Mitigating radio frequency interference in CHIME/FRB real-time intensity data

Understand

Extragalactic fast radio bursts (FRBs) are a new class of astrophysical transients with unknown origins that have become a main focus of radio observatories worldwide.

• FRBs are highly energetic ($\sim 10^{36}$-$10^{42}$ ergs) flashes that last for about a millisecond.
• Thanks to its broad bandwidth (400-800 MHz), large field of view ($\sim$200 sq.
• deg.), and massive data rate (1500 TB of coherently beamformed data per day), the Canadian Hydrogen Intensity Mapping Experiment / Fast Radio Burst (CHIME/FRB) project has increased the total number of discovered FRBs by over a factor 10 in 3 years of operation.
