X3: a high-mass Young Stellar Object close to the supermassive black hole Sgr~A*
Florian Peißker, Michal Zajacek, Nadeen B. Sabha +10
To date, the proposed observation of Young Stellar Objects (YSOs) in the Galactic center (GC) still raises the question where and how these objects could have formed due to the vio…
Thermal imaging of dust hiding the black hole in the Active Galaxy NGC 1068
Violeta Gamez Rosas, Jacob W. Isbell, Walter Jaffe +49
In the widely accepted 'Unified Model' solution of the classification puzzle of Active Galactic Nuclei, the orientation of a dusty accretion torus around the central black hole dom…
The apparent tail of the Galactic center object G2/DSO
Florian Peißker, Michal Zajacek, Andreas Eckart +6
The observations of the near-infrared excess object G2/DSO induced an increased attention towards the Galactic center and its vicinity. The predicted flaring event in 2014 and the…
First observed interaction of the circumstellar envelope of an S-star with the environment of Sgr A*
Florian Peißker, Basel Ali, Michal Zajaček +7
Several publications highlight the importance of the observations of bow shocks to learn more about the surrounding interstellar medium and radiation field. We revisit the most pro…
Constraining the accretion flow density profile near Sgr A* using the -band emission of the S2 star
S. Elaheh Hosseini, Michal Zajaček, Andreas Eckart +2
The density profile of the ambient medium around a supermassive black hole plays an important role in understanding the inflow-outflow mechanisms in the Galactic Centre. We constra…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
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)…
