Local Helioseismology of Active Regions and Quiet-Sun Granulation :

Local helioseismology is a powerful tool for probing the solar interior. I will present recent local helioseismic measurements of solar active regions and results from supporting modeling efforts. Some of these measurements are apparently inconsistent with predictions obtained from standard models. In addition, I will show local helioseismic measurements of granulation and preliminary modeling work aimed at confronting convection simulations with these measurements.
