ALMA Observations of DEM L241/LMC P3 in the Large Magellanic Cloud: Evidence for the Formation of Cool Molecular Jets Driven by a Microquasar
Yasuo Fukui, Bhuvana G. R., Hidetoshi Sano +17
We present ALMA observations of DEML 241/LMC P3, the most luminous -ray binary consisting of a compact object and an O star, in CO emission. We have found an one-sided jet-like…
Molecular and Atomic Gas Associated with the Gamma Ray Supernova Remnant RCW 103
H. Inoue, Y. Asano, R. G. Bhuvana +15
We present a study of the interstellar molecular and atomic gas associated with the gamma-ray supernova remnant (SNR) RCW 103 using the Mopra CO( = 1-0), Atacama Large Mi…
Observations of ionized carbon towards the -ray-bright supernova remnant RX J1713.7-3946
A. R. Thakur, G. P. Rowell, R. Higgins +7
The origin of Galactic Cosmic Rays (CRs), particularly at sub-GeV energies, remains uncertain due to their difficulty in being traced. One possible tracer of low-energy CRs is ioni…
Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission
Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7
We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…
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-wavelength…
Optical observations and atomic environment of supernova remnant G25.1-2.3
Ebru Aktekin, Hicran Bakış, Volkan Bakış +4
The supernova remnant (SNR) G25.1-2.3 was identified in the radio band during the Sino-German 6 cm survey of the Galactic plane. We present a detailed investigation of the optic…
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…
Turbulent Magnetic Fields and Molecular Cloud Interactions in the Supernova Remnant G1.9+0.3
Moeri Tao, Takaaki Tanaka, Hidetoshi Sano +2
We present on results of a spatially resolved spectral analysis of G1.9+0.3, the youngest known supernova remnant in the Galaxy. The X-ray spectra are well described by synchrotron…
Chandra Large Project Observations of the Supernova Remnant N132D: Measuring the Expansion of the Forward Shock
Xi Long, Paul P. Plucinsky, Terrance J. Gaetz +15
We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of t…
