my research focuses on studying super massive black holes with sufficient resolution to directly observe the event horizon itself. To do this our group assembles global networks of telescopes that observe at millimeter wavelengths to create an Earth-size virtual telescope using the technique of Very Long Baseline Interferometry (VLBI). We target SgrA*, the 4 million solar mass black hole at the center of the Milky Way, and M87, a giant elliptical galaxy, for this work. Both of these objects present to us the largest apparent event horizons in the Universe, and both can be resolved by (sub)millimeter VLBI arrays.
