Asymmetric structure in Sgr A* at 3mm from closure phase measurements with VLBA, GBT and LMT
Christiaan D. Brinkerink, Cornelia Müller, Heino Falcke +19
We present the results of a closure phase analysis of 3 mm very long baseline interferometry (VLBI) measurements performed on Sagittarius A* (Sgr A*). We have analyzed observations…
BlackHoleCam: fundamental physics of the Galactic center
C. Goddi, H. Falcke, M. Kramer +36
Einstein's General Theory of Relativity (GR) successfully describes gravity. The most fundamental predictions of GR are black holes (BHs), but in spite of many convincing BH candid…
Probing spacetime around Sagittarius A* using modeled VLBI closure phases
R. Fraga-Encinas, M. Moscibrodzka, C. Brinkerink +1
The emission region and black hole shadow of Sagittarius A*, the supermassive black hole at the Galactic Center, can be probed with millimeter Very Long Baseline Interferometry. Ou…
