PKS 0743$-$67: An Ultra-luminous Accretion Disk and a High Kinetic Luminosity Jet | | Brian Punsly

3 Oct 2005 | | Subject: | astro-ph | | Abstract: | In this letter, deep radio observations of the quasar PKS 0743$-$67 are presented that reveal a central engine capable of driving jets with enormous kinetic luminosity, $Q>4.1 imes 10^{46}mathrm{ergs/s}$. This result is significant because archival optical spectral data indicates that the accretion disk has a thermal luminosity, $L_{bol}>2 imes 10^{47}mathrm{ergs/s}$. Furthermore, estimates of the central black hole mass from line widths indicate that $L_{bol}/L_{Edd}approx 1$. This suggests that neither a large $L_{bol}$ nor $L_{bol}/L_{Edd}$ suppresses jet power in quasars, despite claims that they do in the recent literature. Earlier studies have found $L_{bol}$ and $Q$ are correlated in blazars. However, by removing the BL-Lacs and leaving only the quasars in the sample, we found that $Q$ is very weakly correlated with $L_{bol}$ in the subsample. | | Source: | arXiv, astro-ph/0510044 | | Services: | Forum | Review | PDF | Favorites | |
