A 600 minute near-infrared lightcurve of Sagittarius A*
L. Meyer, T. Do, A. Ghez +5
We present the longest, by a factor of two, near-infrared lightcurve from Sgr A* - the supermassive black hole in the Galactic center. Achieved by combining Keck and VLT data from…
First VLTI infrared spectro-interferometry on GCIRS 7 - Characterizing the prime reference source for Galactic center observations at highest angular resolution
J. -U. Pott, A. Eckart, A. Glindemann +5
Investigating the environment of the massive black hole SgrA* at the center of the Galaxy requires the highest angular resolution available to avoid source confusion and to study t…
Late-time observations of SN2006gy: Still Going Strong
Nathan Smith, Ryan J. Foley, Joshua S. Bloom +9
Owing to its extremely high luminosity and long duration, SN2006gy radiated more energy in visual light than any other known SN. Two hypotheses to explain its high luminosity -- th…
Follow-up observations of binary ultra-cool dwarfs
H. Bouy, E. L. Martin, W. Brandner +12
Astrometric observations of resolved binaries provide estimates of orbital periods and will eventually lead to measurement of dynamical masses. Only a few very low mass star and br…
Dynamical Masses for Pre-Main Sequence Stars: A Preliminary Physical Orbit for V773 Tau A
A. F. Boden, G. Torres, A. I. Sargent +9
We report on interferometric and radial-velocity observations of the double-lined 51-d period binary (A) component of the quadruple pre-main sequence (PMS) system V773 Tau. With th…
A Constant Spectral Index for Sagittarius A* During Infrared/X-ray Intensity Variations
S. D. Hornstein, K. Matthews, A. M. Ghez +5
We report the first time-series of broadband infrared (IR) color measurements of Sgr A*, the variable emission source associated with the supermassive black hole at the Galactic Ce…
