Cool Worlds Podcast

In this week's episode, David is joined by Chiara Mingarelli. Prof Mingarelli is currently moving from the University of Connecticut to Yale University and is theorist working on the so-called background gravitational wave signal. Predicted for decades but incredibly elusive, we are on the cusp of detecting this signal for the first time. Learn all about what this signal is and what it means for astronomy in today's episode.

Leading cosmologist Wendy Freedman discusses the crisis in cosmology, advancements in cosmology from glass plates to CCDs, historical observations of dark matter, challenges of science communication in cosmology, unknown systematics in cosmological measurements, tension between measurements of cosmic background and cepheids, and importance of independent checks in cosmology.

In our inaugural episode, David is joined by Rebecca Charbonneau. Dr Charbonneau holds a PhD in the History of Science from Cambridge University, and served as the Historian-in-Residence at the Harvard-Smithsonian Center for Astrophysics from 2020-2022. She is currently a Janksy Fellow at the National Radio Astronomy Observatory (NRAO) and working on an upcoming book exploring the history of SETI - the Search for ExtraTerrestrial Intelligence.   To support this podcast and our research lab, head to www.coolworldslab.com/support
