Discovery of Molecular and Atomic Gas associated with HESS J1646-458 (Westerlund 1): Spatial TeV Gamma-Ray and Interstellar Proton Correspondence
H. Sano, Y. Fukui, S. Fujimori +21
We report CO and HI studies of molecular and atomic gas toward the TeV gamma-ray source HESS J1646458, widely considered to be associated with the young massive cluster Westerlu…
Sub-kpc scale gas density histograms of the nearby barred spiral galaxy M83: Multi-component molecular gas structure reflecting the galactic environment
Ren Matsusaka, Toshihiro Handa, Fumi Egusa +8
We investigate the sub-kiloparsec (sub-kpc) molecular ISM structure and its relation to the galactic environment and star formation in the barred spiral galaxy M83 (NGC 5236). We e…
Hadronic Scenario for Galactic PeVatron LHAASO J1912+1014u Supported by Fermi-LAT -ray Data and FUGIN CO Data
Tsunefumi Mizuno, Hidetoshi Sano, Takeru Murase +3
LHAASO has reported 43 sub-PeV -ray sources, which are promising candidates for cosmic-ray (CR) accelerators above the PeV energy, commonly called as PeVatrons. Multi-wavelengt…
Gas Kinematics and Cosmic-Ray Acceleration in the Gamma-ray SNRs W41 and G22.7-0.2
Takeru Murase, Hidetoshi Sano, Kohei Matsubara +13
We present a study of the interstellar medium associated with the two middle-aged supernova remnants (SNRs) W41 and G22.7-0.2, both detected in TeV gamma-rays. Using high-angular-r…
KAgoshima Galactic Object survey with Nobeyama 45-metre telescope by Mapping in Ammonia lines (KAGONMA): Discovery of parsec-scale CO depletion in the Canis Major star-forming region
Yushi Hirata, Takeru Murase, Junya Nishi +6
In observational studies of infrared dark clouds, the number of detections of CO freeze-out onto dust grains (CO depletion) at pc-scale is extremely limited, and the conditions for…
