Abstract: The discovery of high-energy cosmic neutrinos opened a new window of astroparticle physics. Revealing the sources is also relevant for solving the long-standing puzzle about the origin of cosmic rays. I will discuss theoretical implications of the latest results on high-energy neutrino observations, and demonstrate the power of multi-messenger approaches. In particular, I will highlight our recent developments about astrophysical neutrino emission from extragalactic gamma-ray dark sources and the Galactic plane. Bio: Kohta Murase is a professor at Pennsylvania State University, holding joint appointments in the Departments of Physics and Astronomy & Astrophysics. He is also an adjunct faculty member at Yukawa Institute for Theoretical Physics at Kyoto University. Professor Murase's research interests lie in theoretical particle astrophysics and cosmology, focusing on high-energy phenomena involving neutrinos, gamma rays, cosmic rays, gravitational waves, and dark matter. He also explores high-energy astrophysical events related to stellar explosions, black holes, and neutron stars. Murase’s awards and honors include 34th Nishinomiya-Yukawa memorial Prize in 2019, an Alfred P. Sloan Research Fellowship in physics in 2017, the 2015 Young Scientist Award of the Physical Society of Japan, awarded jointly with the 2015 Incentive Award of Cosmic Ray Physics from the Cosmic Ray Researchers Congress of Japan, and the 2014 Young Scientist Award of the Astronomical Society of Japan. Before joining the faculty at Penn State, Murase was a member and Hubble Fellow at the Institute for Advanced Study in Princeton from 2012 to 2015. He was a Japan Society for the Promotion of Science (JSPS) fellow, Center for Cosmology and Astroparticle Physics (CCAPP) Senior Fellow at the Ohio State University from 2010 to 2012. He earned a doctoral degree in physics in 2010 and a master's degree in physics in 2007 at Kyoto University, and a bachelor's degree in physics at the University of Tokyo in 2005.
