Journal ArticleDOI
Source-intrinsic near-infrared properties of sgr a*: total intensity measurements
Gunther Witzel,Andreas Eckart,Andreas Eckart,M. N. Bremer,Mohammad Zamaninasab,Banafsheh Shahzamanian,Banafsheh Shahzamanian,Monica Valencia-S.,Monica Valencia-S.,Rainer Schödel,Vladimir Karas,Rainer Lenzen,N. Marchili,Nadeen B. Sabha,Macarena Garcia-Marin,R. M. Buchholz,D. Kunneriath,Christian Straubmeier +17 more
TL;DR: In this article, the statistical properties of the variability of Sgr A* in the near-infrared, which is consistent with a single-state process forming a power-law distribution of the flux density, are characterized.
Journal ArticleDOI
Near-infrared proper motions and spectroscopy of infrared excess sources at the Galactic center
Andreas Eckart,Andreas Eckart,Koraljka Mužić,S. Yazici,Nadeen B. Sabha,Nadeen B. Sabha,Banafsheh Shahzamanian,Banafsheh Shahzamanian,Gunther Witzel,Lydia Moser,Macarena Garcia-Marin,Monica Valencia-S.,Monica Valencia-S.,B. Jalali,M. Bremer,Christian Straubmeier,C. Rauch,C. Rauch,R. M. Buchholz,D. Kunneriath,J. Moultaka,J. Moultaka +21 more
TL;DR: In this article, the authors presented a first K s-band identification and proper motions of the IRS13N member s, the high-velocity dusty S-cluster object (DSO), also referred to as G2, and other infrared excess sources in the central field.
Journal ArticleDOI
Near-infrared proper motions and spectroscopy of infrared excess sources at the Galactic Center
Andreas Eckart,Koraljka Muzic,Senol Yazici,Banafsheh Shahzamanian,G. Witzel,N. Sabha,L. Moser,M. Garcia-Marin,M. Valencia-S.,B. Jalali,M. Bremer,Christian Straubmeier,D. Kunneriath,J. Moultaka +13 more
TL;DR: In this paper, a small but dense cluster of co-moving sources (IRS13N) about 3" west of SgrA* just 0.5" north of the bright IRS13E cluster of WR and O-type stars was found.
Journal ArticleDOI
Investigating the Relativistic Motion of the Stars Near the Supermassive Black Hole in the Galactic Center
M. Parsa,M. Parsa,Andreas Eckart,Andreas Eckart,Banafsheh Shahzamanian,Vladimir Karas,Michal Zajaček,Michal Zajaček,J. A. Zensus,Christian Straubmeier +9 more
TL;DR: In this paper, the relativistic parameters of stars in the S-star cluster near Sgr A were derived from the changes in orbital elements derived from elliptical fits to different sections of the orbit.
