Microquasar jet-cocoon systems as PeVatrons
B. Theodore Zhang, Shigeo S. Kimura, Kohta Murase
The origin of Galactic cosmic rays (CRs), particularly around the knee region (3 PeV), remains a major unsolved question. Recent observations by LHAAASO suggest that the knee…
Electromagnetic signatures from pulsar remnants of binary neutron star mergers: prospects for unique identification using multi-wavelength signatures
Mainak Mukhopadhyay, Shigeo S. Kimura
Binary neutron star (BNS) mergers can result in the formation of long-lived magnetar remnants which can enhance neutrino and electromagnetic (EM) emissions. In this work, we study…
Formation and Early Evolution of Protoplanetary Disks under Nonuniform Cosmic-Ray Ionization
Erika Nishio, Kengo Tomida, Yuki Kudoh +1
Angular momentum transport by magnetic fields is important for formation and evolution of protoplanetary disks. The effects of magnetic fields are suppressed due to non-ideal magne…
Detection Prospects of Electromagnetic Signatures from OGLE-2011-BLG-0462
Shigeo S. Kimura, Lena Murchikova, Kailash C. Sahu
Stellar-mass isolated black holes (IsoBHs) wandering in interstellar medium (ISM) are expected to be abundant in our Galaxy. Recently, an IsoBH, OGLE-2011-BLG-0462, was unambiguous…
Galactic Isolated Stellar-Mass Black Holes with the Magnetospheric Spark Gap as Possible GeV-TeV Gamma-ray Unidentified Sources
Koki Kin, Riku Kuze, Shigeo S. Kimura
Billions of isolated stellar-mass black holes (IBHs) are thought to wander through the interstellar medium (ISM) in the Galaxy, yet only one has been detected. IBHs embedded in ISM…
Multi-messenger Emission by Magnetically Arrested Disks and Relativistic Jets of Black Hole X-ray Binaries
Riku Kuze, Shigeo S. Kimura, Ke Fang
Black hole X-ray binaries (BHXBs) are observed in various wavelengths from radio to GeV gamma-ray. Several BHXBs, including MAXI J1820+070 and Cygnus X-1, are also found to emit ul…
