Title: A High-Resolution View of Fast Radio Burst Host EnvironmentsAuthors: Alexandra G. Mannings, Wen-fai Fong, Sunil Simha, J. Xavier Prochaska, Marc Rafelski, Charles D. Kilpatrick, Nicolas Tejos, Kasper E. Heintz, Shivani Bhandari, Cherie K. Day, Adam T. Deller, Stuart D. Ryder, Ryan M. Shannon, Shriharsh P. TendulkarFirst Author’s Institution: Department of Astronomy and Astrophysics, University of California, Santa Cruz, CA 95064, USAStatus: Submitted to APJ [closed access] First discovered in 2007, fast radio bursts (FRBs) have been the talk of the town for the last few years. As their name suggests, they emit very fast (millisecond) long bursts of radiation at radio frequencies. Due to their very high dispersion measures (DMs), we know that FRBs are typically located in galaxies outside of the Milky Way, although the first galactic FRB was detected in March 2020. While the majority of FRBs are one-off events, some FRBs repeat, and two even repeat periodically! FRBs have only been detected using radio telescopes, but there are many ongoing efforts to observe them in other wavelengths. However, even with the huge effort to study them over the last few years, we still have much to learn about these objects. In particular, while hundreds of FRBs ...
