Event Horizon Telescope: Taking the First Picture of a Black Hole

Last April, the Event Horizon Telescope–an Earth-size telescope–was pointed towards the black holes at the centers of our Galaxy and M87, with an unprecedented 10 µas resolution. Its audacious goal is to take the first picture of a black hole at mm wavelengths and obtain direct evidence for event horizons–the mysterious frontier from which nothing can escape. In this colloquium, I will describe the EHT, its scientific goals and the grand challenges involved. I will discuss developments in simulating black hole accretion flows and their expected images using high performance computing. The upcoming EHT observations will open new horizons in black hole astrophysics.
