230 GHz VLBI Observations of M87: Event-horizon-scale Structure During an Enhanced Very-high-energy Y-ray State in 2012
- Description:
- We report on 230 GHz (1.3 mm) very long baseline interferometry (VLBI) observations of M87 with the Event Horizon Telescope using antennas on Mauna Kea in Hawaii, Mt. Graham in Arizona, and Cedar Flat in California.
