※Description:
Fast radio bursts (FRBs) are mysterious radio flashes with millisecond timescales, most of which emerge in the extragalactic Universe. Understanding FRB’s origin is one of the most important missions in astronomy. However, the poor localization capability of the current FRB survey telescopes has been hampering the identification of FRB progenitors. To overcome this problem, we will utilize unique statistical approaches to constrain the progenitor types of FRBs. The summer student will work on either (i) FRB host galaxies, (ii) the number density evolution of FRBs across cosmic time, or (iii) the machine-learning classification of FRBs. We plan to use the new CHIME baseband data with improved positional accuracy and the 2nd CHIME FRB catalog, which will include about one order of magnitude larger samples than ever.
Following successful cases of past summer school students, we plan to publish a paper based on this project. The supervisor will provide the student with a working desk in his office to maximize the research efficiency during the program.
※Required Background:
Unix/Linux experience and programming skills such as Python are recommended,
although learning them is a part of the summer student program.
Basic background in physics.
