Detection of a drag force in G2's orbit: Measuring the density of the accretion flow onto Sgr A* at 1000 Schwarzschild radii
S. Gillessen, P. M. Plewa, F. Widmann +14
The Galactic Center black hole Sgr A* is the archetypical example of an underfed massive black hole. The extremely low accretion rate can be understood in radiatively inefficient a…
The Galactic Centre source G2 was unlikely born in any of the known massive binaries
Diego Calderón, Jorge Cuadra, Marc Schartmann +4
The source G2 has already completed its pericentre passage around Sgr A*, the super-massive black hole in the centre of our Galaxy. Although it has been monitored for 15 years, its…
Simulating the pericentre passage of the Galactic centre star S2
M. Schartmann, A. Burkert, A. Ballone
The so-called S2 star reached its closest approach to the massive black hole (BH) at around 1500 in May 2018. It has been proposed that the interaction of its stella…
Thick turbulent gas disks with magnetocentrifugal winds in active galactic nuclei - Model infrared emission and optical polarization
B. Vollmer, M. Schartmann, L. Burtscher +4
(Abridged) Infrared high-resolution imaging and interferometry have shown that the dust distribution is frequently elongated along the polar direction of an AGN. To explain these f…
