Losing Arecibo was, as I understand it, a big blow to the NANOGrav experiment, which is looking for very low frequency gravitational waves by measuring pulsar timing variations[1]. Albeit having limited field of view the Arecibo Telescope was very sensitive[2], and so could see pulsars that the other telescopes they used could not. And the longer they could collect data from a set of pulsars the lower frequency waves they could probe.
