Effective divisors in ${\bar{\mathcal{M}}}_{g,n}$ from abelian differentials

We compute many new classes of effective divisors in ${\bar{\mathcal{M}}}_{g,n}$ coming from the strata of abelian differentials and efficiently reproduce many known results obtained by alternate methods. Our method utilises maps between moduli spaces and the degeneration of abelian differentials.
