Synopsis

The CHIME telescope, originally planned for Hydrogen intensity mapping, has two instruments sensitive to rapidly varying sources: a pulsar backend which processes tracking beams produced by the correlator, and a Fast Radio Burst (FRB) detector searching for these still-mysterious millisecond signals.  I'll present some results from both instruments, including the many things CHIME has already taught us about FRBs, and the integration of the Pulsar instrument data into the NANOGrav gravitational-wave background search program.
