Dark matter consists of about one quarter of the energy density in the present-day Universe and dominates the kinematic of stellar motions inside galaxies. However, physicists have no clue regarding the nature of dark matter, and searching for evidence of interaction between dark matter and the known particles has been one of the Holy Grails in modern physics. Dr. Yen-Hsun Lin, a Postdoctoral Fellow, and Dr. Meng-Ru Wu, Associate Research Fellow at the Institute of Physics, Academia Sinica, have revealed the existence of the diffuse boosted dark matter (DBDM) driven by all past supernova explosions that happened in the Universe. The study predicts that by considering the DBDM with the upcoming neutrino experiment Hyper-Kamiokande, it can probe the previously unexplored parameter space regarding the interaction cross sections of DM with electron and neutrino. This work also highlights a new avenue of utilizing our understanding of astrophysical transients to probe the fundamental particle physics. The research has been published on September 13, 2024 in Physical Review Letters.
