On the nature of the fast moving star S2 in the Galactic Center
F. Martins, S. Gillessen, F. Eisenhauer +3
We analyze the properties of the star S2 orbiting the supermassive black hole at the center of the Galaxy. A high quality SINFONI H and K band spectrum obtained from coadding 23.5…
Determining the motion of the solar system relative to the cosmic microwave background using type Ia supernovae
Christopher Gordon, Kate Land, Anze Slosar
We estimate the solar system motion relative to the cosmic microwave background using type Ia supernovae (SNe) measurements. We take into account the correlations in the error bars…
New light on the S235A-B star forming region
M. Felli, F. Massi, A. Navarrini +3
The S235A-B star forming region has been extensively observed in the past from the radio to the near-IR, but what was happening in the immediate surroundings of the water maser, pl…
The new complex gravitational lens system HE 0230-2130
L. Wisotzki, N. Christlieb, M. C. Liu +3
We report the discovery of the new gravitational lens system HE~02302130, a QSO at redshift consisting of at least five distinct components. Three of these are clearly…
Cosmic Rays in the Galactic Center Region
Wolfgang Rhode, Torsten A. Ensslin, Peter L. Biermann
EGRET data on the Gamma ray emission from the inner Galaxy have shown a rather flat spectrum, extending to about 50 GeV. It is usually assumed that these gamma-rays arise from the…
Cosmic Parameter Estimation Combining Sub-Degree CMB Experiments with COBE
J. Richard Bond, Andrew H. Jaffe
We describe the Bayesian-based signal-to-noise eigenmode method for cosmological parameter estimation, show how it can be used to optimally compress large CMB anisotropy data sets…
