The Optical/Near-Infrared Extinction Law In Highly Reddened Regions
M. W. Hosek, J. R. Lu, J. Anderson +6
A precise extinction law is a critical input when interpreting observations of highly reddened sources such as young star clusters and the Galactic Center (GC). We use Hubble Space…
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…
Search for a Variation of the Fine Structure around the Supermassive Black Hole in Our Galactic Center
A. Hees, T. Do, B. M. Roberts +11
Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond General Relativity and the standard model motivated by unificatio…
Ground Layer Adaptive Optics for the W. M. Keck Observatory: Feasibility Study
J. R. Lu, M. Chun, S. M. Ammons +12
Ground-layer adaptive optics (GLAO) systems offer the possibility of improving the "seeing" of large ground-based telescopes and increasing the efficiency and sensitivity of observ…
The Keplerian orbit of G2
L. Meyer, A. M. Ghez, G. Witzel +8
We give an update of the observations and analysis of G2 - the gaseous red emission-line object that is on a very eccentric orbit around the Galaxy's central black hole and predict…
A Search for a Surviving White Dwarf Companion in SN 1006
W. E. Kerzendorf, G. Strampelli, K. J. Shen +5
Multiple channels have been proposed to produce Type Ia supernovae, with many scenarios suggesting that the exploding white dwarf accretes from a binary companion pre-explosion. In…
