Webb has measured the distance to the most distant fast radio burst seen to date, and CIERAβs Wen-fai Fong and her former student Alexa Gordon are co-authors on the paper published in Science.
The burst, first detected by the MeerKAT telescope, had no visible host galaxy in ground-based images. Northwesternβs special access to the MMT telescope in Arizona produced a deep image at its location that found no galaxy there, which helped pave the way for a successful JWST proposal. The team also helped interpret the Webb data.
βNormally when observing youβre excited to detect something, but in this case, not seeing anything in our MMT image was actually more exciting as that hinted that this FRB was much farther away. And indeed, it took the power of JWST to figure out just how distant this FRB truly was,β said Alexa Gordon, Brinson Prize Postdoctoral Fellow at Caltech.
Congratulations to the whole team!
First discovered in 2007, fast radio bursts are enigmatic, millisecond-long flashes of radio emission from the distant universe. Their origin remains
