Techniques for Compact Source Extraction in CMB Maps
/ Authors
/ Abstract
The detection of compact sources embedded in a background is a verycommon problem in many fields of astronomy. In these lecture notes, wepresent a review of different techniques developed for the detectionand extraction of compact sources, with an especial focus on theirapplication to the field of the cosmic microwave backgroundradiation. In particular, we will consider the detection ofextragalactic point sources and the thermal and kinematicSunyaev–Zeldovich effects from clusters of galaxies.
