第一类活动星系核的XBS样本:射电响度与物理参数的关系
The XBS sample of type 1 AGNs: Radio loudness vs. physical parameters
摘要:
利用XMM-Newton Bright Survey(XBS)中选取的~190 1型活动星系核,研究了活动星系核射电响度与中心黑洞质量的关系。我们发现,射电噪声活动星系核在高黑洞质量下更常见,与质量在10^7-10^9 Msun之间的活动星系核相比,质量>10^9 Msun的活动星系核的频率要高出10倍。
英文摘要:
We have studied the relationship between the AGN radio-loudness and the mass of the central black-hole by using the ~190 type 1 AGN selected in the XMM-Newton Bright Survey (XBS). We find that radio-loud AGNs are much more frequent at high black-hole masses being a factor ~10 times more common for masses >10^9 Msun when compared to masses between 10^7-10^9 Msun.
