An Extremely Top-Heavy IMF in the Galactic Center Stellar Disks (2009)
Bartko, H., Martins, F., Trippe, S., Fritz, T. K., Genzel, R., Ott, T., ...
We present new observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. Our work allows the...
A new type of stellar explosion (2009)
Perets, H. B., Gal-Yam, A., Mazzali, P., Arnett, D., Kagan, D., Filippenko, A. V., ...
The explosive deaths of stars (supernovae; SNe) are generally explained by two physical processes. Young massive stars (more than eight solar masses, M_Sun) undergo gravitational core-collapse and...
Evidence for warped disks of young stars in the galactic center (2009)
Bartko, H., Martins, F., Fritz, T. K., Genzel, R., Levin, Y., Perets, H. B., ...
Evidence for Warped Disks of Young Stars in the Galactic Center (2008)
Bartko, H., Martins, F., Fritz, T. K., Genzel, R., Levin, Y., Perets, H. B., ...
The central parsec around the super-massive black hole in the Galactic Center hosts more than 100 young and massive stars. Outside the central cusp (R~1") the majority of these O and Wolf-Rayet (WR)...
Vidali, G., Pirronello, V., Li, L., Roser, J., Manico, G., Mehl, R., ...
The study of the formation of molecular hydrogen on low temperature surfaces is of interest both because it allows to explore elementary steps in the heterogeneous catalysis of a simple molecule and...
