The cosmic enigma known as fast radio bursts are one of the major puzzles in contemporary astrophysics. These bursts are powerful pulses of radio emission that releases as much energy in a millisecond as the Sun
puts out in a year. Their exact origin and emission mechanisms, however, remains unclear. This project has helped shed light on the origins of fast radio bursts by studying their host galaxy environments.
Uncovering the origin of fast radio bursts will not only have immense impact on our understanding of these extreme astrophysical processes. It will also benefit the study of compact objects in general, how these exotic objects are formed, and their place in the overall scheme of galaxy evolution.
· Information on how the results will be applied
With the better understanding of the origin of fast radio bursts delivered by this project, it will also become possible to fully utilize their powerful signals as unique tracers of all the baryons that permeates the "cosmic web" of intergalactic gas, which is otherwise invisible due to its hot, diffuse state. Quantifying the presence and distribution of this diffuse gas will further allow us to independently infer the expansion rate of the Universe.
· A list of the project’s outputs
In addition to the two published papers, the processed data, results and software used and developed for this project has been made publicly available on a dedicated GitHub repository (https://github. com/FRBs). As a front-end to this repository, I am also currently running the FRB host database (https://frbhosts.org), providing an up-to-date overview of all the derived galaxy properties of the currently known FRB hosts.
