Searching for the Signature of Fast Radio Burst by Swift/XRT X-ray Afterglow Light Curve
Hsien-chieh Shen, Takanori Sakamoto, Motoko Serino +1
A new type of cosmological transient, dubbed fast radio bursts (FRBs), was recently discovered. The source of FRBs is still unknown. One possible scenario of an FRB is the collapse…
