Proton Acceleration by Collisionless Shocks in Supermassive Black Hole Coronae: Implications for High-Energy Neutrinos
Minh Nhat Ly, Yoshiyuki Inoue, Yasuhiko Sentoku +1
Recent observations by the IceCube Neutrino Observatory have revealed a significant excess of high-energy neutrinos from nearby Seyfert galaxies, such as NGC~1068, without a corres…
XRISM Time-resolved Fe K Spectroscopy of NGC 4395: Time-variable Inner-disk Emission
Taiki Kawamuro, Satoshi Yamada, Hirofumi Noda +3
We report the first XRISM observation of the low-mass AGN in the nearby dwarf galaxy NGC 4395 (), complemented by a simultaneous NuSTAR observation…
Revisiting Disk Winds in Active Galactic Nuclei as an Origin of Cosmic Gamma-ray and Neutrino Backgrounds
Nobuyuki Sakai, Yoshiyuki Inoue, Ellis R. Owen
The origin of the cosmic neutrino background (CNB) and the cosmic gamma-ray background (CGB) remains uncertain. Accretion disk winds driven by active galactic nuclei (AGNs) have be…
GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
Locating the Production Sites of High-Energy Neutrinos in Blazar Jets
Rui Xue, Yoshiyuki Inoue, Ze-Rui Wang +2
The production sites of high-energy neutrinos in blazar jets remain poorly constrained. In this work, we investigate the physical conditions required for efficient neutrino product…
An AGN in the Antennae galaxies ?
Shinya Komugi, Toshiki Saito, Tomonari Michiyama +5
Time variability is a strong probe of energetic phenomena which occur at small spatial scales, like Active Galactic Nuclei (AGN). We use ALMA observations at 100 GHz executed over…
