Why is the roof so new?

Not to mention the floor. I'm currently ~2.8kly below Sgr A* and the floor of the galaxy in the core is a carpet of T Tauris. A couple of months ago I was ~2.8kly above and the ceiling is the same.

Does anyone know if these thin layers of new stars sandwiching the core are something we'd expect to see in the real Milky Way and why?

As far as I know star density near the core is too high to be sure about anything using today's resources.

Here's a paper about the distribution of T-Tauri stars: http://articles.adsabs.harvard.edu/pdf/1996ApJ...468..306F

Edit: And a paper about star distribution near the galactic center: https://arxiv.org/ftp/arxiv/papers/1006/1006.0064.pdf

And since the first paper told us that T-Tauri stars form in molecular clouds here's a paper about the distributioon of molecular clouds in the milky way :) https://www2.mpia-hd.mpg.de/~beuther/heyer2015.pdf
