摘要:

我们在1.5米的Harold L.圣佩德罗·马蒂尔山脉国家天文台的约翰逊望远镜。我们的同质$griZYJH$测光从爆发之夜延伸到三年后。我们为余辉做了一个模型。在$griZ$滤波器中有一个显著的正残差,与SN 1998 bw的行为相匹配;我们认为这是与伽马射线暴相关的超新星SN 2013 cq的光度特征。超新星的绝对星等峰值是$M_r=-18.43\pm0.11$。

英文摘要:

We observed the afterglow of GRB 130427A with the RATIR instrument on the 1.5-m Harold L. Johnson telescope of the Observatorio Astronómico Nacional on Sierra San Pedro Mártir. Our homogenous $griZYJH$ photometry extends from the night of burst to three years later. We fit a model for the afterglow. There is a significant positive residual which matches the behavior of SN 1998bw in the $griZ$ filters; we suggest that this is a photometric signature of the supernova SN 2013cq associated with the GRB. The peak absolute magnitude of the supernova is $M_r=-18.43\pm0.11$.
