Fast Radio Bursts (FRBs) are enigmatic sources that could be caused by a variety of mechanisms, ranging from magnetars to merging white dwarfs. In this project, we use the ASKAP sample of FRBs and their host galaxies to characterize FRB environments, and connect to simulations over cosmic time. We will improve our understanding of the sample of FRB host galaxies, and how repeaters/non-repeaters vary with host type. We will compare this sample with simulations of galaxy assembly at different redshifts. This project also has the option to look into simulations of star clusters to search for alternate pathways of FRB origins such as neutron stars.
Aim
The aim of this project is to combine our understanding of galaxy assembly over cosmic time and relate it to the observed properties of FRB host galaxies. This will involve both the ASKAP sample, and comparing it to state-of-the-art simulations. It will enable such questions as how does the distribution of host galaxies change over redshift, and how does this match to our understanding of galaxy evolution? And can alternative explanations for FRB origins match to models of neutron star evolution in dynamic environments?
Objectives
The objectives of this project will be to perform a systematic study of FRBs and their host galaxies, with the goal of aligning theory and observation. This will involve analysis of ASKAP FRBs and their known hosts, as well as working with the output of simulations as a comparison point. This will enable a detailed study of the origins of FRBs, and understanding how their diverse environments could have led to such energetic signals.
Significance
Since their discovery in 2013, FRBs have been some of the most puzzling signals detected. Their origins may hold the key to understanding their nature. By performing a systematic study of their hosts over cosmic time, we may be able to better unravel their mysterious origins.
