Shoko Koyama

Welcome to Shoko's homepage! 

I am an radio astronomer. I am a researcher at College of Creative Studies, Niigata University, in Japan. 

I am interested in the observational studies related to active galactic nuclei (AGN) jets and black holes by mainly using Very Long Baseline Interferometry (VLBI).

I participate in the Event Horizon Telescope (EHT) Collaboration, which is an international collaboration aiming to directly capture the first image of a black hole by creating a virtual Earth-sized telescope. I participate in a series of the EHT works, proposal writings (blazars), data reduction, imaging, and physical interpretations.
