The first proper motion measurement of the acceleration regions in the large-scale jets of SS 433 powering the W50 nebula
Naomi Tsuji, Yoshiyuki Inoue, Dmitry Khangulyan +10
We report on new Chandra ACIS-I observations of the X-ray knots located in the western and eastern lobes of W50 associated with the parsec-scale jets of the Galactic microquasar SS…
The possibility of multi-TeV secondary gamma rays from GRB221009A
Oleg Kalashev, Felix Aharonian, Warren Essey +2
The brightest gamma ray burst (GRB) ever observed, GRB221009A, produced a surprisingly large flux of gamma rays with multi-TeV energies, which are expected to be absorbed in intera…
X-ray Study on Propagation of Non-thermal Particles in Microquasar SS 433/W 50 Extended Jets
Kazuho Kayama, Takaaki Tanaka, Hiroyuki Uchida +5
SS 433, located at the center of the W 50 radio nebula, is a binary system that ejects jets oriented east-west with precessional motion. X-ray lobes, containing compact "knots" lab…
Neutrinos and gamma rays from beta decays in an active galactic nucleus NGC 1068 jet
Koichiro Yasuda, Nobuyuki Sakai, Yoshiyuki Inoue +1
We show that TeV neutrinos and high-energy gamma rays detected from the nearby active galaxy NGC 1068 can simultaneously be explained in a model based on the beta decays of neutron…
On the possible contributions of two nearby blazars to the NGC 4151 neutrino hotspot
Anastasiia Omeliukh, Samuel Barnier, Yoshiyuki Inoue
The origin of the high-energy astrophysical neutrinos discovered by IceCube remains unclear, with both blazars and Seyfert galaxies emerging as potential sources. Recently, the Ice…
