A. Ballone, M. Schartmann, A. Burkert, S. Gillessen, R. Genzel, T.K. Fritz, F. Eisenhauer, O Pfuhl, T. Ott The origin of the dense gas cloud "G2" discovered in the Galactic Center (Gillessen et al. 2012) is still a debated puzzle. G2 might be a diffuse cloud or the result of an outflow from an invisible star embedded in it. I will present the first attempt of detailed simulations of...

The Sagittarius B2 (SgrB2) molecular cloud is a well-known region of high-mass star formation close to the Galactic Center. Its hot molecular core SgrB2 (M) contains at least 36 HII regions and 12 sub-mm cores. A full line survey of SgrB2 (M) has been obtained using the HIFI spectrometer aboard of the Herschel Observatory as part of the guaranteed-time key-project "Herschel/HIFI Observations...
