I assume "a few mas" means milli-arc-seconds. Then we see 40 micro-arc-seconds. Normally I would guess "u-v" means ultraviolet, but it seems out of place here.

The buried lede seems to be that the data they got is also consistent with a point source, but the other guys preferred to reconstruct it as a ring.
- belter 5y agou-v means the uv plane. It's a standard concept in VLBI "The Techniques of Radio Interferometry I: Basics" [PDF]: https://www.astron.nl/astrowiki/lib/exe/fetch.php?media=ra_uva:ra_uva_lecture6.pdf https://www.astron.nl/astrowiki/lib/exe/fetch.php?media=ra_u...
