Radio Search of Dark Matter

  • Abstract
    Dark matter is the dominant matter in the Universe but its nature is still unknown. In recent years, indirect detection search, especially using radio telescopes becomes a main stream of searching for dark matter candidates. In this talk, I will introduce three major scenarios of dark matter widely considered as the dark matter candidates: Axion-Like-Particles (ALP), Axion dark matter and WIMP (Weakly Interactive Massive Particle) and show what mechanism they can manifest and radiate the radio waves that are possibly detectable with mid-frequency radio telescopes. I will then discuss how the current radio telescopes, such as FAST, MeerKAT and SKA can search the DM candidates and put constraints on their physical parameters.

    Bio:

    Professor Yin-Zhe Ma obtained his Bachelor's degree in Physics from Nanjing University, a master's degree from the Institute of Theoretical Physics at the Chinese Academy of Sciences (supervisor: Prof. Rong-Gen Cai), and a Ph.D. degree in Astronomy from the University of Cambridge (supervisor: Prof. George Efstathiou FRS). He conducted CITA National Fellowship at the University of British Columbia Canada and a research associate at the University of Manchester, and then moved to the University of KwaZulu-Natal South Africa as a senior lecturer (2015) and then an associate professor (2018) and a full professor (2021). In 2023, he moved to Stellenbosch University as a full professor and the founding head of astrophysics division in physics department. He chairs the NAOC-UKZN Computational Astrophysics Centre and the Chinese-South African Forum of Astronomy. He was also an adjunct professor at Purple Mountain Observatory and National Astronomical Observatory China during 2017-2021.His research focuses on observational and theoretical cosmology aimed at understanding the fundamental laws of the Universe and uncovering the nature of dark energy and dark matter. He is currently a core member of the Square Kilometer Array (SKA) Science Working group, the Planck science team, Hydrogen Epoch Reionization Array (HERA), and the CMB Stage-4 experiment and LSST (Vera C. Rubin Observatory). With the Planck science team, he was awarded the 2018 “Gruber Cosmology Prize” by the IAU. He has published over 120 papers, with total citations exceeding 26000, h-index 45. He was awarded the NSFC Oversea Scholar grant and several South Africa National Research Foundation grants. He was elected to theAcademy of Science of South Africa in 2022.
