摘要:
Fast Radio Bursts are millisecond time scale radio pulses detected across cosmological distances, the high-energy astrophysical process of FRBs is yet to be understood. The temporal properties of FRBs such as dispersion, scattering and pulse profile reveals the effects of propagation through large columns of plasma in our universe. The pulse profiles of FRBs also reveal import physical processes of the progenitor and evidence of repetition. In this talk I display the temporal broadening of 32 FRB detections with ASKAP to discuss the distribution of scattering and the location of these plasma screens. I then focus on the microstructure pulse profile studies of FRB 181112 at sub microsecond resolution to discuss how both anomalous and empirical temporal broadening of FRBs could be useful probes of baryonic matter in our universe.
