Multiple Testing of Local Maxima
for Detection of Peaks on the (Celestial) Sphere

We present a topological multiple testing scheme for detecting peaks on the sphere under isotropic Gaussian noise. We then discuss how this novel multiple testing method can be exploited for point-source detection in Cosmic Microwave Background radiation (CMB) data.

The talk is based on a joint paper with V. Cammarota, D. Cheng, Y. Fantaye and A. Schwartzman, to appear in Bernoulli (2018+).
