Kavli Affiliate: W. L. Kimmy Wu | Summary:Galaxy clusters identified from the Sunyaev Zel’dovich (SZ) effect are a key ingredient in multi-wavelength cluster-based cosmology. We present a comparison between two methods of cluster identification: the standard Matched Filter (MF) method in SZ cluster finding and a method using Convolutional Neural Networks (CNN). We further implement […]
Kavli Affiliate: Nergis Mavalvala | Summary:The motion of a mechanical object — even a human-sized object — should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: the thermal environment masks any quantum signature of the object’s motion. Indeed, the thermal environment also masks effects of proposed […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Bradford Snios, Daniel A. Schwartz, Aneta Siemiginowska, Małgosia Sobolewska, Mark Birkinshaw | Summary: We present Chandra X-ray observations of 14 radio-loud quasars at redshifts $3 < z < 4$, selected from a well-defined sample. All quasars are detected in the 0.5-7.0 keV energy band, and resolved […]
