High Frequency Astrometry and Pulsar Studies with the Korean VLBI Network

Maria Rioja will report on the Korean VLBI Network (KVN), the first dedicated mm-VLBI array. The 3 telescopes have an innovative multifrequency receiver that allows for simultaneous observations at 22, 43, 86 &129GHz. With care these can be phase referenced to allow astrometry at these frequencies. I will show our first results of phase referencing at 132GHz and the path to compatible global VLBI.

Richard Dodson will discuss a slightly crazy pulsar project we are undetaking with the Korean and Japanese telescopes (http://arxiv.org/abs/1407.4605). We have method for a coherent, full field of view, blind search for pulsars in the time domain. This is an important step for the SKA facilities. The current target for KVN/KAVA is the search for galactic centre pulsars - which will provide the strong-gravity regime tests of general relativity. I will review what we tried, what we found and what we will try next.
