论文摘要
3C 82在2.87的红移时是最遥远的3C(第三剑桥目录)类星体。因此,拥有宇宙中最具发光的无线电裂片是一个有力的候选人。 3C 82属于紧凑型陡峭的频谱无线电源。我们使用单个盘子和干涉无线电观测值,以对这些强大的无线电裂片的等离子体状态进行建模。据估计,用Leptonic等离子体填充这些裂片的长期时间平均喷气功率为$ \叠加{q} \大约2.66 \ pm 1.33 \ pm 1.33 \ times 10^{47} \ rm {ergs/sec/sec/sec/sec/sec} $,是来自Quasar的最大时间平均射流。假设质子裂片不可用,因为它们需要在形成期间被吸收到中央黑洞的两个数量级的质量传输。该对象获得的第一个高信号到噪声光谱观察结果表明,具有动力$ \ sim 10^{45} \ rm {ergs/sec/sec} $和速度$ \ sim 0.01 $ c。我们还从2018年的宽线和三个时期的紫外线连续体中估计,在三十年中,我们还估计了增值流量的光度光度为$ l _ {\ rm {bol}} \ 3.2-5.8 \ 3.2-5.8 \ times 10^{46} {46} \ rm rm rm {ergs/sec/sec/sec/sec/sec/sec/sec} $。 $ \叠加{q}/l _ {\ rm {bol}} \大约6.91 \ pm 3.41 $的比率也许是任何已知的类星体中最大的。强大的喷气机倾向于强烈抑制电离重型物质的强大风。因此,3C 82提供了一个独特的实验室,用于研究类星体流出启动的中心发动机的动态限制。
3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most luminous radio lobes in the Universe. 3C 82 belongs to the class of compact steep spectrum radio sources. We use single dish and interferometric radio observations in order to model the plasma state of these powerful radio lobes. It is estimated that the long-term time-averaged jet power required to fill these lobes with leptonic plasma is $\overline{Q} \approx 2.66 \pm 1.33 \times 10^{47} \rm{ergs/sec}$, among the largest time averaged jet powers from a quasar. Positing protonic lobes is not tenable since they would require two orders of magnitude more mass transport to the lobes than was accreted to the central black hole during their formation. The first high signal to noise optical spectroscopic observation obtained of this object indicates that there is a powerful high ionization broad line wind with a kinetic power $\sim 10^{45} \rm{ergs/sec}$ and a velocity $\sim 0.01$c. We also estimate from the broad lines in 2018 and the UV continuum in three epochs spread out over three decades that the accretion flow bolometric luminosity is $L_{\rm{bol}} \approx 3.2-5.8 \times 10^{46} \rm{ergs/sec}$. The ratio of $\overline{Q}/L_{\rm{bol}}\approx 6.91 \pm 3.41$, is perhaps the largest of any known quasar. Extremely powerful jets tend to strongly suppress powerful winds of ionized baryonic matter. Consequently, 3C 82 provides a unique laboratory for studying the dynamical limits of the central engine of outflow initiation in quasars.
