A new ability to pinpoint sources of fast radio bursts

CHIME is great because it is so cheap. It&#x27;s parabolic cylinders lying on the ground pointing fixedly straight up. The construction and mantainence cost per meter^2 of effective aperture is the lowest it possibly can be. It&#x27;s basically a handful of large &quot;half pipe&quot; looking things next to shipping containers packed full of GPUs and power equipment. The only downside to this parabolic cylinder design is reflections down the long axis of the cylinder but that can be mitigated.<p>It&#x27;s a (nearly) filled aperture with lots of redundant baselines which allows for easier calibration and seeing through the galactic foreground. But being so (relatively) closely spaced it&#x27;s resolution is limited. Adding outriggers fixes this for when they want to get a position and I&#x27;d bet they put one at angles to the main array cylinder direction.

That&#x27;s a coincidence, Australian astronomers published a paper on a new interferometry-based system for fast radio burst detection today too:<p><a href="https:&#x2F;&#x2F;www.csiro.au&#x2F;en&#x2F;news&#x2F;All&#x2F;News&#x2F;2025&#x2F;January&#x2F;Australian-innovation-sifts-space-for-mysteries" rel="nofollow">https:&#x2F;&#x2F;www.csiro.au&#x2F;en&#x2F;news&#x2F;All&#x2F;News&#x2F;2025&#x2F;January&#x2F;Australia...</a><p><a href="https:&#x2F;&#x2F;www.cambridge.org&#x2F;core&#x2F;journals&#x2F;publications-of-the-astronomical-society-of-australia&#x2F;article&#x2F;craft-coherent-craco-upgrade-i-system-description-and-results-of-the-110ms-radio-transient-pilot-survey&#x2F;DDFC21A8ACFCAFE88561FC2856503558" rel="nofollow">https:&#x2F;&#x2F;www.cambridge.org&#x2F;core&#x2F;journals&#x2F;publications-of-the-...</a>
