Micro-arcsecond structure of Sagittarius A* revealed by high-sensitivity 86 GHz VLBI observations
Christiaan D. Brinkerink, Cornelia Müller, Heino D. Falcke +21
The compact radio source Sagittarius~A (Sgr~A)in the Galactic Center is the primary supermassive black hole candidate. General relativistic magnetohydrodynamical (GRMHD) si…
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…
The Intrinsic Shape of Sagittarius A* at 3.5-mm Wavelength
Gisela N. Ortiz-León, Michael D. Johnson, Sheperd S. Doeleman +19
The radio emission from Sgr A is thought to be powered by accretion onto a supermassive black hole of at the Galactic Center. At millimete…
Molecular gas and dust in the highly magnified z = 2.8 galaxy behind the Bullet Cluster
Daniel Johansson, Cathy Horellou, Omar Lopez-Cruz +8
The gravitational magnification provided by massive galaxy clusters makes it possible to probe the physical conditions in distant galaxies that are of lower luminosity than those i…
