    Cross-Correlation of Tenerife Data with Galactic Templates-Evidence for Spinning Dust?
    The recent discovery of dust-correlated diffuse microwave emission has prompted two rival explanations: free-free emission and spinning dust grains. We present...

    Dark Energy Survey Deep Field photometric redshift performance and training incompleteness assessment
    Context. The determination of accurate photometric redshifts (photo-zs) in large imaging galaxy surveys is key for cosmological studies. One of the most common...
