Discovery of a Dense Association of Stars in the Vicinity of the Supermassive Black Hole Sgr A*
S. Elaheh Hosseini, Andreas Eckart, Michal Zajaček +3
We focus on a sample of 42 sources in the vicinity of the bow-shock source IRS 1W (N-sources), located at the distance of north-east of the supermassive black hole (SMBH)…
Mid-Infrared studies of dusty sources in the Galactic Center
Harshitha K. Bhat, Nadeen B. Sabha, Michal Zajaček +5
Mid-Infrared (MIR) images of the Galactic center show extended gas and dust features along with bright IRS sources. Some of these dust features are a part of ionized clumpy streame…
Hyper-massive Black Holes have Faint Broad and Narrow Emission Lines
Harshitha K. Bhat, Susmita Chakravorty, Dhrubojyoti Sengupta +6
The EUV provides most of the ionization that creates the high equivalent width (EW) broad and narrow emission lines (BELs, NELs) of quasars. Spectra of Hypermassive Schwarzschild b…
Near- and mid-infrared observations in the inner tenth of a parsec of the Galactic center -- Detection of proper motion of a filament very close to Sgr~A*
Florian Peißker, Andreas Eckart, Nadeen B. Sabha +2
We analyze the gas and dust emission in the immediate vicinity of the supermassive black hole Sgr~A* at the Galactic center (GC) with the ESO VLT (Paranal/Chile) instruments SINFON…
