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 Tate-Shafarevich group and the conjecture of Birch-Swinnerton-Dyer for Abelian schemes over higher dimensional bases over finite fields can be found here:

Thank you very much for this answer! I have edited my original question above: You may assume knowledge of representation theory of finite groups (as in Serre), algebraic groups and étale cohomology. |

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). |
