9 Aug 2019 | | Abstract: | We report on the discovery of eight repeating Fast Radio Burst (FRB) sources
found using the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
telescope. These sources span a dispersion measure (DM) range of 103.5 to
1281~pc~cm$^{-3}$. For all sources, we provide sky coordinates precise to
several arcminutes. One repeater, FRB 180916.J0158+65, has a very low DM excess
over the inferred Galactic maximum, and a Faraday rotation measure $-114.6 pm
0.6$~rad~m$^{-2}$, much lower than that of the only other repeater for which
this quantity has been measured, FRB 121102. Another of our sources, FRB
181030.J1054+73, has the lowest yet known DM for a repeater,
103.5~pc~cm$^{-3}$, and will be an interesting target for multi-wavelength
follow-up once localized. The DM distribution of these repeaters is
statistically indistinguishable from that of the first 12 reported CHIME/FRB
sources that have thus far not repeated. On the other hand we find evidence
that repeater bursts are on average wider than those of CHIME/FRB bursts that
have not repeated, suggesting different emission mechanisms. Many, but not all
of our repeater events show complex morphologies with downward frequency drifts
reminiscent of the first two discovered repeating FRBs. These repeating FRBs
will enable interferometric localizations and subsequent host galaxy
identifications that will shed new light on the origin and nature of FRBs. | | Source: | arXiv, 1908.3507 | | Services: | Forum | Review | PDF | Favorites | |
