Professor Hiroyasu TAJIMA

I am investigating origins, acceleration mechanisms, and propagation of cosmic rays, and search for gamma-ray signals from dark matter by development of semiconductor sensors and integrated circuits for gamma-ray instruments such as the *Fermi* satellite and Cherenkov Telescope Array and their data analysis. I am also developing microsatellites to stimulate satellite applications.

Professor Masaki YAMASHITA

My main research interest is in particle physics and astrophysics, in the particular domain of dark matter and neutrino. I look for dark matter particles by detecting directly via elastic scattering of target nuclei in the terrestrial detector located in the deep underground laboratories. I am currently working on the XENONnT and XLZD experiment, which uses liquid xenon technology in the undergournd laboratory.

I am currently studying the variations of past cosmic ray intensities and solar activities by measuring the ¹⁴C content in tree rings and 10Be concentrations in ice cores. I am aiming to understand the occurrence features of extreme solar proton events through the investigation of ¹⁴C data over the past several tens of thousands of years. I am also interested in annual dating of ancient samples by using rapid ¹⁴C variations.

I am aiming at unveiling relation between accretion disks and relativistic jets around a black hole and radiation mechanisms of gamma-ray bursts (GRBs) using X-ray and gamma-ray satellites. I am also recently working on solar neutron observations from space using a micro-satellite.

Assistant Prof. Hiroaki MENJO

For my research, I study high-energy particle interactions of cosmic rays using an accelerator. Cosmic rays interact with interstellar gas or the Earth's atmosphere and produce numerous particles. A precise understanding of cosmic-ray interactions is important to solve the mystery of the origin of cosmic rays. I am currently measuring particles produced in high-energy interactions at the world's biggest accelerator, LHC.

Designated Assistant Prof. Masatoshi KOBAYASHI

I have been working on the direct search of dark matter, using liquid xenon detectors. Currently, the main research topic is the data analysis and hardware development for XENONnT experiment in LNGS, Italy. I am also working on the R&D project for future large scale dark matter search, DARWIN experiment.

Designated Assistant Professor Fernando Monterde-Andrade

I am interested in studying the cosmic rays variations related to extreme solar particle events. I am currently working in modelling the spectra of such extreme events and the associated production and transport of cosmogenic isotopes, as they are proxies of significant solar activity. I aim to investigate the features and frequency of extreme solar particle events in the past and apply that knowledge to understand the Sun at its present and its future.

Project Postdoc Researcher Marcelo Ismerio Moreira Leite de Oliveira

I am working on dark matter searches with liquid xenon detectors in the XENON collaboration. My research focuses on low-background analysis and rare-event detection, including searches for inelastic dark matter (iDM), with additional interest in solar and atmospheric neutrinos as both signals and backgrounds.
