摘要:

在银河系的中心,距离约为8千秒差距,紧凑的人马座A*(SgrA*)可以与一个约4 × 10 ^6太阳质量的超大质量黑洞联系在一起。SgrA* 显示出从无线电到X射线波长域的强烈变化。在这里,我们报告同时近红外/亚毫米/X射线观测从2007年5月,涉及NACO自适应光学(AO)仪器在欧洲南方天文台的甚大望远镜,澳大利亚望远镜紧凑阵列(ATCA),美国毫米阵列CARMA,IRAM 30毫米望远镜,和其他望远镜。我们专注于毫米/亚毫米数据的时间序列CARMA,ATCA,和MAMBO测辐射热计在IRAM 30米望远镜。

英文摘要:

At the center of the Milky Way, with a distance of ~8 kpc, the compact source Sagittarius A* (SgrA*) can be associated with a super massive black hole of ~4x10^6 solar masses. SgrA* shows strong variability from the radio to the X-ray wavelength domains. Here we report on simultaneous NIR/sub-millimeter/X-ray observations from May 2007 that involved the NACO adaptive optics (AO) instrument at the European Southern Observatory's Very Large Telescope, the Australian Telescope Compact Array (ATCA), the US mm-array CARMA, the IRAM 30m mm-telescope, and other telescopes. We concentrate on the time series of mm/sub-mm data from CARMA, ATCA, and the MAMBO bolometer at the IRAM 30m telescope.
