Can you combine the data over longer periods, so that you can expand the effective size to earth's orbital diameter over the course of 6 months? Just coordinating at the global scale seems like a huge accomplishment, but using orbital travel to expand the scope seems like an obvious step.
Do observatories coordinate over such long periods, or is time at a premium?
Awesome project, thank you for your commentary!
- goodcanadian 5y agoThe effective size comes from interfering signals taken simultaneously at widely separated receivers, so no, you cannot increase effective size in that way. What you gain from increasing exposure time is that you can see fainter objects.
- wumpus 5y agoBlack holes change as their accretion disks rotate. If I recall correctly, that timescale is months for M87* and hours for Sgr A*.
- goodcanadian 5y agoFair enough. I suppose you can't even directly benefit from increased exposure times. However, tracking the dynamics seems valuable (as I assume you are doing).
