A multimessenger approach to astroparticle physics

My name is Marco Muzio, I am currently a NSF MPS-Ascend Postdoctoral Fellow at Pennsylvania State University. My research focuses on understanding the origins cosmic messengers at the energy frontier. I aim to elucidate the astrophysical origins of ultrahigh energy particles and to leverage them to probe particle physics beyond the Standard Model. To do this my research takes a multimessenger approach, combining data from cosmic rays, neutrinos, and gamma-rays to obtain a more complete picture of their origins. This approach has led to important new insights into extreme astrophysical accelerators and revealed new connections (and opportunities) between these messengers. In practice my research takes two complementary approaches: developing phenomenological models of multimessenger data at ultrahigh energies and search for ultrahigh energy neutrinos with cutting-edge experimental methods.
