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 host galaxies of active galactic nuclei with powerful relativistic jets
A. Olguín-Iglesias, J. León-Tavares, J. K. Kotilainen +6
We present deep Near-infrared (NIR) images of a sample of 19 intermediate-redshift () radio-loud active galactic nuclei (AGN) with powerful relativistic jets ($L_{1.4GHz…
Persistent Asymmetric Structure of Sagittarius A* on Event Horizon Scales
Vincent L. Fish, Michael D. Johnson, Sheperd S. Doeleman +69
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on…
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…
