## Abstract

Recently, Zagier expressed an interpolated version of the Apéry numbers for $$\zeta(3)$$ in terms of a critical $$L$$-value of a modular form of weight 4. We extend this evaluation in two directions. We first prove that interpolations of Zagier's six sporadic sequences are essentially critical $$L$$-values of modular forms of weight 3. We then establish an infinite family of evaluations between interpolations of leading coefficients of Brown's cellular integrals and critical $$L$$-values of modular forms of odd weight.
