• Moduli space of curves
• Faber's conjecture
• Tautological ring
• Intersection numbers
• Double ramification cycles

We give a new proof of Faber's intersection number conjecture concerning the top intersections in the tautological ring of the moduli space of curves M-g. The proof is based on a very straightforward geometric and combinatorial computation with double ramification cycles.
