Caravan-Submm, Black Hole Imager in the Andes

Figure 8

Imaging simulation for u-v coverage. (a) Model image of edge-on view RIAF accretion disk with 50 μas black hole shadow at the center. Total flux density is 3 Jy. (b) Result from only global longer baselines without phased-ALMA. (c) Result from only global longer baselines with phased-ALMA. (d) Result from combination of global longer baselines plus Caravan-submm array without phased-ALMA. (e) Result from combination of global longer baselines plus Caravan-submm array with phased-ALMA. Here we assumed 1024 MHz recording bandwidth.
