UTokyoNY Event by ICRR

【Adding Event Report】Symposium “Exploring the Universe with Multi-Messengers”



Institute for Cosmic Ray Research, The University of Tokyo explores the frontier of the cosmic ray physics, astrophysics and elementary particle physics based on the coordinated observation and interpretation of "multi- messenger" signals such as cosmic rays, gamma rays, neutrinos, gravitational waves, and dark matter. Researchers from ICRR and other research institutes and universities in the world get together in this symposium to discuss how to tackle the mystery of the universe through their research programs.

He specializes in high energy gamma ray astronomy, cosmic ray physics and astroparticle physics and serves as PI of LST which is the part of CTA being under construction in LaPalma, Canary Islands, Spain. LST-1, prototype of LST was inaugurated in October 2018 and selected "21st Century Technology Awards 2019" and "European Technology Awards 2021".

Reshmi Mukherjee
Helen Goodhart Altschul Professor of Barnard College, Columbia University

Reshmi Mukherjee is also the Vice Provost of Academic Centers and Research at Barnard College. Her research interests are in high-energy astrophysics and astroparticle physics. She uses ground-based atmospheric Cherenkov telescopes at the VERITAS Observatory located in southern Arizona to study galactic and extragalactic high-energy gamma-ray sources. Her area of expertise is active galaxies, thought to be powered by supermassive black holes at their centers. She was formerly Spokesperson of VERITAS. She is currently also a member of CTA.

Hiroyuki Sagawa
Vice Director, Professor of Institute for Cosmic Ray Research, UTokyo

Hiroyuki Sagawa devotes himself to lead and was the former co-spokesperson of the Telescope Array(TA) experiment in Utah for searching origins of ultra-high energy cosmic rays around 1020eV (Former co-spokesperson), and is involved in the construction of TAx4 which quadruple the TA effective area. The project team obtained evidence for a cluster of events (hotspot) in the direction of Ursa Major.

Glennys Farrar
Silver Professor and Collegiate Professor of Physics at New York University

Glennys Farrar specializes in particle physics, cosmology and the study of dark matter. She earned her PhD from Princeton in 1971, becoming the first woman to receive a physics PhD from Princeton University. At NYU, she chaired the physics department and founded the Center for Cosmology and Particle Physics. She is a recent Chair of the American Physical Society's Division of Astrophysics, and a member of the Snowmass Steering Group. She is also a member of Auger which detects ultra-high energy cosmic rays in the southern hemisphere and expected to tell us her perspective on uncovering the origins of UHECRs with TA, Auger and IceCube.

Masato Takita
Professor of Institute for Cosmic Ray Research, UTokyo

Masato Takita is PI of Tibet ASγ experiment which aims to observe high energy cosmic rays at Yangbajing in Tibet, China. After installation of underground muon detectors, 100 TeV gamma rays were successfully detected. He was awarded 67th Nishina Memorial Prize in 2021 for “establishment of the sub-PeV gamma ray astronomy and elucidation of the origin of galactic cosmic rays”.

Peter K. Fritschel
Principal Investigator of MIT Kavli Institute for Astrophysics and Space Research

Peter K. Fritschel is currently Chief Detector Scientist for LIGO - the Laser Interferometric Gravitational-wave Observatory. His research has focused on the design and development of ground-based gravitational-wave detectors, using extraordinarily sensitive, multi-kilometer baseline interferometers. He is a recipient of the 2016 Special Breakthrough Prize in Fundamental Physics awarded to the LIGO Collaboration and the 2022 Richard A. Isaacson Award in Gravitational-Wave Science.

Peter Shawhan
Professor at University of Maryland

Peter Shawhan is a Professor at University of Maryland, Department of Physics. His primary research for the past 20 years has been direct detection of gravitational waves with the LIGO and Virgo detectors, and he has held numerous leadership positions within the LIGO Scientific Collaboration. He was instrumental in establishing and nurturing a program of sharing prompt information about gravitational-wave event candidates with astronomers to allow them to look for corresponding signals in their instruments. That groundwork enabled a remarkably rich campaign of astronomical follow-up observations and study, spanning the whole electromagnetic spectrum, when LIGO and Virgo detected the first binary neutron merger event, in August 2017. As a LIGO contributor, he is a recipient of the 2016 Special Breakthrough Prize in Fundamental Physics awarded to the LIGO Collaboration. He is now serving as President of the IAU Commission on Gravitational Wave Astrophysics. He has been named a University of Maryland Distinguished Scholar-Teacher since 2021.

Cherenkov Telescope Array (CTA)

During the past few years, Very High Energy (VHE) gamma ray astronomy has made spectacular progress and has established itself as a vital branch of astrophysics. To advance this field even further, Cherenkov Telescope Array (CTA), the next generation VHE gamma ray observatory, was proposed in the framework of a worldwide, international collaboration.

Telescope Array Experiment (TA)

The Telescope Array (TA) was built in Utah, USA to study the origin and nature of Ultra-High Energy Cosmic Rays (UHECRs). The project has been operated by the international collaboration of researchers from Japan, USA, Korea, Russia, Belgium and Czechia. In 2019, construction of the TA extension (TAx4), which will quadruple the TA effective area started.

Tibet ASγ Experiment

In collaboration with China, an air shower observation array was built at Yangbajing in Tibet, China to observe high-energy cosmic rays. Underground muon detectors added to the site worked successfully in detecting gamma rays over 100 TeV which revealed the existence of yet-unknown cosmic ray accelerator (PeVatron) in our galaxy.
