Program


1pm - 1:50pm

Lecture 1

The 100-year old mystery: What are Ultra High Energy Gamma Rays!

Speaker: Kazumasa Kawada (ICRR Associate Professor)

Deep in the desert of Utah of America lies a gigantic cosmic ray telescope in an area as big as the largest lake in Japan, Lake Biwa. This is the Telescope Array Experiment, a project built to observe the rare ultra-high-energy particles that fly in from space. Their energy is 100,000 to 1 million times higher than the highest energy particles humans can create today using particle accelerators. Where and how are these special particles born in the universe and how do they come to Earth? Do they originate in starburst galaxies, active galaxies, galaxy clusters, gamma-ray bursts, or other intense astronomical phenomena? Does it originate from dark matter or unknown subatomic particles with large masses? This talk will explain the mysteries of these special particles coming from the universe.


1:50pm - 2:40pm

Lecture 2

Is Dark Matter Really Dark?

Speaker: Satoshi Shirai (Kavli IPMU Associate Professor)

Dark matter is an unexplained entity that is believed to make up the majority of matter density in the Universe. Many times, observational data has strongly suggested the existence of dark matter, so much that you may even say that we have already "discovered" it. However, no one has been able to detect it directly, and its true nature remains a mystery. Or maybe not. Recent research has steadily advanced our understanding of the physical properties dark matter would likely possess. One new approach based on quantum gravity theory has been the talk of the community, and it could help us understand dark matter. In this talk, I will introduce the latest theoretical and experimental progress to find dark matter.


3pm - 4pm

Researcher cross talk, Q&A time with the audience
