Estimation of Magnetic Field Strength in the Turbulent Warm Ionized Medium
Qingwen Wu, Jongsoo Kim, Dongsu Ryu +2
We studied Faraday rotation measure (RM) in turbulent media with the rms Mach number of unity, using isothermal, magnetohydrodynamic turbulence simulations. Four cases with differe…
Observational Evidence for Young Radio Galaxies are Triggered by Accretion Disk Instability
Qingwen Wu
The bolometric luminosities and black hole (BH) masses are estimated by various methods for a sample of young radio galaxies with known ages. We find that the ages are positively c…
Accretion/Jet Activity and Narrow [O III] Kinematics in Young Radio Galaxies
Qingwen Wu, Minfeng Gu, Andrew Humphrey
We estimate black hole masses and Eddington ratios for a sample of 81 young radio galaxies (42 CSS +39 GPS). We find that the average black hole (BH) mass of these young radio gala…
The black hole mass, Eddington ratio, and M_bh-σ_[O III] relation in young radio galaxies
Qingwen Wu
The BH masses and the Eddington ratios for a sample of 65 young radio galaxies [27 GPS and 38 CSS sources] are estimated by various methods. We find that the average BH mass of the…
On the BL Lacertae objects/radio quasars and the FRI/II dichotomy
Ya-Di Xu, Xinwu Cao, Qingwen Wu
In the frame of unification schemes for radio-loud active galactic nuclei (AGNs), FR I radio galaxies are believed to be BL Lacertae (BL Lac) objects with the relativistic jet misa…
