SUMMARY:FRB science results from CHIME\, Physics Department Colloquium
 \, Kendrick Smith\, Perimeter Institute for Theoretical Physics
DESCRIPTION:Fast radio bursts (FRBs) are a recently discovered\, poorl
 y understood class of transient event\, and understanding their origin
  has become a central problem in astrophysics. I will present FRB scie
 nce results from CHIME\, a new interferometric telescope at radio freq
 uencies 400-800 MHz. Since 2018\, CHIME has found ~20 times more FRBs 
 than all other telescopes combined\, including ~60 new repeating FRBs\
 , the first repeating FRB with periodic activity\, an FRB pulse in our
  own galaxy from a known magnetar\, and millisecond periodicity in FRB
  sub-pulses. These results were made possible by new algorithms which 
 can be used to build radio telescopes orders of magnitude more powerfu
 l than CHIME. Looking to the future\, I'll talk about two projects in 
 progress: outrigger telescopes for CHIME\, and CHORD\, a new telescope
  with ~10 times the CHIME mapping speed.
