Combining with a very narrow FOV, it created the 40 micro-asec ring structure. The u-v coverage of EHT lack about 40 micro-asec fringe spacings. Also, the rings are very sensitive to the FOV size. The ring-like structures of the EHTC can be created not only from the public data, but also from the simulated data of a point image. Our analysis shows that (a) the structure at 230 GHz is consistent with those of lower frequency VLBI observations, (b) the jet structure is evident at 230 GHz extending from the core to a few mas, though the intensity rapidly decreases along the axis, and (c) the unresolved core is resolved into bright three features presumably showing an initial jet with a wide opening angle of about 70 deg. Our result is different from the image published by the EHTC. We report our independent image reconstruction of the M 87 from the public data of the Event Horizon Telescope Collaborators (EHTC).
It says inside the manuscript (though not in the arXiv entry) that it was accepted for publication in ApJ on 5th May, though it has not yet appeared there. Following on from yesterday’s post here is an arXiv preprint that I’ve only just seen, though it was submitted on Tuesday 10th May, ahead of yesterday’s announcement about Sagittarius A*.
