsim {\rm decade}$.
