The Initial Mass Function of the Massive Star-forming Region NGC 3603 from Near-Infrared Adaptive Optics observations
Y. Harayama, F. Eisenhauer, F. Martins
We study the initial mass function (IMF) of one of the most massive Galactic star-forming regions NGC 3603 to answer a fundamental question in current astrophysics: is the IMF univ…
Evidence for a Long-Standing Top-Heavy IMF in the Central Parsec of the Galaxy
H. Maness, F. Martins, S. Trippe +10
We classify 329 late-type giants within 1 parsec of Sgr A*, using the adaptive optics integral field spectrometer SINFONI on the VLT. These observations represent the deepest spect…
On the sensitivity of HeI singlet lines to the FeIV model atom in O stars
F. Najarro, D. J. Hillier, J. Puls +2
Recent calculations and analyses of O star spectra have revealed discrepancies between theory and observations, and between different theoretical calculations, for the strength of…
Variations in the spectral slope of Sgr A* during a NIR flare
S. Gillessen, F. Eisenhauer, E. Quataert +10
We have observed a bright flare of Sgr A* in the near infrared with the adaptive optics assisted integral field spectrometer SINFON. Within the uncertainties, the observed spectrum…
