Nearly Full-sky Low-multipole Cosmic Microwave Background Temperature Anisotropy. II. Angular Power Spectra and Likelihood

The Astrophysical Journal
We present a cosmic microwave background (CMB) temperature power spectrum measurement at large angular scales from WMAP and Planck maps that were cleaned of foregrounds using a template-based approach described in the first paper of this series.

Integrated Galaxy Light from Stacking 105 Random Pointings in the Dark Energy Survey Data

The Astrophysical Journal
We present a new technique for measuring the integrated galaxy light (IGL) with stacked image data from the Dark Energy Survey (DES). We extract 1′ × 1′ cutouts from nearly 100,000 randomly selected positions in the g, r, i, z, and Y bands from the DES ...

Nearly Full-sky Low-multipole Cosmic Microwave Background Temperature Anisotropy. I. Foreground Cleaned Maps

The Astrophysical Journal
Studies of cosmic microwave background (CMB) are often limited by foreground contamination. Foreground cleaning is performed in either harmonic or pixel space after data cuts have excluded sky areas of strong contamination.
