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超过20 keV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。然而,结合使用较长波长(主要是软X射线和无线电)的现有信息和这些新的硬X射线物体的假定对应物的光谱学可以精确定位它们的确切性质。继续我们自2004年以来运行的长期计划(我们确定了100多个INTEGRAL对象),我们在这里报告了通过光谱学对25个未识别的高能量源的分类,这些高能量源主要属于最近出版的第四次IBIS调查。

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. However, 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 (and with which we identified more than 100 INTEGRAL objects) here we report the classification, through optical spectroscopy, of 25 unidentified high-energy sources mostly belonging to the recently published 4th IBIS survey.
