The Event Horizon Telescope is an international collaboration working to capture the first image of a black hole by creating a virtual Earth-sized telescope. The collaboration was formed to increase the capability of Very Long Baseline Interferometry (VLBI) observations at short wavelengths. The technique of linking radio dishes across the globe to create an Earth-sized interferometer has been used to measure the size of the emission regions of the two supermassive black holes with the largest apparent event horizons: SgrA* at the center of the Milky Way and M87 in the center of the Virgo A galaxy. Doeleman's group at the Center for Astrophysics | Harvard & Smithsonian, and the Harvard University Black Hole Initiative works on simulations and instrumentation for the EHT effort. This research includes the development of simulation software for refining the telescope array and imaging, and for expansion of the event horizon telescope to enhance its overall capabilities. Future work will include development of next generation instrumentation focused on high-bandwidth systems and will shift to the creation of cloud architectures for enhanced data processing.
