About this Event
View map Free EventFast radio bursts (FRBs) are possibly the biggest enigma in astronomy
today. FRBs are brief (~ms), bright (often many Jy) flashes at ~GHz
frequencies. While they are now known to be extragalactic, little
else is known about their origins. One of the challenges in studying
FRBs has been localizing them well enough to tie them to host
galaxies, and hence get redshifts. The Hydrogen Intensity and
Real-time Analysis eXperiment (HIRAX) is a planned array of 1024 6m
diameter radio telescopes that is slated to begin construction in the
South African Karoo desert later this year. One of its main goals is
to study FRBs, including localizing their host galaxies. The Canadian
Hydrogen Observatory and Radio-transient Detector (CHORD) is a
proposed follow-on to CHIME/HIRAX, that will also search for and
localize FRBs. With localizations of large numbers of FRBs from
instruments like HIRAX and CHORD, FRBs hold great promise as probes of
cosmology and fundamental phsyics, as they provide an extraordinarily
precise measurement of the (redshift-weighted) line-of-sight integral
of the electron column density. I will present how we plan to study
FRBs with HIRAX and CHORD, including some of what we hope to learn
about the universe
