Cool Core Bias in Sunyaev-Zel’dovich Galaxy Cluster Surveys

Posted by Chicago

Kavli Affiliate: Bradford Benson | First 5 Authors: Henry W. Lin, Michael McDonald, Bradford Benson, Eric Miller, | Summary: Sunyaev-Zeldovich (SZ) surveys find massive clusters of galaxies by measuring the inverse Compton scattering of cosmic microwave background off of intra-cluster gas. The cluster selection function from such surveys is expected to be nearly independent of […]

Subwavelength edge detection through trapped resonances in waveguides

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Miguel Molerón, Chiara Daraio, , , | Summary: Lenses that can collect the perfect image of an object must restore propagative and evanescent waves. However, for efficient information transfer, e.g., in compressed sensing, it is often desirable to detect only the fast spatial variations of the wave […]
