本文验证射电弱赛弗特1型星系GRS 1734-292与伽马射线源的对应关系,发现其与EGRET探测结果关联合理但Fermi/LAT最新定位不支持,建议开展数十GHz射电观测解决问题。
AI 中文摘要
已有研究提出,射电弱赛弗特星系GRS 1734-292是3EG J1736-2908及邻近Fermi/LAT源的对应体。本文验证该对应关系,考虑到射电弱可能源于相对论性喷流的自由-自由吸收。结果显示,其与EGRET探测结果的关联具有合理性,但最新的Fermi/LAT定位结果不再支持GRS 1734-292,需开展新观测,尤其是数十GHz的射电观测以解决该问题。
英文摘要
It has been proposed that the radio-weak Seyfert galaxy GRS 1734-292 is the counterpart of 3EG J1736-2908 and of the nearby Fermi/LAT source. I examine this identification, considering that the radio weakness could result from free-free absorption of a relativistic jet. An association with the EGRET detections is plausible, whereas the latest Fermi/LAT localization no longer favors GRS 1734-292. New observations, especially at radio frequencies of tens of GHz, would help to settle the issue.
