论文摘要
Pouliasis等人（2022b）探索了恒星的形成率，黑洞积聚率和在3.5上方的红移处的活跃星系的出色质量，从而发现了高恒星质量下的恒星形成速率的升级，他们认为这是AGN反馈的证据。他们的数据表明，当AGN接近恒星形成速率中曲线的变平 - 恒星质量平面时，吸积率开始下降。我们描述了AGN反馈的性质，这些反馈是通过强大的FRII喷气机提高恒星形成速率的性质，但最终也会触发从近迪丁顿速率转变为以占主导地位的增值的转变。这些系统正处于戏剧性过渡的风口浪尖，该系统从强烈的增强到对恒星形成的大量抑制，这种方式与较高的红移无线电AGN相比，在较低的红移和无射流AGN上产生较陡的无线电AGN坡度。因此，我们认为，Pouliasis等人的数据构成了Singh等人（2021）预测的高红移对象，该物体与Comerford等人（2020）中所示的无线电AGN的低红移行为相连。
Pouliasis et al (2022b) explored star formation rates, black hole accretion rates, and stellar mass of active galaxies at redshift above 3.5, uncovering a leveling off of the star formation rate at high stellar mass, which they consider to be evidence of AGN feedback. Their data shows that as AGN approach the flattening of the curve in the star formation rate - stellar mass plane, the accretion rates begin to drop. We describe the nature of the AGN feedback responsible for this in terms of powerful FRII jets enhancing star formation rates but eventually also triggering a shift in accretion from near-Eddington rates to advection dominated. These systems are on the cusp of a dramatic transition where the active galaxy goes from strong enhancement to large suppression of star formation in a way that produces the steeper slope for radio AGN at low redshift compared to radio AGN at higher redshift and to jetless AGN. We argue, therefore, that the data of Pouliasis et al constitute the high redshift objects predicted by Singh et al (2021) that connect to the low redshift behavior of radio AGN shown in Comerford et al (2020).
