Good News! SARA has plenty of credits active on the 20 Meter Dish at Green Bank once again!

Andrew Thornett and me have mapped the Leo Triplet and here is a preliminary look at the results.

I've overlaid a high resolution HI map from a 2022 Survey by Gang Wu et. al. on our intensity mapping.

The reference survey paper can be found here:

The dish is "IDLE" at the moment due to it being busy with Contractor observations, but my contact at Green Bank said it should be available again on Thursday afternoon.

Cheers!

Oops! I just noticed a typo in the scale units! It should be "K" not "V(km/s)"! I'll correct that in the submission to the journal!

Here are overlays from the same paper but with lower resolution mappings from Arecibo.

I think the plots are beautiful. Are you writing the article? Will you coauthor me? If so put me 2nd!

Congrats with a nice work, Jason and Andrew ... 
Jason, thanks for info about the dish ILDE status.
