Multiband Detection of Repeating FRB 20180916B

Understand

We present a multiband study of FRB 20180916B, a repeating source with a 16.3 day periodicity.

• We report the detection of 4, 1 and 7 bursts from observations spanning 3 days using upgraded Giant Metrewave Radio Telescope (300-500 MHz), Canadian Hydrogen Intensity Mapping Experiment (400-800 MHz) and Green Bank Telescope (600-1000 MHz), respectively.
• We report the first-ever detection of the source in the 800-1000 MHz range along with one of the widest instantaneous bandwidth detection (200 MHz) at lower frequencies.
• We identify 30 $\mu$s wide structures in one of the bursts at 800 MHz, making it the lowest frequency detection of such structures for this FRB thus far.
