Stable cuspidal curves and the integral Chow ring of $\overline{\mathscr{M}}_{2,1}$
In this paper we introduce the moduli stack M̃g,n of n-marked stable at most cuspidal curves of genus g and we use it to determine the integral Chow ring of M 2,1. Along the way, we also determine

The Chow rings of the moduli spaces of curves of genus 7, 8, and 9
The rational Chow ring of the moduli space Mg of curves of genus g is known for g ≤ 6. Here, we determine the rational Chow rings of M7,M8, and M9 by showing they are tautological. One key ingredient

In this paper we introduce the stack of polarized twisted conics and we use it to give a new point of view on M2. In particular, we present a new and independent approach to the computation of the
