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…
Long Gamma-Ray Bursts and Their Host Galaxies at High Redshift
A. Lapi, N. Kawakatu, Z. Bosnjak +4
Motivated by the recent observational and theoretical evidence that long Gamma-Ray Bursts (GRBs) are likely associated with low metallicity, rapidly rotating massive stars, we exam…
Coevolution of Supermassive Black Holes and Circumnuclear Disks
Nozomu Kawakatu, Keiichi Wada
We propose a new evolutionary model of a supermassive black hole (SMBH) and a circumnuclear disk (CND), taking into account the mass-supply from a host galaxy and the physical stat…
Nuclear/Circumnuclear Starbursts and Active Galactic Nuclei Mass Accretion in Seyfert Galaxies
Yasuyuki Watabe, Nozomu Kawakatu, Masatoshi Imanishi
We investigated the correlation between nuclear/circumnuclear starbursts around the active galactic nuclei (AGNs) and the AGN activities for 43 Seyfert galaxies in the CfA and 12 m…
