dc.description.abstractWe report on a successful, simultaneous observation and modeling of the sub-millimeter to near-infrared flare emission of the Sgr A* counterpart associated with the super-massive black hole at the Galactic center. Our modeling is based on simultaneous observations that have been carried out on 03 June, 2008 using the NACO adaptive optics (AO) instrument at the ESO VLT and the LABOCA bolometer at the APEX telescope. Inspection and modeling of the light curves show that the sub-mm follows the NIR emission with a delay of 1.5+/-0.5 hours. We explain the flare emission delay by an adiabatic expansion of the source components.en_US
dc.description.sponsorshipWe are grateful to all the ESO PARANAL and Sequitor staff, and especially to the members of the NAOS/CONICA, VLTI, and APEX team. The observations were made possible through a special effort by the APEX/ONSALA staff to have the LABOCA bolometer ready for triggering. Leo Meyer is supported by the DAAD exchange program. Macarena García-Marín is supported by the German federal department for education and research (BMBF) under the project numbers: 50OS0502 & 50OS0801. The X-ray work was supported by NASA through Chandra award G05-6093X. M. Zamaninasab, D. Kunneriath, and R.-S.
