Yes, please, physics and astronomy. Maybe the same subdivisions as arXiv?

Promising site!

Thanks - I'd love to add these but I was unsure whether they would be appropriate. Going off of the biology section on arXiv - I think there are better ways to subdivide a field. Are there any improvements/consolidation that would be appropriate for those subdivisions on arXiv for physics and astronomy?

Seconded. I'd like to see if the astro-ph sections get any traction here.
