I am a postdoc of Uwe Jannsen interested in arithmetic geometry, especially Arithmetic of Abelian schemes, their $L$functions and étale cohomology.
My two recent articles on the TateShafarevich group and the conjecture of BirchSwinnertonDyer for Abelian schemes over higher dimensional bases over finite fields can be found here:

Evaluation maps for moduli of stable maps
For properness: If one has maps $f: X \to Y$ and $g: Y \to Z$ with $g \circ f$ proper and $g$ separated, then $f$ is proper. If $g \circ f$ is even projective, then $f$ is projective. (This is Hartshorne's "property $\mathcal{P}$".)

Existence of fine moduli space for curves and elliptic curves
Can you give me a reference for "no automorphisms => representable as an algebraic space"?

$\mathcal{M}_{g,n}$ a scheme for $n \gg 0$?
OK, I see. Thank you!

In this thread, Emerton only addresses this question for elliptic curves, and JSE only the question about automorphism groups (not the representability by a scheme).

Yes, you are right, exactly!
