Investigating the sightline of a highly scattered FRB through a filamentary structure in the local Universe
Kaitlyn Shin, Calvin Leung, Sunil Simha +31
Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it e…
