You Say You Want Resolution?: VLBI Capabilities, Limitations, and Science Applications

Very long baseline interferometry (VLBI) offers the highest angular resolution possible in modern astronomy. From tracking the expansion of supernovae in other galaxies, to resolving the event horizon of the black hole in the center of the Milky Way, VLBI is a powerful tool for studying some of the most exotic phenomena in the Universe. However, there are some limitations to its use due to both physical and practical constraints. I will present an overview VLBI use cases, discuss the advantages of VLBI imaging, and describe some of the constraints associated with VLBI. I will conclude with exciting results from studying classical novae with VLBI.
