Fast Radio Bursts:
Fast Radio Bursts (FRBs) are mysterious radio bursts discovered in 2007. Their origin remains unknown, even though recently one of them (the only that is observed to emit repeating bursts, dubbed FRB 121102) was localized to a star forming galaxy at z=0.193. This established a cosmological origin of at least this one event. It is widely believed that other FRBs are also from cosmological distances, even though whether there exists a sub-category of non-repeating ones is not clear.
Together with my collaborators, I am actively working in this emerging new field.
Recently, together with Duncan Lorimer (discoverer of the first FRB), Sarah Burke-Spolaor from West Virginia University and Edo Berger from Harvard University, I have organized the first major meeting in FRBs, i.e. the 2017 Winter FRB Conference at Aspen Center for Physics. The conference hosted about 80 scientists over the world to discuss the nature of these mysterious bursts. The event was reported in the Nature magazine and Scientific American.
