Coordinated mm/sub-mm observations of Sagittarius A* in May 2007
7 pags., 3 figs. -- The Universe under the Microscope – Astrophysics at High Angular Resolution, 21–25 April 2008, Bad Honnef, Germany ; 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 4x 106M⊙. 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. © 2008 IOP Publishing Ltd. ; Part of this work was supported by the German Deutsche Forschungsgemeinschaft, DFG via grant SFB 494.
