There has been quite the uptick recently—is it just Poisson statistics or have there been meaningful instrumental improvements (or more simultaneous up time?) or something?

cplberry.bsky.social•475 days ago

There has been steady progress in the detectors. I think this is mostly Poisson though

saavikford.bsky.social•475 days ago

Yeah. Those of us considering follow up have been getting a real-life reminder of how Poisson works…

Just keep swimming!

I’d really rather eat the fish!!! 😂 Also, time clustered ToOs piss off everyone. Oh well, they’ll hopefully get over it…

I haven't the faintest idea of how to interpret these diagrams, but I do know they represent a stellar phenominon. Stellar Pheomina are awesome, therefore the diagrams are awesome, and you are awesome for making these diagrams available to my eyeballs. Thank you, awesome science person.

If you'd like to interpret: the diagrams show the potential source location. Darker red = higher probability.

The first plot shows the position on the sky. With only 2 detectors, we often get a large band

The second shows the 3D position with the Earth in the middle as the ⊕. The blue plot shows the probability of different distances regardless of direction

I wrote a bit more about the information we release in the LIGO Magazine https://www.ligo.org/magazine/LIGO-magazine-issue15.pdf#page=6

I'm super excited that you think gravitational-wave astronomy might be awesome. Thank you for making my day
