Title: A bright, high rotation-measure FRB that skewers the M33 haloAuthors: Liam Connor, Joeri van Leeuwen, et. al.First Author’s Institution: Anton Pannekoek Institute, University of Amsterdam, Amsterdam, The NetherlandsStatus: Submitted to MNRAS, open access on arXiv Fast radio bursts (FRBs) are one of the hottest topics in astronomy right now. First discovered by Dr. Duncan Lorimer in 2007, these intense millisecond-long bursts of radio emission have continued to captivate scientists across the planet because they keep defying our expectations with discoveries like the repeater. Now, with the discovery of an interesting property of a new FRB just outside a major galaxy, we may be getting one step closer to finally solving one of the many puzzles of FRBs.
More Questions Than AnswersOur questions about FRBs seem to fall into two categories: What causes the bursts? And how can they be put to use? Each time the community moves toward an answer on one of these questions, a new discovery throws a wrench in it. For example, astronomers thought FRBs were single events but a discovery in 2016 showed that they can actually repeat. This opens new questions, like whether the repeaters and non-repeaters come from the same mechanism. In another ...
