Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

Comparative Testing of Subgrid Models for Fast Neutrino Flavor Conversions in Core-collapse Supernova Simulations

Ryuichiro Akaho, Hiroki Nagakura, Shoichi Yamada

We investigate key methodologies of Bhatnagar-Gross-Krook subgrid modeling for neutrino fast flavor conversions (FFC) in core-collapse supernova based on spherically symmetric Bolt…

Precision spectral measurements of Chromium and Titanium from 10 to 250 GeV and sub-Iron to Iron ratio with the Calorimetric Electron Telescope on the ISS

O. Adriani, Y. Akaike, K. Asano +77

The Calorimetric Electron Telescope (CALET), in operation on the International Space Station since 2015, collected a large sample of cosmic-ray (CR) iron and sub-iron events over a…

Asymmetric emissions of neutrinos in the cooling of rotating proto-neutron stars

Laura Barrio, Kotaro Fujisawa, Ryuichiro Akaho +2

We evaluate global asymmetry in the luminosities of neutrinos emitted from rapidly-rotating proto-neutron stars (PNS's). We build axisymmetric models of PNS's in mechanical equilib…

Asymptotic states of fast neutrino-flavor conversions in the three-flavor framework

Jiabao Liu, Hiroki Nagakura, Masamichi Zaizen +2

There has been growing evidence that mu and tau neutrinos are noticeably different due to the emergence of muons in core-collapse supernovae (CCSNe) and binary neutron star mergers…

Detection of RS Oph with LST-1 and modelling of its HE/VHE gamma-ray emission

CTA-LST Project, :, K. Abe +316

The recurrent nova RS Ophiuchi (RS Oph) underwent a thermonuclear eruption in August 2021. In this event, RS Oph was detected by the High Energy Stereoscopic System (H.E.S.S.), the…
