re: Spiral stellar density waves and the flattening of abundance gradients in the warm gas component of spiral galaxies
Wonderful. Here, I was just thinking about our Sagittarius Dwarf 'elliptical galaxy' and it's relation to our 'barred spiral' Milky Way galaxy (the DEG was born from a a previous MW collision now to be finally devoured by our MWG).
I know, yes, they are very lucky to be working 24-7 (or close to it) in this field. Technically, they have the chance to get to the nitty gritty and gases thereoff. lol
