摘要:

自2002年10月发射以来,INTEGRAL卫星凭借其前所未有的成像能力和20 keV以上的源探测位置精度,彻底改变了我们对硬X射线天空的认识。然而,在INTEGRAL巡天中新发现的许多源的性质是未知的。结合使用现有的信息在较长的波长(主要是软X射线和无线电)和光学光谱的假定对应的这些新的硬X射线对象可以精确定位其确切的性质。继续我们的长期计划自2004年以来运行,在这里,我们报告的分类,通过光学光谱学,19个更多的身份不明或研究不足的高能量源检测与IBIS仪器板载INTEGRAL。

英文摘要:

Since its launch on October 2002, the INTEGRAL satellite has revolutionized our knowledge of the hard X-ray sky thanks to its unprecedented imaging capabilities and source detection positional accuracy above 20 keV. Nevertheless, many of the newly-detected sources in the INTEGRAL sky surveys are of unknown nature. The combined use of available information at longer wavelengths (mainly soft X-rays and radio) and of optical spectroscopy on the putative counterparts of these new hard X-ray objects allows pinpointing their exact nature. Continuing our long-standing program running since 2004, here we report the classification, through optical spectroscopy, of 19 more unidentified or poorly studied high-energy sources detected with the IBIS instrument onboard INTEGRAL.
