First results on the search for the Galactic Center Excess in the sub-GeV band with the emulsion telescope in GRAINE 2023

Yuya Nakamura, Shigeki Aoki, Takashi Azuma +34

(Please check the paper for full abstract.) The Galactic Center Excess (GCE) is an unexplained excess of gamma-ray emission from the Galactic Center. The GRAINE experiment aims to…

First overnight balloon flight of the GRAINE 2023 emulsion gamma-ray telescope enabled by a large-scale pressure-vessel gondola

Hiroki Rokujo, Shigeki Aoki, Takashi Azuma +34

The Gamma-Ray Astro Imager with Nuclear Emulsion (GRAINE) project conducts precision observations of sub-GeV--GeV cosmic gamma rays using a balloon-borne nuclear-emulsion telescope…

Measurement of reconstructed final-state kinematics in charged-current interactions on water using the J-PARC beam and NINJA emulsion detector

NINJA Collaboration, A. Kasumi, S. Han +50

We present a study of charged-particle multiplicities and the kinematic distributions of muons, protons, and charged pions in a flux-integrated sample of charged-current inclusive…

New high-precision measurement system for electron-positron pairs from sub-GeV/GeV gamma-rays in the emulsion telescope

Yuya Nakamura, Shigeki Aoki, Tomohiro Hayakawa +27

The GRAINE project observes cosmic gamma-rays, using a balloon-borne emulsion-film-based telescope in the sub-GeV/GeV energy band. We reported in our previous balloon experiment in…

First demonstration of gamma-ray imaging using balloon-borne emulsion telescope

Hiroki Rokujo, Shigeki Aoki, Kaname Hamada +30

We promote the precise gamma-ray observation project Gamma-Ray Astro-Imager with Nuclear Emulsion (GRAINE), which uses balloon-borne emulsion gamma-ray telescopes. The emulsion tel…
