$\mathcal{M}_{g,n}$ a scheme for $n \gg 0$?
Bjorn's comment under JSE's answer addresses the representability question. The absence of automorphisms automatically yields an algebraic space, but the coarse moduli space is known to be a quasi-projective variety, so you get a scheme. |

This is covered in mathoverflow.net/questions/11253/… . See in particular JSE's answer. |

Maryam Mirzakhani's works
In general, if you want to know about a Fields Medalist's (pre-medal) work, the Laudationes is a good place to start, and is available at the IMU website. |

When an elliptic curve is a quotient of $\mathbb{G}_a$?
The exponential function doesn't converge on the whole Lie algebra. Even after restriction, I think surjectivity would require base change to some period ring. |

When an elliptic curve is a quotient of $\mathbb{G}_a$?
There is a $\mathbb{G}_m$-uniformization of $p$-adic analytic elliptic curves with bad reduction. However, the exponential function isn't $p$-adically entire, so lifting to an additive uniformization seems difficult. |

Automorphisms of a quotient variety
For your example, don't you need your automorphism of $\mathbb{A}^n$ to commute with the action of $k^\ast$? |

You should ask Tyler. It would be unfair for me to delete his contribution without his consent. |
