Probing the nature of the TeV gamma-ray binary HESS J0632+057 by monitoring Be disk variability
Yuki Moritani, Atsuo T. Okazaki, Alex C. Carciofi +9
We report on monitoring observations of the TeV gamma-ray binary HESS J0632+057, which were carried out to constrain the interaction between the Be circumstellar disk and the compa…
Kanata optical and X-ray monitoring of Gamma-ray emitting Narrow-Line Seyfert 1 and Radio galaxies
Kenji Kawaguchi, Yasushi Fukazawa, Yasuyuki Tanaka +6
Broadband spectrum of AGN consists of multiple components such as jet emission and accretion disk emission. Temporal correlation study is useful to understand emission components a…
Study of the X-ray emission mechanism of radio-loud narrow-line Seyfert 1 galaxy
H. Shirakawa, Y. Fukazawa, Y. Tanaka +2
1H0323+342 is one of narrow-line radio-loud Seyfert 1 galaxies (RL-NLS1), which is a new class of gamma-ray emitting AGNs. Narrow-line Seyfert 1 galaxies (NLS1) have a small-mass b…
Suzaku X-Ray Monitoring of Gamma-Ray-Emitting Radio Galaxy, NGC 1275
Ikumi Edahiro, Yasushi Fukazawa, Kenji Kawaguchi +4
NGC 1275 is a gamma-ray-emitting radio galaxy at the center of the Perseus cluster. Its multi-wavelength spectrum is similar to that of blazers, and thus a jet-origin of gamma-ray…
Study for relation between direction of relativistic jet and optical polarization angle with multi-wavelength observation
Ryosuke Itoh, Yasushi FUkazawa, Yasuyuki T. Tanaka +5
Blazars are thought to possess a relativistic jet that is pointing toward the direction of the Earth and the elect of relativistic beaming enhances its apparent brightness. They ra…
