Many concepts in astrophysics research can be difficult for a lay individual to understand or to comprehend their importance. One such example concept is the IceCube Neutrino Observatory, which detects high-energy neutrinos at the South Pole in Antarctica. The observatory uses information from detected neutrinos originating deep in outer space to…

Large-group (n > 8) co-located collaboration has not been adequately studied because it demands different conceptual framings than those used to study small-group collaboration, while also posing pragmatic constraints on data collection. Working within these pragmatic constraints, we use video data to devise an indicator of the current…
