These clues are guiding observers, theorists, and computational researchers to new and deep insights about compact objects. The goal of this meeting was to bring together theoreticians, modelers, and observers to discuss the computational astrophysics and observational challenges for the next generation of observatories, focusing on the next generation Very Large Array (ngVLA). The NGVLAs capability to process data quickly will change the focus of astronomers research from finding new celestial sources to spending more time studying known objects in greater detail. The ngVLA opens a new window on the Universe through ultra-sensitive imaging of thermal line and continuum emission down to milliarcsecond resolution, while alsodelivering unprecedented broadband continuum imaging and polarimetry of non-thermal emission. The Visitor Center features an award-winning documentary narrated by Jodie Foster, plus exhibits describing radio astronomy and the VLA telescope.
