Description
The massive compact halo objects (MACHOs) such as primordial black holes
or dense mini-halos can gravitational lens the signal of gamma ray bursts (GRB)
and fast radio bursts (FRB). I will discuss that most GRB spectra are
inappropriate for this kind of lensing searches due to their large sizes.
However, FRB lensing, producing a characteristic interference pattern in the
frequency spectrum, can probe the MACHOs in the mass range from 10^−4 to
0.1 solar mass.
