Source-intrinsic near-infrared properties of Sgr A*: Total intensity measurements
G. Witzel, A. Eckart, M. Bremer +12
We present a comprehensive data description for Ks-band measurements of Sgr A*. We characterize the statistical properties of the variability of Sgr A* in the near-infrared, which…
Flare emission from Sagittarius A*
A. Eckart, M. Garcia-Marin, S. N. Vogel +18
Based on Bremer et al. (2011) and Eckart et al. (2012) we report on simultaneous observations and modeling of the millimeter, near-infrared, and X-ray flare emission of the source…
Beating the confusion limit: The necessity of high angular resolution for probing the physics of Sagittarius A* and its environment: Opportunities for LINC-NIRVANA (LBT), GRAVITY (VLTI) and and METIS (E-ELT)
A. Eckart, N. Sabha, G. Witzel +16
The super-massive 4 million solar mass black hole (SMBH) SgrA* shows variable emission from the millimeter to the X-ray domain. A detailed analysis of the infrared light curves all…
Near-infrared proper motions and spectroscopy of infrared excess sources at the Galactic Center
A. Eckart, K. Muzic, S. Yazici +11
There are a number of faint compact infrared excess sources in the central stellar cluster of the Milky Way. Their nature and origin is unclear. In addition to several isolated obj…
The S-Star Cluster at the Center of the Milky Way: On the nature of diffuse NIR emission in the inner tenth of a parsec
Nadeen Sabha, Andreas Eckart, David Merritt +9
Sagittarius A*, the super-massive black hole at the center of the Milky Way, is surrounded by a small cluster of high velocity stars, known as the S-stars. We aim to constrain the…
