银河系黑洞Swift J1753 .5-0127的喷流淬灭
Disk-Jet quenching of the Galactic Black Hole Swift J1753.5-0127
摘要：
我们报告的无线电和X射线监测观测的六六六雨燕J1753.5-0127采取了超过10年的时间。提供的是15 GHz的AMI-LA和Swift XRT和BAT的X射线数据的每日无线电观测。还介绍了一个深2小时JVLA观测采取了一个不寻常的低光度软状态（与低磁盘温度）。我们表明，虽然源一直保持相对无线电安静相比，XRB具有类似的X射线光度在硬态，幂律关系的尺度为$ζ=0.96\pm0.06$，即稍微接近已被认为是辐射效率低的吸积盘。我们还对XRB软态下的射电喷流猝灭提出了迄今为止最严格的限制，表明了喷流猝灭与X射线幂律分量的联系;发现软态下的射电通量为$<21~μ$ Jy，这是$\gtrsim25$的猝灭因子
英文摘要：
We report on radio and X-ray monitoring observations of the BHC Swift J1753.5-0127 taken over a ~10 year period. Presented are daily radio observations at 15 GHz with the AMI-LA and X-ray data from Swift XRT and BAT. Also presented is a deep 2hr JVLA observation taken in an unusually low-luminosity soft-state (with a low disk temperature). We show that although the source has remained relatively radio-quiet compared to XRBs with a similar X-ray luminosity in the hard-state, the power-law relationship scales as $ζ=0.96\pm0.06$ i.e. slightly closer to what has been considered for radiatively inefficient accretion disks. We also place the most stringent limit to date on the radio-jet quenching in an XRB soft-state, showing the connection of the jet quenching to the X-ray power-law component; the radio flux in the soft-state was found to be $<21~μ$Jy, which is a quenching factor of $\gtrsim25$
