A remarkable achievement and great recognition for your team - well done!
I had a quick look at the Journal Citation Reports entry for The Astrophysical Journal, and it's a highly cited journal in astrophysics (i.e. many other academics read and cite work published in that journal).
In case others are interested in taking a look, a pre-print is available for free download here:

The published article is behind a paywall, but here's the link if you have institutional/university access:
