This presentation introduces three recent peer-reviewed papers related to the Tibet ASγ experiment published in 2025–2026. The first presents a study of the ultra-high-energy γ-ray halo surrounding the Geminga pulsar, providing new constraints on the magnetohydrodynamic turbulence around the source. The second demonstrates the experimental verification of a convolutional neural network...
Cherenkov Telescope Array Observatory (CTAO) is the next-generation very-high-energy gamma-ray observatory. Our group has been contributing to the commissioning of the telescopes since years. In this presentation, we report activities of our group and the status of the CTAO commissioning and construction.
In this sub-session, we will have flash talks on their own topics by young researchers. If you want to discuss with them, please feel free to contact them during the coffee break!

The XENONnT experiment is one of the world's most sensitive direct dark matter search experiments, employing a dual-phase liquid xenon time projection chamber to search for rare interactions between dark matter particles and xenon nuclei.
In this talk, I will introduce the scientific motivation, detector design, detection principle, and recent physics results of the XENONnT experiment
JWST observations of high-redshift galaxies have greatly advanced our understanding of cosmic reionization. Since reionization affects the CMB, I will present our recent results on constraining cosmological parameters using these galaxy observations.
Using JWST/NIRSpec medium-resolution spectra of UV-bright
galaxies at z=7.2-10.6, we investigate interstellar absorption lines to
probe the physical properties of mostly neutral gas and the early
chemical enrichment of galaxies during the epoch of reionization.
We will present a statistical rethinking of the phenomenon that the AGN in the high-z universe tends to have overmassive black holes. The result will be revisited in the aspect of both more stable statistical index and more sources.
KAGRA is a 3 km cryogenic, underground laser interferometric
gravitational-wave detector in Kamioka, Japan, and a member of the
international LIGO–Virgo–KAGRA network. This talk reviews KAGRA's
performance and contribution during the fourth observing run (O4).
