WebbThrough the relationship between dispersion measures (DM) and redshifts, fast radio bursts (FRBs) are considered to be very promising cosmological probes. In this paper, we attempted to use the DM-z relationship of FRBs to study the helium abundance (YHe) in the universe. First, we used 17 current FRBs with known redshifts for our study. Due to their … WebbFast radio bursts (FRBs) are broadband, millisecond-duration bursts of radio emission visible at cosmological distances. As FRBs traverse the intergalactic medium, their …

"WebbFast radio bursts (FRBs) were discovered only in 2007. However, the number of known events and sources of repeating bursts grows very rapidly. In the near future, the number of events will be ≳104 and the number of repeaters ≳100. Presently, there is a consensus that most of the sources of FRBs might be neutron stars (NSs) with large … " - The physical mechanisms of fast radio bursts
