Bio

Yousuke Utsumi works on integration and testing for the Large Synoptic Survey Telescope (LSST) camera. The LSST camera is the next generation US's astronomical camera for mapping out the deep universe. He has been working on many kinds of astronomical topics through various instrumentation projects, especially focusing on wide field imaging. Developing the widest astronomical camera, Hyper Suprime-Cam (HSC) of the Subaru telescope operated by National Astronomical Observatory of Japan, was his first professional experience. He was in charge of developing control software and conducting the camera commissioning. He also led a project to build a new astronomical observatory in Tibet with a 50cm telescope (Hiroshima University Operated Tibet Optical Robotic Imager; HinOTORI) under a collaboration with National Astronomical Observatories of China. He made its optical design, integration and verification of the whole system and investigation of logistics between Japan and China. He also took an important role to make negotiation with both governments. His scientific interest started from investigating activity of meteor storms by developing a forward scattering radar, but now expanded to investigate Cosmology through weak lensing technique, to explore distant galaxies, and to find new types of astronomical transients associated with gravitational wave or high energy neutrino.

He holds a PhD in Science from the Graduate University for Advanced Studies in Japan. His name in Japanese Kanji Character: 内海 洋輔

    Abstract

    Previous detections of individual astrophysical sources of neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neutrinos remain unidentified. On 22 September 2017, we detected a high-energy neutrino, IceCube-170922A, with an energy of ~290 tera-electron volts. Its arrival direction was consistent with the location of a known γ-ray blazar, TXS 0506+056, observed to be in a flaring state. An extensive multiwavelength campaign followed, ranging from radio frequencies to γ-rays. These observations characterize the variability and energetics of the blazar and include the detection of TXS 0506+056 in very-high-energy γ-rays. This observation of a neutrino in spatial coincidence with a γ-ray-emitting blazar during an active phase suggests that blazars may be a source of high-energy neutrinos.
