The X-ray footprint of the CircumNuclear Disk
Enmanuelle Mossoux, Andreas Eckart
We studied the central regions of the Galactic Centre to determine if the CircumNuclear Disk (CND) acts as an absorber or a barrier for the central X-rays diffuse emission. After r…
High resolution observations of Cen A: Yellow and red supergiants in a region of jet-induced star formation?
K. Markakis, A. Eckart, N. Castro +5
We present the analysis of near infrared (NIR), adaptive optics (AO) Subaru and archived HST imaging data of a region near the northern middle lobe (NML) of the Centaurus A (Cen A)…
Nuclear Activity and the Conditions of Star-formation at the Galactic Center
A. Eckart, M. Valencia-S., B. Shahzamanian +15
The Galactic Center is the closest galactic nucleus that can be studied with unprecedented angular resolution and sensitivity. We summarize recent basic observational results on Sa…
The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution
R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70
To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
Investigating the Relativistic Motion of the Stars Near the Supermassive Black Hole in the Galactic Center
M. Parsa, A. Eckart, B. Shahzamanian +4
The S-star cluster in the Galactic center allows us to study the physics close to a supermassive black hole, including distinctive dynamical tests of general relativity. Our best e…
Molecular gas in the immediate vicinity of Sgr A* seen with ALMA
Lydia Moser, Álvaro Sánchez-Monge, Andreas Eckart +9
We report serendipitous detections of line emission with ALMA in band 3, 6, and 7 in the central parsec of the Galactic center at an up to now highest resolution (<0.7''). Among th…
