Fate of baby radio galaxies: Dead or Alive ?
Nozomu Kawakatu, Hiroshi Nagai, Motoki Kino
In order to reveal the long-term evolution of relativistic jets in active galactic nuclei (AGNs), we examine the dynamical evolution of variously-sized radio galaxies [i.e., compac…
New prediction of extragalactic GeV gamma-ray emission from radio lobes of young AGN jets
M. Kino, H. Ito, N. Kawakatu +1
We present a new prediction of GeV -ray emission from radio lobes of young AGN jets. In the previous work of Kino et al. (2007), MeV -ray bremsstrahlung emission was predicte…
The Fate of Young Radio Galaxies: Decelerations Inside Host Galaxies?
Nozomu Kawakatu, Hiroshi Nagai, Motoki Kino
We examine the evolution of variously-sized radio galaxies [i.e., compact symmetric objects (CSOs), medium-size symmetric objects (MSOs), Fanaroff-Riley type II radio galaxies (FRI…
Multifrequency Polarimetry of the Nrao 140 Jet: Possible Detection of a Helical Magnetic Field and Constraints on its Pitch Angle
Keiichi Asada, Makoto Inoue, Masanori Nakamura +2
We present results from multifrequency polarimetry of NRAO 140 using the Very Long Baseline Array. These observations allow us to reveal the distributions of both the polarization…
Time Variation of Rotation Measure Gradient in 3C 273 Jet
Keiichi Asada, Makoto Inoue, Seiji Kameno +1
The existence of a gradient in the Faraday rotation measure (RM) of the quasar 3C 273 jet is confirmed by follow-up observations. A gradient transverse to the jet axis is seen for…
