Investigating an angular correlation between nearby starburst galaxies and UHECRs with the Telescope Array experiment [PDF]

open access: yesEPJ Web of Conferences, 2019
The arrival directions of cosmic rays detected by the Pierre Auger Observatory (Auger) with energies above 39 EeV were recently reported to correlate with the positions of 23 nearby starburst galaxies (SBGs): in their best-fit model, 9.7% of the cosmic ...

Design and operation of a 1500-m laser strainmeter installed at an underground site in Kamioka, Japan

open access: yesEarth, Planets and Space, 2017
A laser strainmeter with a 1500-m baseline was constructed at an underground site in Kamioka, Gifu Prefecture, Japan, and has been operating since August 2016. The laser interferometer measures the change in distance between two retroreflectors housed in

Muon g − 2 in gauge mediation without SUSY CP problem

open access: yesJournal of High Energy Physics, 2021
We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously.

On stability of fermionic superconducting current in cosmic string

open access: yesJournal of High Energy Physics, 2021
Recently, the chiral superconductivity of the cosmic string in the axion model has gathered attention. The superconductive nature can alter the standard understanding of the cosmology of the axion model.

Probing the Galactic cosmic ray flux with submillimeter and gamma ray data [PDF]

open access: yes, 2008
The study of Galactic diffuse $\gamma$ radiation combined with the knowledge of the distribution of the molecular hydrogen in the Galaxy offers a unique tool to probe the cosmic ray flux in the Galaxy.

Galactic Center Observations with CTAO LST-1 [PDF]

open access: yesEPJ Web of Conferences
Very-high-energy gamma-ray observations of the central part of the Milky Way Galaxy allow for morphological study of cosmic-ray propagation around the supermassive black hole Sgr A*. An interpretation of the diffuse gamma-ray component, which spans a few

Light Element Evolution and Cosmic Ray Energetics [PDF]

open access: yes, 1999
Using cosmic-ray energetics as a discriminator, we investigate evolutionary models of LiBeB. We employ a Monte Carlo code which incorporates the delayed mixing into the ISM both of the synthesized Fe, due to its incorporation into high velocity dust ...

The Auger@TA Project: Phase II Progress and Plans [PDF]

open access: yesEPJ Web of Conferences, 2019
The Auger@TA project is a combined effort involving members of both the Pierre Auger Observatory and the Telescope Array experiment (TA) to cross-calibrate detectors and compare results on air showers detected at one location.
